I knew there were going to be a lot of parts, so I decided to be as organized as possible. After opening the box, I marked each group of items with a sticky note to make assembly as easy as possible. It took 45 minutes total to label, assemble, and put the cover on. I especially loved the mini ratchet tool that was included; it made tightening everything much faster and easier than using a standard allen wrench. Everything fit as expected and was easy to move into our rolling adjustment frame. The King mattress fits nicely on the metal box spring and does not slide around at all. It looks great and feels very solid. We are looking forward to having family visit and hope they enjoy the comfort. If you take the time to organize the pieces first and use the provided ratchet, this is a very straightforward and high-quality setup

This product is great, I am 100% satisfied with this purchase. I am using this box spring with a Nature Sleep memory foam mattress. If you have an innerspring mattress your mileage may vary. My review as follows will cover several different aspects of this product and why they are great. Portability: Who knew you could assemble a box spring instead of lugging around a 50+ pound bulky wooden frame? Once assembled, the frame is lightweight and much easier to move around than a traditional box spring. The next time I move I am just going to take it apart instead of it taking up space in the moving truck, very economical in that sense. Assembly: Assembly was very easy, no mechanical inclinations required from the assembler. The set comes with an allen wrench/hex key and you use that to hold bolts in place while you tighten wingnuts with your fingers. Please ignore any reviewer of this product who said it was too difficult to assemble, took too long, or had confusing instructions, they are either lazy or completely incompetent. It took me about an hour to assemble by myself, and it would have taken even less time if I hadn't been half watching TV and drinking a beer while I was putting it together. The instructions aren't written words, but pictures showing which pieces to assemble with which bolts, but if you ever built a Lego set when you were a kid you should be able to handle this. It is easy to tell which pieces should be facing up during assembly, because most have a 'this side up' sticker. The pieces that don't, it either doesn't matter which side is up or you can tell which side should be up because of the notches the slats will fit into at the end. The Cover/ Looks: The zip cover looks nice and the white sides are a soft plush. Make sure you sweep your floor before zipping the cover on though or you might get dirt all over the nice white part. Some people said that the cover ripped when they were zipping it up, that was not the case for me. The cover is a very tight and perfect fit, but the white sides stretch. So when you zip it on, don't just yank on the zipper as hard as you can, pull up on the white parts that stretch and it will make the zipper easier to close. Durability: It seems sturdy enough to me. I have had for two weeks, no complaints. I have unzipped and re-examined the frame and it has not bent or buckled under the weight of two people or any vigorous activity. Could you bend the metal of the frame after you put it together? I guess you could if you tried to, but why would you do that deliberately? Putting a mattress on top of it and using as intended should leave you with no issues. I hope this review provided all the information needed to help in your purchase decision, and I am sure you will be satisfied with this box spring.

Super easy to put together, sturdy, and fits perfect. It’s also light enough that I could drag it to the bedroom after putting it together and I’m pretty weak lol

Purchased this box spring years ago and the initial build was simple and easy enough for me to build alone. I never had issues with noises or mattress sliding on it. It was sturdy and maintained its sturdiness over ~5 years. I took it apart today and was surprised to see the screws looked great after being removed. Would purchase the product again next time i need a new box spring.

Loved the fact that it arrived in a compact box making it very manageable to carry through the house and into the bedroom as I have a very small and constricted floor plan. Upon opening the box it seemed a bit overwhelming but once I looked at the instructions and the diagram of the labeling of the pieces I was very impressed with how easy it was to lay out and put together. All the hardware fit smoothly and was easy to put together using only the tools that were supplied. That in itself was a touch of class, to be provided those items and not have to find and size up my own tools. The quality of the hardware as well as the packaging was well thought out and I appreciated the extra nuts and bolts. I actually used the extra nuts to double nut the two long bolts that secured the middle cross members together in the center of the box to ensure they don't work their way loose over time. The nuts and bolts looked to be well made and the shouldered and serated locking surfaces of the nuts weren't lost on me. That was a great selection of fasteners. The bolts were made very well and the heads did not ring out or become deformed from being tightened and kept their integrity and shape so as to be removed for disassembley in the future if needed. All the frame work pieces had a very nice finish to them appearing to be powder coated. The final addition of the frame cover was an added item that enhanced the overall quality and appearance of the total package once it was fully assembled. Total assembly time was no more than an hour by myself and being put together on and inside an existing raised oak bedframe with large headboards and side rails. Very pleased with this excellent product and would most definitely buy again and recommend to others looking for a similar item to fit their needs and lifestyle.
