Rank #5 in Best Single Mattress 2025: 10 Ranked, and the Coil Counts That Do Not Add Up
Uliyati Gel Memory Foam Single Mattress, 15cm, Grey
Price and rating as shown on Amazon when we collected them. Both change.
The Uliyati single is a 15cm gel memory foam mattress at £69.99, sitting at number five in this guide. Its listing is the one that survives the check the rest of the guide is built around: the three layers it names are 1cm of comfort memory foam, 2cm of gel memory foam and 12cm of supportive base foam, and 1 + 2 + 12 comes to 15cm — the same 15cm the title, the Item Thickness field and the Item Depth field all state. The same fiche also gives 'Number of Layers: 3', so the layer count and the layer breakdown agree with each other and with the thickness.
There is no coil count to sanity-check here, because there are no springs to count: the construction type is memory foam, listed as medium and finished with a smooth top. It weighs 9.98 kg, and because it is 15cm rather than the 25cm of the hybrids the guide weighs against each other, that number is not a like-for-like comparison with them. The 935 ratings carry a breakdown that only displays 100 of them — 75 five-star, 12 four-star, 5 three-star, 2 two-star and 6 one-star. Everything on this page is taken from the Amazon listing, not from any testing we have carried out.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Great appearance. Comfortable to lie down. Memory foam is great with just enough firmness. Inflated within hours.Really easy to move. Fit well to bed.Really low noise if you change position.”
“But it!! I have sciatica, fibromyalgia and knee problems and I'm definitely not a petite lady but I find this so comfortable compared to any other matters I've tried. We brought this as we needed a cheap mattress fory daughter's new bed after moving house and I didn't expect much considering the price.... But! This mattress is fantastic! My daughter sleeps soundly all night, it's more medium firm but she sleeps so much better on this than her old one and I think it will last her years so no need to replace with something more expensive like I was expecting. Honestly worth every penny and more in my opinion! I'm about to buy another one for me and her dad because I think it's great!”

Questions people ask
How thick is the Uliyati single mattress?
The listing gives 15cm in the title and repeats it under Item Thickness, Item Depth and Item Dimensions, which read 190 x 90 x 15cm.
Do the three layers add up to that thickness?
Yes. The bullet lists 1cm comfort memory foam, 2cm gel memory foam and 12cm supportive base foam, and 1 + 2 + 12 is 15cm — the same figure as the stated thickness.
How many coils does it have?
None. The Uliyati is a memory foam mattress rather than a pocket spring one, so there is no coil count on this listing to check.
How long before it can be slept on?
The listing says it reaches 90% of its size a few hours after unpacking and asks for 24-72 hours for it to fully expand.
Is it firm or soft?
The listing describes the Uliyati as Medium.
What is the cover made of?
Polyester, in grey, described as breathable, skin-friendly and dirt-resistant.
