Customer reviews
Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
Learn more how customers reviews work on AmazonCustomers say
Customers find the bed frame easy to assemble, taking less than 10 minutes, and appreciate its sturdy construction as a solid foundation for memory foam mattresses. Moreover, the frame works well with IKEA beds, offers good value for money, and is lightweight and easy to maneuver, with zero squeaks or noises. However, the fit receives mixed feedback - while some say it fits perfectly, others mention it's not big enough.

- Reviewed in the United States on May 29, 2025Style: New/upgraded with quick assemblySize: FullVerified PurchaseThis is my first Amazon review, and I want to share how impressed I was with this foundation. I had bought a different brand metal foundation which was sadly slightly too large for my full bed. I ordered this hoping it would be lower profile and it was a perfect fit. In comparing the two foundations, I also noted that this was far easier to assemble. Will be easy to take apart for moving. Feels sturdy, expect it will last a long time. Very pleased with the experience especially compared to similar products, and for a great price.
- Reviewed in the United States on June 10, 2025Style: New/upgraded with quick assemblySize: QueenVerified PurchaseFantastic box spring. The item is easy to assemble and comes together in well less than an hour. Clever pop in pieces and few bolts make for a sturdy bed frame. A hex wrench and a little socket hex wrench are included, though I couldn’t get the knack of using the socket hex wrench. The regular hex wrench was more than adequate .The cover is well made and fits well. Pleased with this purchase
- Reviewed in the United States on March 24, 2025Style: New/upgraded with quick assemblySize: QueenVerified PurchaseOrdered 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.
- Reviewed in the United States on January 7, 2017Style: OriginalSize: FullVerified PurchaseBefore 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: Home Life Harmony Sleep 8" Pocket Spring Luxury Mattress, Full, White.
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!
- Reviewed in the United States on May 17, 2024Style: OriginalSize: FullVerified PurchaseI 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.
- Reviewed in the United States on April 8, 2025Style: New/upgraded with quick assemblySize: QueenVerified PurchaseI assembled it on my own and it was so easy!! Very happy with the whole process.
- Reviewed in the United States on January 25, 2025Style: New/upgraded with quick assemblySize: TwinVerified PurchaseThe 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!!
