I ordered the blue bed frame but I received the gray instead. I didn’t mind it much even though I was so looking forward to having the blue frame, at point I settled for the gray since I really needed a bed and Customer service was kind and courteous enough to give me back 20.
The bed itself is good and the 3 stars is for one of the drawers that doesn’t fit in place since the metal guides is bent. 
Other than that, you can get away with a 12” mattress and no box springs. But if you want it to be higher off the ground, a 4”-5” box spring  12” mattress will do the trick.
