A Micro e-Pocket mattress contains a core of individual springs, each resting within their own fabric pocket. This allows each spring to move independently which enables the mattress to adapt to the subtle contours of your body, for even more support and comfort. All Jay-Be® Micro e-Pocket mattresses have e-Fibre comfort layers which offer recovery and support like foam but unlike foam, e-Fibre is free from Volatile Organic Compounds (VOC's), odourless and hypoallergenic. Furthermore, the unique open cell structure of e-Fibre comfort layers allows air to flow through the mattress which reduces moisture build up, thereby creating a drier, fresher and more temperature ambient sleep environment.
