Keep your mattress as good as new with this Basic Mattress Underlay. The underlay fits neatly between the base and the mattress. The nubs on the back of the underlay guarantee the mattress will stay in place. The mattress underlay provides perfect protection, as friction between the mattress and the base of the bed caused by movement during sleep can often damage the mattress. So you can protect your mattress from pressure and wear. The mattress underlay is made from a durable fabric and creates a barrier between the mattress and the base of the bed for a good night’s sleep. Size: European Single (90 x 200 cm)
