The natural Wool 600 Dual Layer Hybrid Mattres is not your typical budget mattress. This Pro Hybrid Mattress features a premium Bonnell spring system with a unique 2-layer Eco Foam construction and an extra layer of 100% British wool. It is a Bonnell sprung mattress with medium firmness. The mattress measures approximately 20cm in depth. To make this budget mattress more comfortable, we have doubled the amount of eco foam fillings and then wool which alongside our high tech sleep surface provides excellent temperature regulation keeping you cool in summer and warmer in winter. This affordable 8 eco mattress uses eco foam which is made from 100% recycled foams making it an environmentally sound filling option, together with an open coil mattress structure it helps to actively support the bodys key pressure points. Our Dual Layer 600 Pro Hybrid Mattress has been manufactured in the UK. This eco mattress is vacuum packed and rolled for easy shipping, reducing the environmental impact of transportation. As the mattress is rolled, it also makes for easy transport to bedrooms that are harder to access.
