Don’t waste your money! I bought a jumbo one for my 14 year old Golden who has cancer. I figured it would be good because the description said “The crushed memory foam comfortably conforms to your pet’s body to provide an extra supportive sleeping surface” But sadly, the crushed memory foam is in cells or columns sewn into the bed and it bunches in one place. I’ve pushed it around and evened it out - but no matter what I do - she is still essentially laying on the floor! My poor pup. I’ll get her something else. Don’t bother spending your money on this!
