Safety Warning This product requires a separate bed frame or platform bed for support.

Always follow the manufacturer's instructions for safe use and assembly. Review: that it fit a single bed - it is just what i wanted Review: Perfect solution for box - We got a new bed frame for my young teen son which required a box spring mattress. I was not looking forward to having another giant mattress to drag upstairs. This frame was the perfect solution at a great price. The delivery box wasn't too big (compared to a full-sized mattress), and it was pretty easy to put together in just a few minutes. It seems to be pretty sturdy. I also like that it came with a fabric cover, although, it did have a small tear which won't even be noticeable with the main mattress on top. ## Features - STRONG, DEPENDABLE, AND READY IN NO TIME - As if its ultra-durable steel structure and convenient packaging weren’t impressive enough, our original Smart BoxSpring has been given a quick-assembly upgrade - DURABLY ENGINEERED - Durable steel is used to construct the inside framework of this foundation; twin/twin xl sizes support a maximum weight capacity of 350 lbs, while all other sizes can support up to 700 lbs - EASIER THAN EVER ASSEMBLY - With fewer bolts and tool-free locking brackets for intuitive setup, assembly takes only minutes to complete - THOUGHTFULLY PACKAGED - All parts and instructions are packed into one compact box that ships straight to your door - Worry-free 5 year limited warranty included; box spring only, a bed frame or platform bed is required to support this foundation and is sold separately ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09XM7BP1T | | Brand Name | Zinus | | Colour | Grey | | Compatible With Mattress Size | Queen | | Customer Reviews | 4.1 out of 5 stars 566 Reviews | | Finish Type | Steel | | Form Factor | Box Spring | | Furniture Finish | Alloy Steel | | Global Trade Identification Number | 00841550325355 | | Included Components | Cover, Slat, Steel Frame | | Is Assembly Required? | Yes | | Item Depth | 54 inches | | Item Dimensions | 199.9 x 151.1 x 17.8 centimetres | | Item Dimensions L x W x H | 2.01L x 1.51W x 0.18H metres | | Item Shape | Rectangular | | Item Type Name | Box Spring | | Manufacturer | Zinus | | Manufacturer Part Number | ZU-ABS-7QS | | Material | Steel Fabric | | Material Type | Steel Fabric | | Maximum Weight Recommendation | 317.52 kg | | Model Number | ZU-ABS-7QS | | Other Special Features of the Product | Durable | | Product Care Instructions | Wipe with Dry Cloth | | Product dimensions | 2.01L x 1.51W x 0.18H metres | | Size | Queen | | Special feature | Durable | | Style | 7 inch | | Style Name | 7 inch | | UPC | 841550325355 | ## Product Details - **Material:** Steel Fabric - **Product dimensions:** 2.01L x 1.51W x 0.18H metres - **Size:** Queen - **Special feature:** Durable - **Style:** 7 inch ## Images ![ZINUS 7 Inch Metal Smart Box Spring with Quick Assembly, Mattress Foundation, Strong Metal Frame, Easy Assembly, Queen - Image 1](https://m.media-amazon.com/images/I/61e4dd+fl8L.jpg) ![ZINUS 7 Inch Metal Smart Box Spring with Quick Assembly, Mattress Foundation, Strong Metal Frame, Easy Assembly, Queen - Image 2](https://m.media-amazon.com/images/I/817Eo9cK32L.jpg) ![ZINUS 7 Inch Metal Smart Box Spring with Quick Assembly, Mattress Foundation, Strong Metal Frame, Easy Assembly, Queen - Image 3](https://m.media-amazon.com/images/I/71LXSplDg1L.jpg) ![ZINUS 7 Inch Metal Smart Box Spring with Quick Assembly, Mattress Foundation, Strong Metal Frame, Easy Assembly, Queen - Image 4](https://m.media-amazon.com/images/I/81Z-spx5IhL.jpg) ![ZINUS 7 Inch Metal Smart Box Spring with Quick Assembly, Mattress Foundation, Strong Metal Frame, Easy Assembly, Queen - Image 5](https://m.media-amazon.com/images/I/71xq2TKOTfL.jpg) ## Questions & Answers **Q: Are any tools required to assemble my box spring?** A: Yes, just a few!
