I have in my living room, and spare room. I have 10 inch thick foam mattress on mine as I am disabled, extremely comfortable!
Great day bed. Easy to put together, properly labelled - it took my husband and I 30 minutes. I would suggest going with a proper twin mattress because the thin foam ones won't sit above the metal at the front which makes it awkward to get in and out of. Unfortunately, it went on sale a week after I purchased it ($60 off) but they wouldn't honour a price adjustment because it was a 'boxing day' sale. There is also the option to purchase a 4-poster bed attachment at the top which is really cute. Overall, great deal and great quality.
you really need 2 people to put it together but good frame
