My pup loves this bed! He is 92 pounds, and I was debating for a few days between the XL and Jumbo size. I read a ton of reviews before buying, so I know how important this is! I went with jumbo and I'm glad I did. It is huge, like some of the reviews said but my dog loves to stretch out when he sleeps and he fills up pretty much all of the jumbo. I think it's important when you're deciding on a size to not just think about the weight, but also the length of your dog, his arms/legs and his sleeping style. Does your dog curl up or stretch out? Although my dog doesn't typically like resting his head on top of a pillow/bolster he loves to have one there to rest it next to. He is 3 yrs, and had a knee injury earlier this year, so I wanted to make sure there was enough room on the platform for him to lay comfortably. Plus, I anticipate him having a doggie roommate/friend sometime in the future, and there's plenty of room for him and his future BFF to cuddle.
Only drawback was trying to get the liner over the memory foam- it was a work out! If it had more zipper all around the liner that would've helped.
This is a quality bed at a decent price and I 100% recommend it. The memory foam is thick and my dog seems extremely happy with it. He is literally snoring next to me on his new bed as I write this.
