Great daybed that converts to King for guest. We have it in the spare room and it leaves room for me to do yoga, takes up a twin bed space only. We bought two 6.5 mattress, two 8 mattress would be too high as the length of headboard to bed is only 13 so two 6 mattress works great as you can stack the two twin bed and no need to store the extra mattress separately. Its been comfortable to have day naps on it. Took 5-6 to assemble, not hard just plan for it and lay everything out first. Quality is good, it does make a bit of sound when we first sit but doesnt bother us. Havent used for King much but looking forward.
