good quality, well made  Our 97 pound senior lab did not try it for several days.  We keep it in the office where my husband is approximately 4 to 5 hours a day and now our lab lays on his new bed.  He won't sleep there at night, he has his favorite quilt for that.  He does have hip and joint issues, so I'm hoping the this helps his condition.  The white top material does wrinkle, a different color would probably be better to not show the fabric wrinkle.  If you want a "smooth" appearance on the top layer, you probably won't like this one
