A fantastic support system for your body through a combination of individual pocket springs and memory foam. Pocket Sprung mattresses are the best you can buy in terms of quality and comfort. The pocket spring system is encapsulated in layers of high-density support foam, and the cover features stitched bound border support. This means no 'rolling off' - you can enjoy the full width of your mattress without it sinking in at the edges! The combination of individual pocket springs topped with a sumptuous dense layer of pure memory foam means that this mattress offers a high level of individual support and comfort by adapting perfectly to the shape of your body. Pocket springs move independently to support your body, whilst the memory foam moulds to your body shape and takes pressure off the joints & adds comfort. Note: As our mattresses are vacuum rolled, we advise 72 hours for the mattress to inflate to its full depth. Does not need turning like traditional mattresses. Roll packed for easy handling & manoeuvring up the stairs! Medium-firm rating > recommended & suits most sleepers. Made using high-quality materials to give you a great night's sleep years to come. Heat and pressure sensitive. Soft quilted breathable cover which promotes air circulation. Hypo-allergenic / anti-dust mite / sanitised fabric. SATRA Tested & certificated. **Please note there may be slight differences in the cover design and features pictured due to changes in supplier materials. **What's Inside? The pocket spring system in the middle is the main business centre of this mattress. The pocket springs are fully surrounded by high-density support foam to create more layers of comfort and support. The top layer is pure memory foam which is wonderfully squishy for added comfort. (Please bear in mind if you zip off the cover to check out the contents, you won’t see the spring system as it is fully encapsulated in foam! This is just the cross-section).
