The FirmCore Plus takes firm support to the next level. Two layers of high-density foam on top of a pocket spring core means this mattress is built to stay firm, stay flat, and stay supportive - long after cheaper alternatives have given up.
What This Product Is Good For
- King single bed setups
- Bedrooms and guest rooms
- Sleepers who prefer a firm feel
- Rooms needing a 203cm mattress length
Why This Is a Smart Choice
- Dual high-density foam layers - more resilience, longer-lasting shape retention than single-foam designs

- Two-layer foam construction is the key upgrade over the FirmCore Classic
- Soft-touch knitted cover - breathable and gentle on skin
- Firm comfort level - holds firm through years of nightly use
- Total height 25cm - deeper profile for a more substantial sleep surface
