Superior Flex Foam Bunk & Trundle Mattress – 15cm Medium-Firm Reflex Foam

Prefer a firmer foam mattress for a bunk or trundle? The Rest Relax Superior Flex Foam Mattress is built from a generous 150mm layer of supportive reflex foam for a firmer, even surface that keeps the spine and neck correctly aligned and distributes weight evenly. At a slim 15cm it's ideal for bunk and trundle beds, and the silent all-foam build won't creak. A breathable, high-quality quilted cover keeps the temperature regulated and zips off for washing, and the build is hypoallergenic and dust-mite resistant. Made in the UK to BS 7177, delivered rolled, with a 5-year guarantee.
