Somnus Memory Foam Mattress

The Somnus is a spring-free mattress built entirely from foam, a pressure-relieving memory foam comfort layer sitting on top of a high-density adaptive foam base. Without springs involved, support comes purely from how the foam responds to your body weight, which is actually part of what makes it such an effective memory foam mattress for pressure relief. It contours closely rather than pushing back, so weight gets distributed rather than concentrated at specific points. The cover is a breathable, skin-friendly zip design that's fully removable and washable, a genuinely useful detail if you want to keep the surface properly clean rather than just spot-treating it over time.

The Somnus comes in three height options, 18 cm, 20 cm, or 25 cm, so you can choose based on how much cushioning you want or how it needs to sit with your bed frame. Across all three, it carries a medium-soft feel, which is specifically suited to side sleepers. That's really the mattress's whole purpose: the plush surface cradles the shoulders and hips rather than resisting them, which helps take pressure off those areas and keeps the spine aligned while lying on your side, something firmer mattresses often struggle to do well. As a genuine medium soft mattress, it's built with a specific sleeping style in mind rather than trying to suit everyone.

You get a 30-night trial period to test the Somnus at home before deciding, with the option to exchange it if it isn't the right feeling for you. It's backed by a 7-year warranty, a strong length considering there's no spring system involved to wear out over time, just consistent foam support. Between the zero motion transfer this spring-free build naturally provides and a washable cover that keeps things hygienic long-term, it holds up well as a genuine pressure relief memory foam mattress, especially for side sleepers who've struggled with pressure points on firmer or spring-based options before.
