I tried and returned 2 other more expensive orthopedic beds before buying this one. This was the only one of the 3 that actually gave comfort to my 24 pound 9 year old shih tzu. As you can see, she passes out on it very comfortably! It is very thick but gives just enough to provide comfortable support. It does not sink to the floor like most beds do. She appreciates the bolster as she uses it as somewhat of a pillow. I like that the cover is pretty thick and easily removeable and washable. It is a very heavy thick bed, lots to it for deep support. It took almost 2 days to fully fluff up. It's so comfy my cat has also decided she likes it better than her bed! Lol (she is balled up in the 2nd pic!).I was really worried about the underside having a mesh like bottom but my fur kid doesn't move her bed at all. If you have a chewer that may flip this heavy bed over, I wouldn't recommend as you can see the mattress but it would take quite a bit of work to flip over.I wouldn't say it is chew proof, there's always a chewer out there than can destroy everything but as far as MY shih tzu who is not a chewers, this bed is wonderful in all aspects for her!I had doubts about this bed because the price was low, but it’s name brand, and the reviews were great. However, it was an excellent purchase. It’s definitely bigger than I expected. Our giant sleeps on a medium. He actually laid down on it before I even got it out together, which was an easy process. I’d happily recommend this bed. It’s solid, nice, easy to clean, and loved by our big, fluffy boy.Great product for the price. We have a nice orthopedic bed in our room for our 13 year old Border Collie. We wanted one that we could bring on travels with our dog. It will also double as her living room bed. It’s a great size and aesthetically pleasing. It will come rolled up in a box. I highly recommend letting it sit out to “puff up” before putting it in its cover.My pets love this bed! I would recommend washing it first as it must arrive with an unfamiliar smell- this caused one of my dogs to attempt to “ mark” it as her own in excitement when it first arrived. This led me to washing it, which was an easy task. Keep in mind this bed it massive so be aware of the space you will need for it. My older pup ,who I bought it for, really loves it though!Ace loves it! He hasn’t gotten up. He’s about 70-75 lbs and I bought the medium bed for him. The mattress is one piece and then the nest part is a separate piece with its own zipper on the inside to keep it in place. It’s got a no slip bottom. It’s well made and seems like it will hold up.Hey Sealy! How’s this for an endorsement? Unboxed the dog bed to allow it to fluff up. 2 of my 5 dogs thought it was more comfortable than the other 7 beds in our house before it even was a “bed”!While he is a bit reluctant to change, once he figured out this was his new bed he absolutely loves it. It's BIG and soft..spends more time in the bedroom now than his other bed in the living room!Vraiment magnifique! Facile à assembler. Protection contre les fuites sur tous les coussins. Housse facile a enlever et laver. Une qualité qu'on voit rarement sur des coussins de chien! Bonne épaisseur pour un grand confort. Un coussin qui a rendu mon chien heureux! Tellement satisfaite de mon achat que j'en ai commandé deux.My big pup loves his new bed, easy to clean and the eddges are zipped up so u know they wont fall to the side like most other dog bed. Once u get the bed u need to wait 2-3 days so it expand to the full. This bed is great and large but the inside feels like shredded foam i expected it to be a foam matresse like other ortopedic beds.Great size! Material is durable, and easy to wash. We bought for our 60 lb border collie rescue, however our Westie poo and our 13 year old stole it from the poor guy before he even had a chance. This bed is well worth the extra cost for other comparable in size.My Freya loved it and sleeps on it nightly or any time of the day when she feels like it. Definitely worth the money spent on buying this huge mattressGreat bed
