Zinus7 Inch Metal Smart Box Spring, Mattress Foundation, Strong Metal Frame, Easy Assembly, California King

I recently purchased the ZINUS 7 Inch Metal Smart king size Box Spring, and I couldn't be happier with my decision. The assembly process was a breeze, thanks to the quick and straightforward instructions provided. It took me no time at all to have a sturdy and reliable foundation for my mattress. The metal construction gives this box spring a robust feel, ensuring durability and long-lasting support. The 7-inch height is perfect for my mattress, providing just the right amount of elevation without feeling too high. I've noticed a significant improvement in the overall comfort of my bed since switching to this ZINUS box spring.If you're looking for a hassle-free assembly, solid construction, and a budget-friendly option, the ZINUS 7 Inch Metal Smart Box Spring is an excellent choice. I highly recommend it for anyone in need of a reliable foundation for their mattress.

Great frame. It was very easy to assemble, everything clicks into place so there is no need for tools and it took me under 10 min to put together. The box spring is slightly bigger than old one so it was a tighter fit for the bedframe than the old box spring. I do like that the cover on the box spring is removable, this way I can actually wash it several times a year. Overall I'm very pleased with the ease of install and will keep this one in mind when it comes time to replace my other daughter's bed set

Easy assembly, seems sturdy so far, and I love the fabric cover.

To be sure, this is a rock solid, quality product that will last for years and years. Getting it assembled, however, is a chore. I've read the other reviews where someone says something like..."It's so Easy! It only took me 30 minutes." My experience is different. Clearly, the folks at Zinus really tried to make it easy, but they failed. Let me take you through it...1) The directions. As you can see in the photo, for step one, you are to assemble 2 components together. In the bottom left, there is a diagram of what it is supposed to look like when it's fully assembled with 2 red check marks to indicate the 2 components you're supposed to be working on. Well, that's nice, but all of the components in the diagram are the same black color and they are going every which way so it's REALLY tough to figure out the orientation of the 2 components you're working on in this step and all the rest. It would be AWESOME if Zinus grayed out all the components you aren't supposed to be working on and the only 2 you're supposed to be working on were black. That way, you can tell the orientation of your work for this step.2) The hardware kit. As you can see of the other photo, I have a copy of the directions on top and the hardware kit on the bottom. The directions indicate I am supposed to have 10 nuts labeled "G" (I've highlighted it in pink). When you look at the hardware kit, nothing is labeled "G". However, there are 10 nuts labeled "H" (also highlighted in pink). Well, G and H are next to each other in the alphabet - I don't know how Zinus missed this.3) More on the hardware kit. They provide this very nice little ratchet device to assemble it. They also provide a stamped-out-of-a-metal-sheet little wrench which isn't worth anything at all. If Zinus goes to the trouble of providing the nice ratchet device, please provide a worthwhile wrench.4) Final comment on the hardware kit. It's nice to have everything labeled and to even have some spare parts labeled as "spare parts." A nice touch. Regrettably, you need to take out multiple components at the same time and when you punch them out of the back of the blister pack, now you have a whole bunch of nuts and bolts scattered all over the place. It would be awesome if Zinus provided the hardware in little individual, labeled bags.5) The stickers - Each components that you put together is labeled with a yellow "up" sticker and it's really helpful. Kudos for that. Each component is also labeled with a dark green sticker with a number on it. The numbering is critical and very helpful. However, it's a dark green sticker on a black surface and, amazingly, it's hard to find the sticker. I don't know why they don't make it dayglow orange - no one is ever going to see it after it's assembled, and it would make it so much easier to see during assembly.6) Finally, the cards. Zinus includes several "thank you" and "Hello!" cards that you can send to friends and family. Presumably so you can tell everyone about the great Zinus product you just bought. Anytime I have purchased a thank you note card, it always comes with an envelope. Zinus missed this - not an envelope anywhere. What am I supposed to do with these now? I tossed them. If Zinus doesn't want to incur the extra cost of a few envelopes, then a post card would work. I thought this a bit weird though - do people still send letters and notes in the mail?All in all, if you can slog through the assembly, this is a worthwhile product and offers a good value.

Easy to build lasted a while still use it

Quick delivery, easy set up, only took about 5-10 minutes and that’s because I was distracted.

Very easy to put together and super sturdy. Way better than my old wooden one. Great for the new bed. Thank you!

Worst directions in the history of bad installation directions. They should label these pieces to let you know what is what, and a little clear instruction this thing would be fine.Also the cover is really hard to get on and stay on once you are finished getting it together.Saw a video where some people said 5-15 minutes to put this together. I will take that bet. If anyone does it in 5 minutes they have put together a hundred of these things. and have every piece laying out already.

Works as expected, securely holds my mattress in place on the bed frame. Solid construction, the perfect height for my mattress and head-board and easy to assemble. Initial assembly might seem daunting, but just start bolting things together and you'll be done in no time! The cover that it comes with seems durable and I like having the option of removing it and washing it should the need arise. The unit is a bit on the pricey side, but you'll be hard pressed to break the slats on this versus a regular wooden box-spring. And that durability, though more expensive, comes at a reasonable price. I feel I have received good value for my money and a solid product that will serve me well for years to come.

This box spring was easy to put together with the help of someone else! You really just match up the numbers and then screw in the screws and bolts. You just got to know what you're doing. I've been sleeping on this box spring for a whole month now and it's been perfectly fine. No squeaks, no extra movement, and no issues so far! For me and my boyfriend the max weight being on this box spring is around 570 lbs and it's holding up. Read the fine print before ordering as I thought this also came with a frame, it does not. That was my fault. So currently the box spring is just on the floor with my mattress on top of it and there hasn't been any issues as of yet!

As with all Zinus products I've tried, assembly was easy, included ratchet drive was a blessing, fasteners are top quality. However, if you're buying this to fit on top of a metal frame where your primary contact is the perimeter, it will just slip and slide all over unless you McGyver a way to secure it. It was an unfortunate surprise for me, but I drilled out holes at the head and foot and secured the unit with nuts and bolts, then put on the cover. Just think it through.

Was easy to put together and is very supportive.

I cannot rave enough about this product. I was SO doubtful that a "box spring" in such a small box could possibly be sturdy. Every box spring I've ever owned was heavy, and was unwieldly enough that I had to borrow a truck to move one. I tried this one because I urgently needed to get one quick-shipped to my son, who was away at university. It's perfect in every way.Solid & easy to assemble. In the attached pic, I've paired it with a SWBVS memory foam mattress and one of ZINUS' frames. The result is perfect. I will never buy an old-school box frame, again!
