I have purchased many dogbeds as both of my Miniature Schnauzers are 11 years old. This Dogbed4Less is made with memory foam and is an orthopedic bed with a microsude cover. I decided to purchase this bed even though it was more expensive than I wante to pay for it. But since both my dogs are getting old I thought it might feel better to their bodies when sleeping. Both of my dogs love the bed and it holds it shape wonderfully. In fact I have washed the cover on a regular basis and when I put it back on the bed looks new. The memory foam is cooler in the spring and summer and reacts to their body heat and weight which the memory foam can become warmer i a few minutes for support and comfort to your dog.nd reacts to body heat and weight, allowing it to mold to a warm body in a few minutes for the best orthopedic support and comfort. I have the extra large bed whih is 40"x35"x4" because my dogs sleep together. I recommend this bed for older dogs especially.
