Its comfy. Nothing to attach the mattress in place. I do like that the cover is removable so you can wash the cover or replace the inside of the mattress. Not happy with the colour. I ordered the “grey” on screen in looked like a light smokey grey, in person its more of a dark charcoal grey - almost black. Dont think this should be priced over 200$ I’ve had it for less than a week and sat on it for maybe 10hrs and its already flattened and the mattress fabrics loosened. I wouldn’t recommend.
