Product Description

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

  • Queen bed setups
  • Everyday bedrooms
  • Guest room queen beds

  • 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
