Anchor Support Foam Extra Firm Mattress – 20cm Extra-Firm Orthopaedic Support

Need the firmest possible support? The Anchor Support Foam Extra Firm Mattress is our hardest mattress, built from a 20cm reflex foam core — 40 density for an extra-firm feel — that delivers maximum orthopaedic support, exceptional resilience and proper spinal alignment. Silent and spring-free, with a soft removable quilted cover, it's made for adults who want a very firm, supportive surface, heavier sleepers and anyone who finds standard mattresses too soft. Hand-made in the UK and delivered rolled.
