No more tucking-in other mattress protectors or stripping sheets. When wet just use regular wash and dry cycle! On the go? Pack it up and take it with you. The big difference? PeapodMats lie flat ON TOP of sheets with a grippy material underneath that allows the mat to remain stationary and in-place WITHOUT flaps, straps or Velcro. This means there is no need to tuck or wrap the mat around the mattress or mattress corners. With the design of the PeapodMat, not only does it remain stationary, but will stay flat without bunching or gathering. This provides a comfortable and protected sleep throughout the night.
