I spent a lot of time researching different bed supports and poring over reviews before settling on this one, and it seems that I made the right choice. Five years ago, my husband and I purchased a very nice wooden four-poster bed, but unfortunately it has not held up well under the weight of our very heavy queen-size memory foam mattress. The bed design attempted to support our mattress (and us) with just a single center leg on each of three flimsy metal slats. The whole bed creaked horribly and the side rails had begun to bend and bow.I bought this product with the idea that I could seat it inside my wooden bed frame, without actually being attached to it, to support the mattress so that the wooden frame would no longer have to take the weight and could basically be decorative, and it worked beautifully.My biggest worry when buying this product was that the measurements wouldn’t be exact. This steel frame measures exactly 80 x 60, which was perfect because I only had about an inch of extra wiggle room within my wooden bedtime to fit it.Assembly was quite easy. I actually partially assembled it in the living room where I had room to work, so that I could measure the finished dimensions and confirm that it would fit inside my bed. Once I knew it would, my husband and I were able to fold it up enough to fit down the hall and into the bedroom, before unfolding it in place and adding the center support and slats. It was incredibly simple. Removing the existing flimsy metal slats from my old bed took longer than assembling this new one.I’ve seen some reviews claim that the center leg is too short. When you first unfold and place the center support it sort of seems like the center leg is a little shorter than the others, but once you put even a tiny bit of weight on the center support, it pushes down into its proper position.I also have not noticed our mattress sagging down between the slats at all, even with my husband laying in the bed, I can look underneath and nothing looks strained by the weight.As for marital activities, the bedframe has held up and there is NO squeaking. We have hardwood floors and it does move along the floor (basically bounces around in the one inch or so of extra space it has within the wooden frame surrounding it, which does not move). Without sometime in the way to stop it from moving however, I could potentially see this bed walking its way across a smooth floor. Placing the bed on top of carpet, an area rug, or putting some kind of rubber (such as shelf liner or similar) under the nine legs would probably help with that though.Overall, this bed support was a great purchase and well worth the price!
