Review: Es un buen producto, lo recomiendo - 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 Review: Much better than expected - Putting the box spring together proved to be easier than I imagined. I have a bad back so bending was a problem so I took rest breaks. The instructions are basic and easy to follow. I suggest if you have a small ratchet set, use it for the nuts. The tool provided is OK but a ratchet set is much better and faster. The Allen ratchet provided for the screws was great and will be used in the future for other projects.Measure the cover before installing is also a good idea. It will save time and not rip the fabric. Assembly can be done by one person but the cover really needs two. The finished product appears to be solid and the King size mattress fitted perfectly on top of it. So far I'm happy with the purchase. ## Features - THE LAST BOX SPRING YOU’LL EVER NEED - Crafted from solid steel for lasting strength, and compactly packaged in a single box with all parts and instructions included - DURABLY ENGINEERED - Durable steel is used to construct the inside framework of this foundation; Twin size supports a maximum weight capacity of 350 lbs, while all other sizes can support up to 700 lbs - HIGH PROFILE DESIGN - A 9-inch height is perfect for shorter mattresses or for those who enjoy their bed higher off the floor - VERSATILE FIT - Compatible with all Zinus mattresses and bed frames; please confirm dimensions before using with non-Zinus products - WARRANTY INCLUDED - Included a 5-year limited warranty for the box spring only; a bed frame is required to support this foundation and is sold separately ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00NPVCOSC | | Best Sellers Rank | #283,155 in Home ( See Top 100 in Home ) #779 in Bed Frames | | Brand Name | Zinus | | Color | Black | | Colour | Black | | Compatible With Mattress Size | Full | | Customer Reviews | 4.5 out of 5 stars 74,589 Reviews | | Form Factor | Rectangular Box Spring | | Furniture Finish | Black | | Global Trade Identification Number | 00841550068627 | | Included Components | Foundation, Cover | | Is Extendable | No | | Item Depth | 9 inches | | Item Dimensions | 188 x 134.6 x 22.9 centimeters | | Item Dimensions L x W x H | 188L x 134.6W x 22.9H centimeters | | Item Type Name | Box Spring | | Item Weight | 36.38 Pounds | | Manufacturer | Zinus - DROPSHIP | | Manufacturer Part Number | OLB-ABS-9F | | Material | Alloy Steel | | Material Type | Alloy Steel | | Model Number | OLB-ABS-9F | | Number of Items | 1 | | Number of Packs | 1 | | Other Special Features of the Product | HIGH PROFILE DESIGN, Versatile Fit | | Product Care Instructions | Wipe with Damp Cloth | | Product dimensions | 188L x 134.6W x 22.9H centimeters | | Required Assembly | Yes | | Shape | Rectangular | | Size | Full | | Special features | HIGH PROFILE DESIGN, Versatile Fit | | Style | Box Spring (Original) | | Style Name | Box Spring (Original) | | Target Audience | unisex-adult | | UPC | 841550068627 | ## Product Details - **Material:** Alloy Steel - **Product dimensions:** 188L x 134.6W x 22.9H centimeters - **Size:** Full - **Special features:** HIGH PROFILE DESIGN, Versatile Fit - **Style:** Box Spring (Original) ## Images ![ZINUS 9 Inch Metal Smart Box Spring, Mattress Foundation, Strong Metal Frame, Easy Assembly, Full - Image 1](https://m.media-amazon.com/images/I/81efHkrn1OL.jpg) ![ZINUS 9 Inch Metal Smart Box Spring, Mattress Foundation, Strong Metal Frame, Easy Assembly, Full - Image 2](https://m.media-amazon.com/images/I/81OYF4iuqeL.jpg) ![ZINUS 9 Inch Metal Smart Box Spring, Mattress Foundation, Strong Metal Frame, Easy Assembly, Full - Image 3](https://m.media-amazon.com/images/I/61epyXuOcBL.jpg) ![ZINUS 9 Inch Metal Smart Box Spring, Mattress Foundation, Strong Metal Frame, Easy Assembly, Full - Image 4](https://m.media-amazon.com/images/I/81jdaFW2hiL.jpg) ![ZINUS 9 Inch Metal Smart Box Spring, Mattress Foundation, Strong Metal Frame, Easy Assembly, Full - Image 5](https://m.media-amazon.com/images/I/81KXVcalXBL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Are any tools required to assemble my box spring?** A: This box spring is shipped with everything you need to assemble it - all parts, tools and instructions can be found efficiently packed in the shipping box. **Q: Does this box spring require a bed frame?** A: A basic metal bed frame or platform bed is required to support this box spring.

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. ## Frequently Bought Together - ZINUS 9 Inch Metal Smart Box Spring, Mattress Foundation, Strong Metal Frame, Easy Assembly, Twin - FDW 8 inch Twin Mattress Gel Memory Foam Mattress for Cool Sleep & Pressure Relief, Medium Firm Mattresses CertiPUR-US Certified/Bed-in-a-Box/Pressure Relieving (8 in, Twin) - Utopia Bedding Waterproof Mattress Protector Twin Size, Premium Terry Mattress Cover 200 GSM, Breathable, Fitted Style with Stretchable Pockets (White) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/347564066-zinus-9-inch-metal-smart-box-spring-mattress-foundation-strong](https://www.desertcart.gr/products/347564066-zinus-9-inch-metal-smart-box-spring-mattress-foundation-strong) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-30*
