"I had considered memory foam, egg-crate foam, etc. beds for my arthritic 12 y/o German Shepherd/Chow mix, and after reading the positive reviews on this bed and seeing the low price, I ordered it for my her. We've had it for a month now and everything is perfect (structure, cover, thickness, support), except I wish it came in one size up. With larger dogs prone to hip dysplasia I'm surprised it's not made in a larger size. When my dog stretches fully out, her head hangs off the end. Still, she loves the bed and took to it right away. I placed her old one next to it so she could choose, and she's slept on the gel bed every time. I've just kept her old bed there as a head support. The bed is well-made, and soft but supportive enough that she can push herself up. I didn't want a bed that was so soft or mushy that she'd get her feet caught up in the bedding while trying to get up. Superb orthotic bed at a fantastic price."
