The colour of these is absolutely gorgeous. It’s not aggressively yellow, or a flat tone, and it has some light heathering that makes it look more expensive. 
Comfort wise they are fine, nothing exceptional. We bought 2 so that we can push them together and make a double bed for guests instead of having a bulky futon. We will definitely use a foam topper for comfort- they are very, very firm and the cross bars can be slightly felt when laying down. 
My only small disappointment is the height . As a bed, it is very low to the ground. Our air mattress is literally higher. Expect to feel like you’re sleeping on the floor!
