This foam encased pocket spring mattress contains individual responsive springs, all housed in separate fabric pockets. Each spring absorbs and spreads weight across the bed to give you support and pressure relief for a comfortable night's sleep. The springs work independently to eliminate partner disturbance and eliminate roll-together. Layered with latex rubber and topped with NZ wool that adapts to keep you cool in summer and warm in winter. The foam edge support eliminates that feeling of rolling of the edge of the mattress, this means you can maximise the entire width of the mattress.
