Arrived in great condition. Assembly instructions were very clearly illustrated and the Individual pieces were clearly marked. The frame fit very well and seemed well-built and durable. Have had no issues with the frame bending or making any noise. Very satisfied with a very reasonable priced purchase.

I was very surprised by its good quality. Thick, highly sturdy material and the assembly tools were included. Easy to assemble. Does its job perfectly. It saves you a lot of money because it makes it unnecessary for you to buy a boxer, which costs over $400. This thing supports and protects the mattress! Amazing

A convenient way to replace a box spring. I hadn't bought a mattress or box spring in a long time. When I started looking I was surprised that something like this even existed. It went together pretty easily and seems pretty sturdy. I just wished it was as easy to drag my old box spring down to the dumpster as it was to carry this one up to my apartment.

So easy to put together, but honestly had someone do it who had done it previously. Well made, what a difference when setting it back on an antique brass bed on top of angle iron (got heavy duty pool noodles to cushion it and zip tied them on), so no slippage. Mattress is now at a decent height. BUT AFTER A WEEK THERE IS A BIG DIP IN THE CENTER! No way that stands up to even 900lbs., claims 3,000lbs. Had to fix it with a 4" x 4" block of wood cut to lift up the center, put felt on the bottom to not scratch the oak floor. ONE MUST PUT IN A HOMEMADE SUPPORT IN THE CENTER. It is only a double, for a queen or larger, consider two. NOT WHAT I EXPECTED.

The iron used in the construction of this box spring is very well made. The instructions on how to assemble the box spring came with the package. The rails were marked with labels for ease of assembly. The print on the instructions could have been darker to make them more legible but if you look closely, you can see the letters of the parts at each step. In the photos, you can see the letters. The assembly of the center cross was the most difficult, which is why I took a picture of it. When complete the box looks good but move it by holding the outer perimeter. I used a battery powered drill and socket wrench to make the installation go faster. The cover fits over the top. The bottom is not covered. It took me about 2 hours to assemble.

Hardware: Excellent. This manufacturer has a clever way of guaranteeing they ship the right hardware. They blister-pack the hardware and specifically label the extra parts. If you are missing a part, you caused the problem. Tools: Poor. The manufacturer includes 2 sad, disposable wrenches and no hex wrench. If you have a miniature, metric socket set, I believe you could fly through the installation. Assembly: Excellent. After I assembled the center cross, I was free to assemble this in any order. If you have some room, assembling this away from the bed would speed the process. My space is limited, so I assembled this box/foundation/platform inside the confines of our bed frame and that was manageable. Tightening the nuts takes far longer than assembling the sections. Sturdiness: Good. All holes lined up properly as did the threads of the integrated nuts. The welds seem complete and placed correctly. The manufacturer does not use lock washers and nuts; instead, they apply thread-locker to the bolts. I do not know about the durability of this solution yet. The entire product is made of light, square tubing. It feels like you could break every part of it over your knee, but the structure becomes strong when you combine the parts during assembly. Rating: I give this a 4 because nothing strikes me exceptional about the product. When I opened the box, I found half the zip ties severed, but all parts were present. Someone adhered the Velcro for the cover onto the sections, which was odd because the directions indicated I would have to perform that step myself.

Super solid. Perfect dimensions. For a foam mattress you'll also need a Bunkie Board for proper mattress support as I did. All good.
