The Cor Lapius is built entirely from high-density rebonded foam, no springs, no memory foam comfort layer, just a solid, dense foam core designed for maximum support rather than plush comfort. That's really the point of an ortho foam mattress like this one. Rebonded foam is denser and firmer than standard foam, and because there's no spring system to sag or wear unevenly over time, it holds its shape reliably even under regular daily use. It's built as a flat, reversible mattress too, so you can rotate it periodically to keep the firmness consistent across both sides.
Available in 15 cm, 20 cm, or 25 cm heights, this is the only mattress in the range with a genuinely extra-firm feel rather than medium or medium-soft. That firmness is intentional and specific: it's meant for people who need strong, unyielding support, often for ortho or therapeutic reasons, or simply because they've found softer mattresses leave them sore. As a proper extra firm mattress, it distributes body weight evenly across the surface without letting the hips or shoulders sink in, which particularly suits back and stomach sleepers who need their spine held in a straight line through the night.
You still get a 30-night trial period to test the Cor Lapius at home, with the option to exchange it if the firmness isn't right for you, even though this is a more specialized mattress than most in the range. It's backed by a 3-year warranty, and because there's no spring system involved to break down, that warranty reflects a design built for consistency over the long term rather than plush comfort upfront. If you've been told you need firmer support, or you've simply never gotten on with soft mattresses, this rebonded foam mattress is a practical, no-frills option built specifically for that need.
