Sareer Matrah Reflex Plus Pocket 1000 Extra Long Mattress in a Box - Extra Long Single 3ft x 6ft6; 10cm longer than a standard single and offering traditional pocket springs, the Reflex Plus is an ideal choice if you are looking for a longer mattress with a quality support. Upholstered in a soft to touch fabric cover, it benefits from hypo-allergenic fillings plus reflex foam, a durable layer that will maintain its shape and density throughout its life. Totally independent pocket springs made up the foundation of the mattress with each one housed in its own cloth sleeve so the load on one does not affect any neighbouring springs. Their flexibility allows them to contour your body perfectly and provide piston-like support to each part of the sleepers body, resulting in a system that supports directly at the point of contact. Taking the mattress to your bedroom is effortless, as it is delivered vacuum packed in a roll. Once unpacked it will fill out to its full and permanent size within a couple of hours. Designed to be one-sided, it does not need to be flipped, but to get the best out of the mattress and enhance its lifespan, we recommend that you rotate it frequently. .
