I bought the XL bed for my Catahoula/Great Dane mix and the medium for my Standard long-haired Dachshund. They arrived rolled up wrapped in multiple layers of plastic. Easy to unwrap and quick to fluff up to size. The xl bed was sturdy enough to support ME without sinking to the floor. Both of the dogs immediately jumped on and were comfortable side by side so there’s more than enough room. No bunched up fabric very smooth easy to vacuum or wipe with a cloth. I am so pleased with this item. It’s investing in the health and wellness of your dog and undoubtedly the last dog bed you’ll ever have to purchase. So relieved to have a quality product for my pups...we’re all happy!Update: Jan 2021 still super happy with these beds- I’ve bought three of them- no seams tearing or loose threads, have washed the covers probably four times already and they’ve held up and didn’t shrink! My dog digs before she lays down, sometimes pretty rough, I was worried the cover would tear but NOPE! I am so impressed by this quality bed I tell everyone who is looking for a dog bed.... I’d probably even go as far as to recommend it for a toddler...the mattress really supports you, occasionally I’ll lay on the bed playing with my pups and it is so comfortable, most importantly you don’t sink through to the floor. To say I’m impressed is an understatement.*UPDATE* 10/2023 my dog’s digging finally tore up the plastic liner of the bed but the cover has held up beautifully wash after wash. I recommend zipping it closed while washing. I used duct tape to close up a few tear marks on the plastic liner and it’s holding up lol. Like I said previously I bought two of the xl beds one of the zippers gave out and got stuck closed so I can’t wash it anymore. I have a washable blanket over it and it’s been working just don’t want to spend the $75 to buy a replacement rn, eventually I’ll get one. But other than that I am still so happy with this purchase it is the best dog bed ever and my dog loves it!!!!
