Great quality, packaging and everything included for assembly
By Dean W. Edwards Jr. on Reviewed in the United States on June 8, 2025
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.

good product but not for us
By Kayla on Reviewed in the United States on July 2, 2025
We have had this box spring for 4 years and have had to used the warranty once (may twice?) for pieces that would break. It has broken again (so either 2nd or 3rd time now in 4 years), so we are going to look for another product, more sturdy. Between the both of us, weight is around 600lbs or less. I think it is a good product but doesn't hold up our weight. I will say the warranty process was very simple when we used it. We located the part (the parts are labeled with stickers) that was broken and they sent it to us free of charge. It was a simple process and good customer service.
