Mayton 4.5-Inch King Box Spring Foundation - Easy Assembly, Sturdy Wood Frame for Mattress Support & Pressure Relief | Compact Design Fits Small Spaces | Bedroom, Guest Room, Dorm & RV Use (Black)

This box spring was easy to assemble and seems quite durable.I laid the 5 frame components on a flat surface for assembly and installed all the carriage bolts loosely at first. Then I quickly checked each inside corner with a small carpenters square to make sure I had the box spring assembled squarely before tightening all the bolts. If you don't have a square, you could use a hard sided box or other household item that you believe is fairly square (90 degrees on at least one corner). I also made sure each long side component was lined up nicely with each end component. If you bolt the side component down somewhat crooked (askew, tilted, etc.), it may make putting the cover on more difficult. I just lined them up by eye when performing my final tightening and all was well.The box spring came with a small stamped steel wrench for tightening the carriage bolts, but I think using a standard box wrench or ratchet and socket makes this much easier to tighten down. If you don't have those tools you could certainly use the wrench they send in the hardware kit.Once the five frame components were tightened down snugly, I laid out all of the spring boards into the slots provided on the side frame rails. Then I screwed them down to the frame with the provided wood screws and my cordless drill. You could use a #2 phillips head screwdriver, it would just take a bit more time, and you'll get a good arm workout.Last, I installed the provided cover. I noticed some folks said it was hard to get installed in the comments. I had no issues at all, similar to installing a fitted sheet over a mattress. I think making sure the components are mostly square and installed lined up, will make this part easier. There was a draw string type device that I could pull tight around the "skirt" of the cover once it was installed. This ensures that the cover can't easily slide up over time.We installed this under my daughters Full XL memory foam style mattress and it was quite sturdy and did not creek or make any noise when in place.
