Size: King Color: Grey Pattern Name: Mattress Foundation
I held off on getting a platform for our king bed because I didn't think it would work with the wooden sleigh bed frame/headboard/footboard we had. Having purchased a couple Zinus frames for other beds (twins), I decided to look at them more closely, and I realized the construction of the frame probably would not interfere with the wooden sleigh frame. I ordered the frame and assembled as soon as it arrived. Loved the packaging and the instructions - super simple and no tools required other than what's provided (they even provide a small mallet!) The way the supports of the bed frame are designed is a true differentiator from anything else out there. Instead of being flush with the edges (would not have been compatible for my sleigh frame), they sit about an inch inside the edges - thus allowing the frame to sit neatly inside my sleigh bed frame. And the frame is completely silent. After years of squeaks and creaks, I now have a bed that is silent and completely sturdy. Couldn't be happier with this purchase! ... show more

    • Headline: Drunk 5'4" Single Woman Assembles King Bed Alone And Nothing Broke
Size: King Color: Grey Pattern Name: Mattress Foundation
I ordered this because it looked and claimed to be easy to assemble. I live alone on the third floor of a big apartment complex, the kind where humans live in their little cubby holes in a row of cubbies. I wanted to eliminate the hauling I'd have to do as much as possible, and was delighted to find some poor UPS guy had delivered the 7 ft long box directly to my door. I was doubly-delighted because I was already a bottle of wine in that evening and I'm one of those cursed with the propensity to break things, sober or not. There are pictures of 2 men lifting all over the box, clearly indicating what was expected to do the job, so of course I grabbed the box and wrestled it into my apartment all by mahself, because #feminism or whatever. I should preface the remainder of this review by explaining that I may be all of 5'4" on a good day, but I'm also a competitive bodybuilder, so I can lift things and stuff, but once the bed was indoors, things got easier. So if you're all of 5'4" and not a bodybuilder, that first part may be hard, but I believe in you. The instructions were only two pages, but I wasn't upset. I mean, lately I've seen the furniture directions where the paper is one page with 100 different pieces depicted, with all the arrows pointing to them all going together, so the instructions are literally just, "Take all the parts and put them together, then done." Those make me want to hurt someone. But these instructions made all the sense. You take the big pieces, hook them into each other, and then you already have the base done, boom. They even supply a super cute little rubber mallet to make the process easier. Of course, I didn't see that until I had man-handled all the pieces into place and was sweating out all the wine. Then you drop the slats into place, easy peasy. But then, this slip cover.... Look, my one complaint is that it came with a tag that explained which way was forward, top, etc. on the slip cover, but the thing had fallen off and was sitting sadly in my hand while I stared blankly at the slip cover, not knowing which was was up, down, or sideways. So I had another sip (swig, chug...) of wine and began wrestling that damn thing on. Now I know from experience and can warn you that if the slipcover fitting feels impossible and makes you curse the fact that society thinks that mattresses on floors is unacceptable for functioning adults, you are probably putting it on wrong. I wrestled with it in 3 different directions until the last time, it finally seemed to fit right into place, and I realized I had it right finally. Hint: The zipper zips on top. Yeah, didn't realize that the first 2 times. The legs go on way easier than expected, right through pre-cut holes in the slip cover. And then BAM. I was suddenly an adult again and no longer sleeping on the floor. So if you're wondering if this will be as easy as it claims and work for you, the answer is probably yes. I might recommend the wine to go with the experience. Particularly, a good cabernet will help get the job done. Men not required. ... show more

    • GOOD DESIGN but not great
Size: California King Color: Grey Pattern Name: Mattress Foundation
The design and simplicity of the design is amazing. You could build it yourself but with two people it goes a lot faster and is more fun. It is easy to see why the ZINUS won the GOOD DESIGN Award with this design. However it is not all roses for the Justina Metal Mattress Foundation; let's get into it. After a few weeks the frame starts to make a creaky sound you get in or out of the bed. Only happens when weight is taken off the frame and not with any other motions. So it is not horrible however it will wake up anyone already sleeping in the bed should you get in or out of bed. This is all that is keeping it from five stars. ... show more

    • Stop Shopping Around and Buy This!
Size: Queen Color: Grey Pattern Name: Mattress Foundation
I didn’t know about Zinus until I started shopping for a bed frame, but I am so glad I found it! This foundation is everything I’ve wanted. I purchased a box spring cover to mask the gray cover that comes with the foundation and it fits my room decor perfectly. The box as a whole is kind of heavy, but the individual pieces aren’t. I was able to get the box in the house, open it, and move the pieces to the assembly space fairly easily. Assembly was quick and easy as well - one thing I will say is some of the posts aren’t completely level, but I was able to adjust the screws so it wasn’t rocky. Even with that information, I’d still give this item 5 stars. I also need to furnish a guest room, and Zinus is the only brand I’ll be purchasing from! ... show more
