Flexisleep Air-Lite Pocket 1000 Adjustable Bed Mattress - 3ft6 Large Single; Offering a medium to firm support, the Air-Lite is an ideal choice for those who prefer a comfortable mattress thats not too hard and not too soft. Generously filled, the mattress is upholstered in a soft knitted stretch fabric and combines body-contouring springs and a 60mm layer of Air-Lite Comfort foam. At the core of the mattress is a pocket spring interior; a sleep system made up of totally independent springs housed within their own cloth sleeve. This flexibility means the load on one coil is not affected by any surrounding springs, resulting in piston-like support to each part of your body. The perimeter is strengthened by the addition of a foam encapsulated border that offers edge to edge support and prevents the feeling of roll-off.
