Silentnight Bamboo Memory Foam Mattress Topper reviewed

The Silentnight Bamboo Memory Foam Mattress Topper is a 5cm memory foam layer in a bamboo-blend cover, part of Silentnight’s Naturals collection and sold on Tesco Marketplace in single, double and king. It is the topper on tesco.com we would pick for pressure relief.

How it is made

According to the Tesco listing, the topper pairs a 5cm layer of what Silentnight calls high-grade memory foam with a quilted cover made from a bamboo blend, plus an anti-slip base and easy-fit straps. The cover is machine washable, and Silentnight gives a 2-year guarantee. Silentnight credits the bamboo cover with wicking moisture and regulating temperature, which is the maker’s claim rather than something the listing measures.

Sizes and Tesco prices

The seller is eBedding LTD, with free delivery and free 30-day returns through Tesco Marketplace, and prices were checked on 11 October 2026. There is no small double or super king of this model on tesco.com.

Memory foam or fibre?

Memory foam softens under body heat and weight and spreads the load at the shoulders and hips, which is why side sleepers on a hard mattress feel the difference first. This topper reaches the 5cm depth that the National Bed Federation’s Bed Advice UK treats as the starting point for a noticeable change, and the same guide notes that a soft topper can add cushioning and pressure relief. The trade-off is warmth and a slower, hugging feel when you turn over. Fibre toppers such as the Silentnight Anti-Allergy Ultimate 1000 sleep cooler and cost less, but compress where you put the most weight.

Feel and who it suits

We rate it medium soft, 4 out of 10. It suits side sleepers and lighter back sleepers on a firm or slightly tired mattress. Stomach sleepers, who need their hips held level, may sink too far into the foam. Like any topper, it cannot fix a mattress that has sagged into dips, because the foam will follow them.
