Ordered the 5" Queen size. All parts were there. Assembly was easy, parts fix fine with no need for "tuning" anything. Appears to be very sturdy and I don't see the possibility of anything warping like may happen with wooden parts. We have a wooden bed frame that this fits on/in and because this is metal it slides a little. I'm going to add some "Allagator" tape (where one side of the tape is like a heavy gauge sand paper) to the metal frame which should stop it from sliding. So far I would recommend this.

The box spring arrived safely in dismantled format. I was concerned a little bit at first, but after carefully studying the directions, I was ready to assemble it. Very clever and sturdy design. We used it to replace thicker box spring. This new one lowered the height by several inches, making it much safer for an elderly person to get in and out of bed, which was my goal. Nice job, ZINUS!!

I purchased the ZINUS 5 Inch Metal Smart Box Spring over two years ago, and it has proven to be an excellent investment for my bed setup. Here are my thoughts on this product based on my experience: Pros: Easy to Assemble: The assembly process was incredibly straightforward. The box spring came with clear instructions and all the necessary tools, allowing me to put it together in about 30 minutes without any hassle. The parts fit together perfectly, making the entire process smooth and stress-free. Lightweight: Despite its sturdy construction, the box spring is relatively lightweight. This made it easy to maneuver and position in my bedroom. It's a great option for those who might need to move it around or set it up alone. Durability: After two years of daily use, the ZINUS Metal Smart Box Spring is still going strong. There has been no noticeable wear or tear, and it continues to provide stable and reliable support for my mattress. The metal frame is robust and shows no signs of bending or sagging. Design: The 5-inch height is perfect for those who prefer a lower bed profile. It provides ample support without adding unnecessary height, maintaining a sleek and modern look. Cons: Aesthetic: While the metal frame is functional and sturdy, it might not appeal to everyone aesthetically. However, since it's typically covered by a bed skirt or mattress, this is a minor issue. In conclusion, the ZINUS 5 Inch Metal Smart Box Spring has been an excellent choice for my bed. Its ease of assembly, lightweight nature, and lasting durability make it a standout product. After two years, it continues to perform just as well as it did on day one. I highly recommend it to anyone in need of a reliable and straightforward box spring solution.

Before I get into the review, it's important to know this product is NOT a box spring. It's a metal foundation. There is a difference between the two. You can Google it for more details but the traditional box spring actually contains spring coils similar to a mattress. The purpose of the box spring coils is that when paired with a mattress, it works to take in some of the shock from normal use, as well as serve to help limit any undo wear to the mattress. So with that said, this product is a FOUNDATION, not a box spring. Now that we have the product clarification out of the way, now for the actual review. Our soon-to-be 3 Y.O. has been sleeping in her toddler bed (converted from her crib) and thought it was time for her to move to a regular bed. She is potty trained and we decided there's really no reason to keep her in the toddler bed. Luckily our crib is a 4-in-1, with the last conversion being a full-size bed. After researching online, I found that getting a low-profile box spring is preferred for toddlers so they can get in & out of bed. Otherwise the size of a mattress + box spring + bed frame would be too high for her. I tried shopping for a low profile box spring locally at various mattress stores and couldn't find anything cheaper than over $100 (plus they wanted $50 for delivery). So I just ended up finding this product on Amazon along with the mattress. For those of you wondering, I paired it with this product: . Assembly was easy and took about 15-20 minutes. The instructions just consisted of pictures, so you just match the pieces in the picture. One reason I am docking a star is because one of the support bars on one of the pieces welded incorrectly. It actually caused the piece to not match up with the bolt hole. I had to "bend" the piece in order for it to line up with the bolt hole. In addition, some spots of the metal where it wasn't coated (metal spots near the weld were exposed) showed signs of minor rust. With those issues aside, this product makes for a VERY STURDY foundation. Fully assembled, it does not bend at all and is a perfect platform for the mattress. I do like how the product comes with a cover (to make it appear like traditional box springs). I just hope that no one jumps on it when exposed because I distinctly remember jumping on the box springs when I was a kid. Otherwise they'll slip right through. Good product!

First impressions of this Zinus Smart Box Spring/Foundation are great! I purchased the full size, and just put it together by myself in about 30 minutes. It arrived in good condition with no damaged or bent parts, and everything fit together easily as it should have done. Instructions are diagrams, but are clear and easy to follow since all of the parts are labeled with numbers and "UP" to correctly orient them. The included ratcheting Allen wrench was helpful to get all of the bolts tightened. The cover goes on just like a fitted sheet with elastic around the bottom edges and gives the visible sides a nice finished upholstered look. It feels sturdy and fits very well in the frame of my antique bed. I love the low profile. The only down side: it was shipped USPS (rather than UPS or FedEx) and my local post office wouldn't deliver it because it was "oversized" and they labeled it "two person lift". I had to pick it up the day after I had expected delivery. It does come in a long box, but I carried it to my car by myself without a problem.

Very easy to put together! Works as it's supposed to. Full size doesn't translate to 140X200. It's a bit short, but we have it on top of the flat bed slats to keep in place. Should sell in cm.

I will always buy this type of box spring from now on. A bit of pain to put together. But once you got it. It’s simple. Instructions could be better. However. Very sturdy. I don’t see it breaking like wood. And if you have tight spaces it will always fit in your room !
