I have 2 German Shepherds who love to sprawl on a comfy bed! I needed a new one, and have purchased Serta Pet Beds previously. Their product is very well made and supports a 90 lb  GSD without sagging. One of the Serta dog beds is almost 5 years old, and still looks firm. The other Serta is almost 2-1/2 years old and still holding its shape. I recommend this dog bed to anyone who is looking for a well made bed for their beloved dog!
