The daybed is so well-priced and is beautiful in person..took my husband a couple of hours by himself to put together but not difficult. I bought a ten inch mattress on wayfair which works well, especially because it leaves just enough space to tuck in sheets and blankets around.  Bought a twin blanket but maybe could have used full given it doesn't come all the way down on both sides, also used a queen fitted sheet but probably could have used just deep pocket twin if I had it.  Added a couple of pics so you can see what it looks like from front and side (how deep it is).
