The best pool pads, compared.
Top pick: TIHOOK felt pad 400 x 400 cm – Agreed 400 x 400 cm, 4.6 kg, and a cutting claim, at about £21.19. Two shared ratings, and waterproof plus permeable in the same bullets. Best value: YISIZES PE cloth 274 x 274 cm – About £9.99, an agreed 274 cm square, and 4.5 from 29 ratings. The shared texts call it a thin sheet. Updated October 2026.
A pool pad is the sheet under an above-ground pool, frame pool, paddling pool, or inflatable hot tub. On amazon.co.uk the same goods appear as a ground cloth, a ground sheet, a liner pad, or a hot tub mat. It does not level a slope, carry the water, or make decking safe for a filled spa. Several pages disagree about size, and UK reviews that mention thickness mostly call the mat thin. Some high star scores sit on one to six ratings. Some review texts are copied across two sizes, so they are not two tests. Those texts are shared with the 335 cm listing and call it a thin sheet. The [pool pad buying guide](/hub/pool-care/pool-pad/sub/pool-pad-buying-guide) is the fit method. A fish-pond liner is not a pool pad. A trade felt roll is a different product, and a stated 300 g/m² on a folded disc does not make that disc a trade liner roll.

Personal buying guide
Question 1 of 2
What footprint did you measure?
The TIHOOK 1728 is a dark green felt square listed at 4 m by 4 m, £21.19, and 4.6 kg, the heaviest weight in this set. It says you can cut it, and it names grass and concrete. It also says the felt is waterproof and that water passes through, which are different claims. The star line is 5.0 from 2 ratings. Those two UK texts are copied onto the 370 cm TIHOOK listing, and one of them is written like a description of a 400 cm mat. Grams per square metre are not stated. The weight is the clearest difference from the PE sheets, not the star score.
Pros
Cons
Best for: You want a cuttable 4 m felt square and you can accept two shared reviews.
Less suitable: You need a stated gsm or reviews that are clearly about this ASIN only.
Specifications
Common questions
Can you cut the 4 m TIHOOK pad?
Yes. The bullet says you can trim it for round, oval, rectangular, square, or irregular pools.
Does it claim grass and concrete?
Yes. The protection bullet names soft grass and hard concrete, and sharp stones. It also claims both waterproofing and water passing through.
How solid is the 5.0 score?
It is 5.0 from 2 ratings. The two UK texts also appear on the 370 cm TIHOOK listing. One reads like a product description. Lucas says it fits and does not shift.
TIHOOK 1730 is a black felt round listed at 370 cm, £37.79, and 2.32 kg. The bullets say you can cut it, and they name grass, concrete, stones, and roots. They also claim both a waterproof surface and water passing through. Grams per square metre are not stated. The star line is 5.0 from 2 ratings, and both UK texts are the texts from the 400 cm square, including a description of a 400 x 400 cm mat. At this price you are paying more than for the heavier 4 m square, without a review that names 370 cm. Check the diameter on arrival.
Pros
Cons
Best for: You measured a round footprint near 370 cm and you will confirm the diameter yourself.
Less suitable: You are using the 5.0 score as proof this size was reviewed.
Specifications
Common questions
Is this the same pad as the 4 m TIHOOK square?
No. This model is 1730, listed at 370 cm round, 2.32 kg, and £37.79. The square is model 1728, 400 cm, 4.6 kg, and £21.19. The two UK review texts are the same on both listings.
Will it protect against roots?
The bullet says it shields a liner from sharp stones, roots, and debris on grass or concrete. That is a seller claim. The UK texts do not describe a root test, and they describe 400 cm.
Can you cut a round 370 cm pad?
The bullet says yes, including for round pools it lists as 8 to 12 ft, and for other shapes.
The Issimober cloth is the lowest price in this set at £6.99, with PE stated, a title size of 200 x 300 cm, and a weight of 540 g. Assembly is listed as not required. The amazon.co.uk star line is 5.0 from 1 rating, and the listing has no review text, so that score does not describe thickness or fit. Grams per square metre and a cutting claim are not stated. You are looking at a small rectangular sheet, and you still have to measure it against the pool.
Pros
Cons
Best for: You measured a footprint inside 200 x 300 cm and you want the cheapest PE sheet in this set.
Less suitable: You need UK review comments on thickness, or a cover for a pool larger than 200 x 300 cm.
Specifications
Common questions
How big is the Issimober cloth?
The title says 200 x 300 cm. The listing has no separate dimensions line and no grams per square metre.
Does it need assembly?
The listing says assembly is not required. It is a foldable PE sheet for inflatable, frame, above-ground, and paddling pools, and for hot tubs.
What do buyers say?
The star line is 5.0 from 1 rating. The listing contains no review text, so praise and complaints are not stated.
Bettsolt's cloth is a 274 cm PE square at £10.99 and 650 g, so it is lighter than the 274 cm YISIZES listing at a slightly higher price. The size is consistent between the size line and the bullet. The star line is 4.8 from 6 ratings. The two UK texts are short and positive, including one use on paving to cover bumps, and neither describes thickness. A 274 cm square does not cover a 305 cm, 10 ft pool. There is no cutting claim and no gsm. It is a small blue sheet with a clean size line and very little review detail.
Pros
Cons
Best for: You want a 274 cm PE square and you are content with two short positive UK reviews.
Less suitable: You need a larger cover or reviews that discuss stones and thickness.
Specifications
Common questions
What size is the Bettsolt cloth?
The size line and the bullet both say 274 x 274 cm, about 8.99 ft. The dimensions line only repeats 2.74 m as a length.
What did the UK reviews say?
Two UK reviews are on the listing. One says as described, with no complaints. One used it on paving slabs to cover bumps and called it perfect. No criticism is written.
Is 4.8 from six ratings a thickness test?
No. The listing does not state grams per square metre or thickness. Six ratings are the star line, and only two review texts are present.
The 274 cm YISIZES cloth is £9.99 and 1.01 kg, with PE in the bullets and Plastic on the material line. The bullet limits it to a diameter below 244 cm, so it is a small square, not a 10 ft cover. The star line is 4.5 from 29 ratings, but the eight UK texts are the same as on the 335 cm ASIN, including the complaint that the pictures show a padded mat and the goods are a thin sheet. Do not read 4.5 as a thickness result. Assembly is listed as required, without saying what you assemble.
Pros
Cons
Best for: Your pool or tub footprint is under 244 cm and you want a cheap PE square.
Less suitable: You want independent reviews of this size, or a cover for an 8 ft-plus pool.
Specifications
Common questions
Will 274 cm cover a 10 ft pool?
A 10 ft pool is about 305 cm across, which is larger than 274 cm. The bullet says diameter below 244 cm, about 8 ft. Measure your pool.
Is it a thick mat?
The highlight says thick. The UK review texts, which are the same eight texts as on the 335 cm YISIZES listing, call it a single-thickness sheet and say it has no padding.
Why is assembly required?
The listing says assembly is required. It does not say what is assembled. The bullets describe unfolding a cloth.
This is the larger YISIZES square, £9.99 and 1.55 kg, titled 335 cm and bulleted at 336 cm. It is ranked 1 in Pool Ground Cloth on the listing, with 4.5 from 29 ratings. The highlight says pools below 11 ft and the bullet says diameter below 300 cm, so the fit line is not one number. UK reviews that discuss the material call it a plain groundsheet, not a thick mat. Those texts are copied on the 274 cm ASIN, so they are not eight fresh reviews of this size alone. It is a cheap PE cover near 3.3 m, not a cushion.
Pros
Cons
Best for: You want a PE square around 3.3 m and you do not expect foam-like padding.
Less suitable: You believed the pictures showed a thick mat, or your pool is over 300 cm.
Specifications
Common questions
Is 335 cm enough for an 11 ft pool?
The highlight says below 11 ft. The bullet says diameter below 300 cm, which is under 10 ft. An 11 ft pool is about 335 cm, so the pool would meet the edge of a 335 cm sheet. Measure.
Did UK buyers find it thick?
Two of the eight UK reviews say it is a single thin sheet, not the padded mat in the pictures, and that it gives no real padding. Other reviews say it did the job under a pool or protected grass.
Are these reviews only about this size?
The same eight UK texts and the same 4.5 from 29 ratings appear on the 274 cm YISIZES listing, which uses the same model number FXDB-888.
This YumSur listing is £33.09, model 300DD33, and it is one of only two pads here that state 300 g/m². The bullets say a 3.3 m round felt you can cut, with moisture passing through, and no bleach. The product dimensions line says 10 x 10 x 10 cm, which cannot be the cover if the bullet is right. The star line is 4.4 from 9 ratings, and the two UK texts are the same texts as on the 4 m model, so they do not prove this size on its own. One of those texts wanted more thickness. Colour and country of origin are not stated.
Pros
Cons
Best for: You want a stated 300 g/m² and a bullet size of 3.3 m, and you will check the parcel.
Less suitable: You need reviews written about 3.3 m, or a colour stated on the listing.
Specifications
Common questions
What does 300 g/m² mean here?
The bullet states 300 g/m² felt. The listing does not state thickness in millimetres. A trade 300 g/m² liner roll is a different product.
Which size do you plan for?
The bullets say 3.3 m for pools within 3.3 m. The product dimensions line says 10 x 10 x 10 cm and 2.59 kg. Treat 10 cm as a catalogue clash, not as the cover, and still check the parcel.
Are the UK reviews about 3.3 m?
The two UK texts are the same as on the 4 m YumSur listing. One describes cushioning under a hot tub. One says the felt was not as thick as expected. A German review on the listing mentions 400 cm and is not a UK rating.
The 4 m YumSur, model 300DD4, is £33.99 with 300 g/m² felt in the bullets and 3.84 kg on the dimensions line. That line also says 10 x 10 x 10 cm, which conflicts with a 4 m cover and should be checked on delivery. It says you can trim it for pools within 4 m, and that you must not bleach it. The 4.4 from 9 ratings matches the 3.3 m listing, and so do the two UK texts: patio cushioning with no curling, and felt thinner than expected. Colour is not stated. It is the larger of the two stated 300 g/m² discs, not a separate body of reviews.
Pros
Cons
Best for: Your pool or tub is within 4 m and you want the larger stated 300 g/m² disc.
Less suitable: You need a millimetre thickness or reviews that are not shared with the other size.
Specifications
Common questions
How is this different from the 3.3 m YumSur?
The bullets say 4 m and the weight line says 3.84 kg, against 3.3 m and 2.59 kg on the other YumSur listing. Both state 300 g/m², both show 4.4 from 9 ratings, and both carry the same two UK review texts.
Can you trim it?
The bullet says yes, for a circular, oval, or irregular pool within 4 m.
Did UK buyers find the 300 g/m² thick?
One UK review liked the cushion under a hot tub on a patio. The other said the felt was not as thick as expected but still a protective layer. Thickness in millimetres is not stated.
KEAGAN YXYCD001 is listed at £37.99 as an 18 ft, 550 cm round black felt pad you can cut, with assembly not required. The weight line is 500 g, which is lighter than every PE sheet in this set, and the dimensions line is a 5.5 m cube rather than a round sheet. The bullets claim waterproof felt that also absorbs water. Among 89 ratings at 3.6, the reviews that are clearly about a mat call it thin felt and say stones still come through. One buyer binned it because of the smell. Other reviews talk about a pool you assemble. Do not treat 18 ft and 500 g as a settled specification.
Pros
Cons
Best for: You only consider it after you have checked the delivered weight and diameter against the title.
Less suitable: You want a heavy pad, a stated gsm, or reviews that all describe the same object.
Specifications
Common questions
Can 500 g be an 18 ft pad?
The title says 18 ft and 550 cm round. The weight line says 500 g. The dimensions line says 5.5 m by 5.5 m by 5.5 m. The listing does not reconcile those figures.
What do UK reviews say about thickness?
Several say it is thin felt, like weed block, and that stones can still be felt. One used it under a 10 ft pool on paving and said it was not very thick but did the job. One said it stank and was binned.
Are all 89 reviews about the mat?
No. Some UK texts describe assembling a pool, chlorine tablets, and a ladder. Those may belong to another product on a shared review line. The star line is still 3.6 from 89.
This YISIZES cloth is £8.99 in PE, and the listing does not agree with itself. The title and the 3.4 m by 2.4 m dimensions describe a rectangle, while the bullet describes a 336 cm square for pools under 300 cm. UK reviews at 3.6 from 28 ratings split between people who used it under a pool or spa and people who found it thin, torn, slippery, or shrunk in the sun. One buyer still added EVA foam. Grams per square metre are not stated. Buy the rectangle only if 2.4 m by 3.4 m is the size you measured, and treat the square bullet as a conflict.
Pros
Cons
Best for: You need a rectangle near 2.4 m by 3.4 m and you accept a thin PE sheet.
Less suitable: You need a confirmed square, a stated gsm, or padding you can feel over stones.
Specifications
Common questions
Which size is this YISIZES cloth?
The title and the dimensions line say 3.4 m by 2.4 m. The size line says 340 x 240 cm. The bullet says 336 cm by 336 cm. Those figures are not the same shape.
Do UK reviews call it thick?
Several UK reviews call it thinner than expected. One still uses EVA foam as well. Others say it protected a paddling pool or a 1.8 m spa. One review says it ripped and was slippery, and one says it shrank in the sun.
Can you cut it?
The listing does not say it can be cut. It does say it folds, and the care line says to avoid sharp objects.
This YumSur pad is £22.99 in black felt, model FUGZYB, weight 1.29 kg. The bullets describe a 3.05 m round pad you can cut, and say moisture passes through. The size line and the dimensions line say 15 cm, so you cannot treat either figure as settled. Grams per square metre are not stated, unlike the £33 YumSur pair. Four UK reviews sit under a 3.5 from 18 ratings: short approval, a felty circle, a thin pad that rolls up, and one outright rejection for hot tubs and pools. The installation line says Floating, as printed on the listing. Buy it only if you can return it when the measured size is not 3.05 m.
Pros
Cons
Best for: You can check the delivered size against 3.05 m and you want a cheaper felt than the 300 g/m² pair.
Less suitable: You need a stated gsm or a listing whose size lines agree.
Specifications
Common questions
Is this a 10 ft pad or a 15 cm pad?
The title and bullets say 3.05 m, or 10 ft. The size line says 15 cm round and the dimensions line says 15 x 15 cm. The listing does not explain the clash.
Is 300 g/m² stated?
No. Unlike the other two YumSur listings in this set, this listing does not state 300 g/m².
What do the UK reviews say?
Four UK texts: one is positive and short, one calls it a circular piece of felty fabric, one says it is thin and rolls up, and one says the itchy material is not meant for a hot tub or pool.
Eleven amazon.co.uk listings were scored on 19 October 2026 from the prices, star lines, and UK review notes on those pages. There was no laboratory thickness test. A size, a grams-per-square-metre line, and a cutting claim are what the listing states. A star rating is not a thickness measurement. The four weights below sum to 100. The highest score is the top pick. Best value is the lowest price that still states one agreed cover size in centimetres, one material, and at least 20 amazon.co.uk ratings, without a line that changes the shape. That rule can pick a sheet that is not the top pick. A 5.0 from 1 rating is not the top pick, and £6.99 with no review text is not the best value.
Amazon evidence
35%Stars contribute, then a volume band for how many ratings sit behind them. Copied UK texts are a deduction, and a larger deduction when those texts describe the other size. Reviews that describe a pool you assemble, rather than the mat, are also a deduction. A 5.0 from one rating is not a thickness result.
Listing fit
35%Points for one material word, a cover size that agrees in shape and in centimetres, grams per square metre when stated, a cutting claim, and a stated weight of at least 4 kg when the size lines agree. Points come off when the same bullets claim a waterproof surface and water passing through, or when the weight line is 500 g against an 18 ft title.
Review outcome
15%No review text scores low. A repeated thin, tear, slip, or shrink theme is recorded as that theme, not as padding. Shared texts are not counted as two tests. Fewer than 10 ratings cap the review points. Stones, smell, and thin felt stay in the note.
Value
15%Price counts after the size fits. An agreed 274 cm square at £9.99 with at least 20 ratings scores highest on this weight, even though the shared texts call it a thin sheet. The £6.99 sheet with no review text does not. A shape conflict, a 10 cm cube line, or 500 g against an 18 ft title scores lower.
A pool pad in this comparison is the sheet under the liner, not a filter, a heater, or a repair patch. On these eleven amazon.co.uk listings the shelf runs from about £6.99 to about £37.99. Start with the footprint in centimetres, then the material, then whether the title, the bullet, and the dimensions line name the same object. A star average is not a thickness measurement.
A pool pad is the sheet under an above-ground pool, a frame pool, a paddling pool, or an inflatable hot tub. On amazon.co.uk the same goods are listed as a ground cloth, a ground sheet, a liner pad, or a hot tub mat. Polyethylene sheets in this set cost about £6.99 to £10.99. Felt discs cost about £21.19 to £37.99. Foam tiles, including Lay-Z-Spa's own protector, are not in this set. A fish-pond liner is not a pool pad.
A 10 ft pool is about 305 cm. A 274 cm square does not cover it. Bestway sells a 16 ft cloth for 15 ft pools. Measure in centimetres, and include frame feet if they must sit on the sheet.
Several listings disagree with themselves: 336 cm square against a 2.4 m by 3.4 m title, 15 cm against 3.05 m, and 10 cm against 4 m. Show both numbers. Do not pick the one that fits the pool you hoped for.
UK reviews that mention thickness mostly call the mat thin. A 5.0 from one rating has no review text. A 4.8 from six ratings is two short texts. Shared texts on two sizes are one set of comments, not two tests. The pad does not level a slope or stop legs sinking into soft ground.
The cover has to be larger than the thing sitting on it. A round pool fits on a square sheet only when the side is at least the diameter. A 10 ft pool is about 305 cm, so the 274 cm squares in this set, Bettsolt and the smaller YISIZES, do not cover it. The YISIZES 274 cm bullet also caps the diameter below 244 cm. The 335 cm YISIZES title is close to 11 ft, while its bullet says diameter below 300 cm, so an 11 ft pool would meet the edge of a 335 cm sheet.
Polyethylene is the waterproof barrier. Bestway calls it the economical layer, especially on concrete. In this set those sheets are Issimober, Bettsolt, and YISIZES, from £6.99 to £10.99. None of them states grams per square metre. Felt is sold as a cushion. TIHOOK, YumSur, and KEAGAN run from £21.19 to £37.99, and millimetres are not stated. Only the two dearer YumSur listings state 300 g/m².
Three typical situations, each with a recommendation from this comparison.
You need a sheet bigger than the pool, including frame feet if they sit on the cloth. A 10 ft pool is about 305 cm, so a 274 cm square does not cover it. The TIHOOK felt square lists 400 x 400 cm and 4.6 kg, with a cutting claim. It is the top pick in this set. The two ratings are shared with the 370 cm listing, and the bullets claim both waterproof and water passing through.
A felt disc is not Lay-Z-Spa's foam protector, and a pad does not reduce the filled weight. The FAQ gives 669 kg for a filled Miami AirJet before users. If the deck is unchecked, call a professional before you buy felt. If you still want a stated 300 g/m² and a 4 m bullet, the YumSur disc at about £33.99 is the larger of that pair. The dimensions line says 10 cm, so check the parcel.
Your footprint is under 244 cm and you want polyethylene, not felt. The YISIZES square at about £9.99 states 274 x 274 cm in the title and the bullet, with 4.5 from 29 ratings. Those texts are shared with the 335 cm listing and call it a thin sheet. It is the best value under that rule. The £6.99 Issimober sheet has one rating and no review text, so it is not the value pick.
The top pick in this set is the TIHOOK felt square at about £21.19. The size lines agree at 400 x 400 cm, the weight is 4.6 kg, and cutting is claimed. It is 5.0 from 2 ratings, those texts are shared with the 370 cm listing, and the bullets claim both waterproof and water passing through. The best value is the YISIZES PE square at about £9.99, 274 x 274 cm, with 4.5 from 29 ratings. The material line also says Plastic, and the UK texts are the same as on the 335 cm listing and call it a thin sheet. A 5.0 from 1 rating is not the top pick, and £6.99 with no review text is not the best value. None of these scores is a lab test or a claim that any pad is the thickest on sale.
TIHOOK felt pad 400 x 400 cm
Agreed 400 x 400 cm, 4.6 kg, and a cutting claim, at about £21.19. Two shared ratings, and waterproof plus permeable in the same bullets.
YISIZES PE cloth 274 x 274 cm
About £9.99, an agreed 274 cm square, and 4.5 from 29 ratings. The shared texts call it a thin sheet.
