I bought 2 of these beds, one each for my 11 and 12 year old boys. They love the beds. The desks and the little hideout area underneath tie for their favorite. I actually ended up buying shaggy runner rugs, size 2x6 foot to go underneath. That size actually fits perfectly between the wall and the dresser. 
As for quality, for the price, they seem great. I’m glad we got these beds.
