Although the memory foam in this bed seems good the zipper on the cover broke the first day.  Thankfully, Wayfair made good on the situation as the bed is useless without a working zipper for the cover. In addition, the cover is flimsy and not substantial enough to  hold up to my dog's thick nails. The material is already punctured on the replacement cover in less than a week just from normal movement on and off the bed. My dog's nails are trimmed regularly and she is not rough on it. Now finding a decent  replacement cover for a dog bed of this size will be expensive. So, do buy a dog bed from Wayfair as customer service is great but beware of this one as the cover matters.
