The Spinecore Firm Plus Activecool Mattress is built for sleepers who need a harder base with higher density support, specifically engineered to be good for the spine. It combines a luxurious memory foam quilted top with a firmer, denser support structure underneath, giving you cooling comfort on the surface without sacrificing the firm backbone support underneath.

Three Layer ActiveCool Construction

The mattress is built with three key layers: NASA-developed memory foam with ActiveCool technology for the comfort surface, a Premium Comfort Foam Layer beneath it, and an Extra-Dense, Pure High-Resilience Foam support layer as the firm base. This gives you the "soft-on-top, firm-underneath" feel that's specifically engineered for spinal support.

Harder Base, Better for the Spine

Unlike Wakefit's softer Plus-series mattresses, the Spinecore Firm Plus is positioned specifically around a harder base with higher density — designed for people who need extra-firm structural support rather than plush sink-in comfort.

Premium Quilted Cover

The mattress is wrapped in a High GSM Melange premium knitted fabric cover with memory foam quilting on top, giving the surface a soft, luxurious hand-feel even though the underlying structure is firm.

Usability

It's recommended to use with the memory foam side facing up for the intended ActiveCool comfort experience, though the mattress can be used on either side depending on your firmness preference.
