Collection: Performance Sleep Systems

A good mattress comes down to a few things that actually matter: consistent support, genuine pressure relief, and materials that hold up over years of use, not just months. It's easy to get distracted by marketing claims when comparing memory foam mattresses online, so we've kept things simple. Every True Rest mattress is built the same way, tested to the same standards, and backed by the same certifications, whichever size you choose.

What Makes a True Rest Mattress Different

Every mattress in our range uses the same three-layer memory foam system: a supportive base layer, a pressure-relieving memory foam layer, and a breathable comfort layer on top. It's a simple structure, built with foam chosen for how it performs over time, not just how it feels in a showroom. Read more about the full Sleep System.

Finding Your Size

Single, Double, or King, the mattress underneath doesn't change. Only the dimensions do. That means you can choose based on your room and your bed frame, not on which size happens to have the better mattress inside. See our full Size Guide.

Built and Certified in the UK

Every True Rest mattress is manufactured in the UK and independently tested to BS 7177 fire safety standards, using CertiPUR™ certified foam. It's also fully recyclable once the cover is removed, so it won't end up sitting in landfill when it's finally time to replace it.
