Works as you would expect from a waterproof mattress cover. It is comfortable.  It is very soft and adds the cushion to my new mattress. I haven't tried to wash it yet and hope it will maintain through cleanings.  It is warm and meets the expectations from waterproof mattress pad.  It's not like a regular mattress pad.  We tend to use it in cooler seasons, but it can be a problem in the summer.  Aside from that, I do like this matters pad, it fits well by bed, I do like the softness the quilted top.  I recommend it.
