The product fits perfectly to the mattress. I recommend buying it when buying a mattress.
Well made and sized fitted sheet. Also keeps the Tesmat together. Recommend.
The fitted sheet is a great breathable material and it works great at keeping my mats from sliding apart as they kind of try to do sometimes without it. Definitely get one if you’re buying the mat!
Used it once so far and was great. We have a 1 year old and she slept well.
