Mainstays Quick Lock Steel Support Indoor Daybed, Twin

The parts are numbered. 1 goes with 1, 2 goes with 2, 3 goes with 3, etc. It appears to be very sturdy and I didn't experience any problem assembling. You don't need extra tools. My tip is, when you get to the slats, if you have a problem placing the clip in on any of them, be sure to look at the slat. The slats all have a notch at both ends underside. Make sure the notch is in the base bar. If the clip is a little tough to slide in, press down with some weight on the base bar, after making sure the slat is in the notch. They all went in easy for me except for a couple and one I noticed I did not have it in the notch and the other the clip was stubborn and I pushed down on the base to give room for it to go in. I noticed it appears to be made by Zinus. I had ordered an 8 inch Zinus mattress that I had a difficult time getting the box open but finally did. I like the Zinus mattresses and have purchased several over the years. I don't think you can beat this price for an all metal daybed. There is some extra parts included but I did not need them and I didn't need the included hammer either.
