The sheet is made of soft velvet in white or blue colour. The sheet has a special foam layer which prevents the velvet from rolling on the mattress. The self-adhesive function makes it possible to attach the STABILObed® cushions to it, which prevents them from moving as most cushions have a VelcroFit™ system. An elastic trimming keeps the sheet in its place. It is also possible to make custom-made sheets with non-standard dimensions.
