Ranked #8 in "Best Mattress Topper 2026: What 10cm Really Means": https://www.ranked10.co.uk/home/best-mattress-topper

- Price: £16.99 (checked on Amazon UK on 2026-09-11)
- Amazon rating: 4.5 from 428 ratings

At £16.99 this is the cheapest topper in the ranking and the only one whose own specification table disproves its marketing. The bullets sell a gel-infused memory foam topper with cooling technology; the same page lists Material Type: Microfiber and Fabric Type: Microfiber, and the filling weighs 3.25kg — exactly what the fibre rivals here weigh and nowhere near the 6.91kg and 8.16kg of the genuine foam toppers.

None of that makes it a bad buy. It is the only topper here under £20, it is 10cm deep, 74 per cent of its 428 ratings are five stars, and one buyer measured it: yes, it really is 10cm. Just know that you are buying a synthetic fibre topper and not memory foam, whatever the badge says.

## Questions people ask

**Is it memory foam?**

No. The bullets say gel-infused memory foam, but the specification table lists Material Type and Fabric Type as microfiber, and the weight, 3.25kg, matches the fibre toppers rather than the foam ones.

**How thick is it?**

10cm as listed, and one verified buyer measured it and confirmed the depth.

**Why is it so cheap?**

It is a synthetic fibre topper in a quilted cover, made for value rather than support, and it is also sold for sofa beds and camping.

**Will it fit a deep mattress?**

The listing says the corner pockets suit mattresses from 6 to 22 inches thick.

**Can I wash it?**

Yes, the care instructions call for a synthetic wash at 40 degrees and suggest shaking and airing it regularly.

**How many ratings does it have?**

428 at the time of collection, averaging 4.5 stars, with 74 per cent five-star and 3 per cent one-star.
