ZINUS 9 Inch Metal Smart Box Spring / 350 lbs Mattress Foundation/Strong Metal Frame/Easy Assembly, Twin

I bought this because a traditional box spring would not have fit up the staircase in my home due to a hair pin turn. I thought that I would be sacrificing structural integrity by buying this, but I was wrong. This thing has been very sturdy. I actually fell on this full force on the ground and it did not budge ( I'm over 300 lbs for reference.).. Another issue I thought I would encounter was squeaking. To my surprise they have added foam to the connections to prevent this and it has worked for almost a year so far. Also I thought with all the Allen key components it would be difficult to assemble, but the ratchet Allen key that they include makes it very easy to assemble. The has also proved versatile for other projects If you don't have the space to bring in a full queen box spring for whatever reason, rest assured that this is a good solution for you.

Lo pedí hace unos meses y me pareció un buen producto, sólo que me equivoqué ya que mi cama quedó muy alta. Lo debe haber pedido de menos centímetros. Lo ensamble yo sola y me fue bien

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.

Bought this a few years ago and still love it to this day. It's lightweight and when moving it's perfect as it can be taken apart and put back together.

These box springs are light weight yet incredibly sturdy. It is so easy to put together it literally only takes about 10 minutes. We liked this box spring so much we have not purchased them for other bedrooms in our house. It is sold at a very reasonable price point. One of my sons is a 6'3" rugby player and multiple wood box springs had broken under his mattress but this one has held up for years now. Highly recommend!
