ZINUS Luis 14 Inch Metal Platform Bed Frame with QuickLock System & Steel Slat Support - No Box Spring Needed, Easy Assembly, Twin Size, Black - Perfect for Dorm Rooms, Guest Beds & Small Spaces

After perusing many reviews for a queen platform, I decided to go with the Zinus 14' metal platform bed. The assembly was simple and took about 45 minutes at a leisurely pace. The instructions show pictures; there is no written explanation. I did not find this to be a problem. You begin with the 4 corner pieces, bolting them to each side rail, and then to the front and rear. After that, you bolt the center legs to the 2 sides. Then you attach the legs to the center beam, then bolt the beam to the front and back. The last step is to pop in the metal crossbeams. I had to start each end into its slot by going back and forth evenly. This might be accomplished more easily with 2 people. In the end, they pooped in with no problem. The package provides one extra each of the 2 kinds of allen-wrench screws. There were two wrenches included, one for each size. A few of the holes didn't line up exactly, so that the screws had to be started at a slight angle, but they soon straightened out just fine.An earlier reviewer complained that the mattress slid around, because there's no lip around the edges to hold it in place. Apparently someone at the company was listening. Four of the cross-slats had peel off strips revealing adhesive. These I distributed evenly. So far, there's no slippage. When the adhesive wears out, I'll just get some 2-sided tape and cut it into strips. The combined weight of my partner and me is 360 lbs. The bed is even and solid with no squeaks and is fine with boisterous activity, although the unit did scoot across the floor a bit. The legs on mine are smooth on the bottom and do not seem to scratch my hardwood floors, though I will probably put something under them anyway. The unit is easy to slide for cleaning underneath. All in all, a good deal. Who needs box springs? My mattress sleeps just fine without them. A final note: I would say my mattress feels slightly firmer on this platform than it did on the box springs. Also, watch out for major toe-stubbing if you're not used to legs on the side of your bed!
