Please pay attention to my review as I just put this bed together. If they gave you regular screws that you could use a screwdriver on, you could put his bed together in an hour. However, they give you an allen wrench which will make the process twice as long. But...the bed went together fine as many have indicated. Now, here's the tricky part...the distance from the top of the slat (where your box spring will set, or BUNKIE BOARD is barely 11 inches to the bottom of the headboard, which means that if you try to put a box spring under your mattress, it will end up too high and will bump into the headboard, which protrudes 2 and a half inches out into the bed area....which means your mattress will over hang the box spring on the end of the bed by a couple of inches. Not a great fit. So, if you use a box spring and mattress combination, you have 11 inches to play with. That's it. If you have a 4" box and a 6" mattress it will look fine, but in my case where my mattress was 10 inches high, I had to use a bunkie board so it all fit under the headboard. You will notice in the picture on Wayfair that although it says you must use a box spring, the picture shows the mattress on the bed WITHOUT a box spring...they used a bunkie board instead. That made it fit under the headboard without coming in contact with it and thus NOT pushing the mattress out from the box spring by a few inches at the end of the bed. So, no matter what you decide to do, you have 11 inches to play with and that's all. You'll remember this review when you don't follow what I commented on here. Good luck. It does look nice and all but the comments are from outer space. Look at the picture and see that the mattress does not use a box spring, but a bunkie board...and YOU HAVE TO use a bunkie board because the bed only has 3 support slats and cannot support the mattress without a bunkie board underneath it. The optimum word is 11. You have 11 inches to play with. Use them wisely!
