Best Single Mattress 2025: 10 Ranked, and the Coil Counts That Do Not Add Up

This is the cheapest listing in the top three and the only one under £100 that publishes a coil count at all: 300 pocket springs, three layers listed, 20.6kg in weight. For £84.99 with a 4.6 score from 4,662 ratings, it also carries the largest review base of any hybrid here.

The build is standard hybrid: individually pocketed springs, a memory foam comfort layer, a polyester blend cover and a tight top. It arrives compressed and rolled, needs 24 to 72 hours to reach full size, and comes with a 100-night trial and a 10-year warranty, plus CertiPUR-US and OEKO-TEX claims.

The catch is the spec sheet itself. The size row says 3FT Single (90x190x26cm); the dimensions row says 190 x 90 x 25cm; the thickness row says 26cm and the depth row says 25cm. Which means the 25cm in the advert title is not what the size field states. If you want one clean number before ordering, this single mattress will not give you one.

The listing leads with a 7-zone spring system covering head, shoulder, waist, hip, knee, leg and feet. The spec table beneath it reads 'Number of Mattress Coils: 1' and 'Number of Layers: 2'. Both numbers come from the same page, and only one of them can be right.

Meanwhile, what you can verify: 26cm thickness repeated in the title, the size row and the dimensions row; 20.4kg; medium firmness; a box top; memory foam over pocket springs; and 5,252 ratings at 4.6. It is a near-twin of the £84.99 model with a box top and a £20 premium on top.

That said, if you are paying the extra £20 for a 7-zone system, the cheaper Vesgantti publishes 300 coils and this one publishes 1. Anyone who wants a spring count they can sanity-check before paying should look further down this list.

At 28cm and 11 inches, this is the thickest single mattress in the list, and at £158.99 the most expensive. It is a 9-zone pocket spring build with gel memory foam, wave memory foam, a 3D breathable mesh side, an anti-slip base and a breathable knitted cover. The spec table, however, carries no coil count field at all.

As a result, the 9-zone claim is described in words and never quantified. Item weight is 16.5kg. That is lighter per centimetre than the 20.6kg at 25cm further up this list, or the 17kg at 25cm further down. Foam densities vary, so it proves nothing on its own — it is simply the only comparison the listing allows.

Who should not buy it: if 28cm is the reason you are paying, you are paying roughly £74 more than the £84.99 Vesgantti for 3cm and no published spring count. At 4.4 from 2,686 ratings it is also the lowest-scoring mattress in the top four.

4.7 from 407 ratings is the highest score here, and 20kg at 25cm puts this in the same weight band as the 20.6kg Vesgantti and the 20.4kg SEZMOONSI. The layer row reads '8.0', a decimal in a count of layers.

In practice the design is familiar: a 7-zone layout with memory foam over individually wrapped pocket springs, a high-density foam core, reinforced edges, and gel and convoluted foam for airflow. It ships vacuum-packed to fit narrow doorways and staircases, expands over about 48 hours, and carries a 10-year warranty and a 100-night trial with OEKO-TEX and CertiPUR-US claims.

By contrast with the two Vesgantti listings, 407 ratings is a thin sample — a high score from a small base is weaker evidence than 4.6 from 4,662. There is also no coil count, so the spring system cannot be checked at all before you buy.

£69.99 buys 15cm of foam at 9.98kg, with 935 ratings at 4.4. This is the memory foam single mattress in the list and the only one with no spring unit at all: the description breaks the build into 1cm of comfort memory foam, 2cm of gel memory foam and 12cm of base foam. That totals 15cm, which is exactly what the item thickness row states.

In practice, 15cm of foam suits a guest room, a bunk, a child's bed or a floor sleeper better than a nightly adult bed. The cover is grey and designed to resist visible marks, the mattress arrives vacuum-sealed, needs 24 to 72 hours to expand, and carries CertiPUR-US and OEKO-TEX claims. Edge support is claimed even without springs.

Do not buy this if you want the feel of a pocket sprung single mattress, or if you sit near the top of a normal adult weight range — there is 10cm less material here than in the 25cm hybrids. No washable cover is specified either.

420 coils is the highest published spring count in this list, and it belongs to a £109.98, 25cm hybrid with a 4.6 score from 98 ratings. The same spec table also says 'Number of Layers: 10'.

Ten layers inside 25cm averages 2.5cm each before you count the springs, which is worth noting rather than trusting. What is stated plainly: a 7-zone layout, gel-infused memory foam, high-density foam, a breathable bamboo cover, medium firmness, 9.5kg and a 100-night home trial.

However, 9.5kg at 25cm is the lighter end of this group — the Happiland is 6.8kg, while the heavier 25cm builds here are 17kg and 20.4kg. And 98 ratings is the smallest sample in the top six, so a 4.6 is not yet a track record.

The advert claims an enhanced 7-zone independent pocket spring design at 27cm. The coil row reads 21 and the layer row reads 1. Across a 90x190cm surface, 21 coils works out at roughly one spring every 28cm. Item weight is 20.4kg, joint-heaviest in this list.

Crucially, the weight is the part that holds up: 20.4kg for 27cm sits in line with the 20.4kg Vesgantti and the 20kg Uliyati. Medium firmness, memory foam, a polyester cover, a stated 120kg maximum weight capacity and rolled, boxed delivery are all listed. Care is wipe-only.

If the spring count matters, look elsewhere: the advert's own arithmetic does not give seven independent zones across 21 coils. Even so, 152 ratings is a small base for a 4.5 score, and the cover cannot be washed — the care instructions are wipe and rotate.

£64.99 is the lowest price in this list, and 7,069 ratings is the largest review base of any mattress here. This is the cheapest 3ft single mattress in the ranking, and its coil row — 200 — is one of only three counts published across the whole top ten.

The spring type is Bonnell, not pocketed. Linked open coils transfer movement across the mattress rather than absorbing it locally, so this suits a solo sleeper better than a shared bed. At the same time, 20cm and 13kg with memory foam over open coils, a cotton cover and a stated medium firmness is a fair amount of mattress for the money. It is described as UK made and fire retardant, and wants rotating weekly for the first six weeks.

The reasons to pause: 4.0 is the lowest score here, and 13% of its ratings are one star with a further 4% at two — 17% at two stars or below. The dimension rows also disagree: one says 190L x 90W x 20Th, another says 200 x 90 x 20, and the thickness row converts 20cm to 7 inches.

6.8kg at 25cm. The other 25cm hybrids in this list run 9.5kg, 17kg and 20.4kg, so this is the lightest by a wide margin — at the standard single mattress 90x190 footprint. There is no coil count, no layer count and no stated weight capacity in the spec table.

In theory the design matches the price: seven individually pocketed spring zones, memory foam, 3D breathable mesh, a Euro top, CertiPUR-US and OEKO-TEX claims, and a 72-hour expansion window after unboxing. In practice, none of the internals are quantified, so 25cm is the only structural number you get for £85.49.

The catch is the review base: 46 ratings, the smallest here, with 8% at three stars and none at one or two. If you want evidence before spending £85.49, this listing has not accumulated it yet.
