The quality and appearance of the mattress is excellent and we were most thrilled that it lived up to its advertisement of being super easy to vacuum off any fur! So much easier to remove fur from than any bed he's had before. I thought it was confusing that the small size is indicated for dogs up to 30 pounds but when you watch the video on the website it says a dog that is 26 pounds should have the medium size. We got the small to go inside his crate but in the future will likely also get a medium for out in the living room as he does like to sprawl and sleeps in a lot of different positions.
