Flexisleep Gel Hybrid Medium Pocket 1500 Adjustable Bed Mattress - 4ft Small Double; Upholstered in a soft micro quilted stretch knit fabric, the Gel Hybrid 1500 mattress combines body responsive pocket springs and cooling Gel-Flex. A temperature regulating and pressure relieving material, gel-flex is located below the outer cover and is designed to offer a cooler nights sleep. The core of the mattress is made up of medium support pocket springs, with each one tightly nestled together and housed in this own cloth sleeve. Each spring is totally independent of any neighbouring springs, resulting in a system that offers piston-like support to the neck, hips and lower back. The spring system is encapsulated in a high-density foam border that adds strength to the perimeter of the mattress, offering edge-to-edge support.
