This is definitely worth the $$ Assembly took approximately 15 minutes.. Box spring cover is nicely made... no noise and very sturdy. Very pleases with my purchase. No regrets.

Just want to start out by saying the slats are super sturdy and fluctuate between 2.5 and 2.75 inches (most foam bed manufacturers require a maximum of 3" between slats for warranty reasons). Okay, now that THAT’S out of the way.This Box spring/Box Frame is AMAZING. I never leave 5 star reviews except for items I think go above and beyond and this one sure does.The design and thought that went into this thing are superb. Extremely easy assembly, extremely sturdy yet super light and super rigid. It even comes with an amazing little allen wrench ratchet tool (pictured). The sides have velcro on them which attaches to Velcro strips which are stapled to the slats, and the slats themselves come in two separate sections. the design is perfect in that you simply grab a section of flats and "roll" it out and stick it to the velcro on the frame which holds it in place.The instructions were clear as far as putting the pieces together and really the ONLY thing I would say that could use improvement is the cover itself. Its designed in a way that it zips on three sides and you "wrap" it around the frame and zip it up, the issue is that when you do this you have to have two people: one to hold the frame up and the other to pull it through along the bottom. Once you do get the bottom section of the cover under the frame itself, everything gets easy and you simply zip it on up.I know this is "simply" a box spring, and maybe I am just so used to the old crappy styles. But this one is WELL worth the money. Strong, Stable, easy to assemble, perfect for foam beds, comes in a relatively small box. You cant go wrong with this one, and I will be buying again if I am ever in need of a box spring in the future.

We transitioned from a box spring to this item. Our box springs was quite old and this item has been hands-down a huge improvement. I'm quite interested in whether the longevity over a decade or more exists but I would be willing to buy another one every 5-10 years if we had to because it is just such a solid product right now and works really well and was pretty fun to put together!Thanks to other reviewer's comments, I was anticipating the confusion on which way to put the cover on. Here's my attempt at clarifying the issue: The zipper surrounds the head AND foot and 1 "side" of the frame. It is understandable that people would assume the zipper should surround BOTH sides and either the head OR the foot but that just ain't so. Line it up properly along one side for success.The directions were super easy to follow; all the pieces' connections were numbered; all the screws were packaged nicely; the Velcro and staples to properly/evenly space the slats were an excellent idea; there was even a really handy tool included to install the screws quickly and easily!My #1 reason for replacing my box springs was to eliminate the constant squeaking sounds. Mission accomplished! Getting into bed or moving around no longer has a vast array of squeaking noises. It's funny the things you can get used to; I still keep expecting my bed frame to make its noises every time I sit down but it NEVER DOES now! There is a foam/rubber piece running down the entire length of the middle part of the frame adding additional sound dampening (I imagine). The sides and their Velcro attachments never wiggle nor make Velcro ripping sounds.This is working out great for supporting our considerably heavy memory foam mattress; I was a little bit concerned that the slats would be too far apart or the wood too weak for the heft and weight of the mattress + people but no problems so far.If it were easy to get the cover on and off, I would be doing so just to see how much movement getting in/out of bed and/or bouncing on it causes the wood slats to "give". But since the cover is on, I have no idea. Maybe in 2 years we'll break through one or more slats not realizing the stresses we were constantly placing upon them but I currently feel like that is unlikely. No creaking or other stress-related sounds so far!The cover looks nice if you aren't inclined to cover the cover. Hope you are able to enjoy it, too!* 2024-02-29 Update! No changes whatsoever. This product ROCKS!

This was shipped in a timely manner. Once I opened it, I knew it was going to be an easy job to put together. It only took me 15 minutes to put it together. The cover to go over It was really easy. I read in some reviews. Some people had a hard time getting it, but it only took me to do it. If I needed to order another one I would not hesitate. It is sturdy and it fit my full-size bed frame with no . I highly recommend this.

This thing is super cool! I mean lets be honest, what does a box spring do... occupy space, add some height and ventilation. So by it's nature it is bulky but really not made of much. I did not expect it made sense to have an item like this shipped. Until I found this.Setup was super easy and did not take long at all. Also it came with a pretty slick tool, which was a nice surprise and very smart to include. I also think this is a lot nicer than the box springs I have seen in the past. We have had this in use for over 6 months now with no issues encountered. It has held up to my nightly performances and has not complained at all. Likewise I have no complaints. STOP SHIPPING BIG BULKY BOX SPRINGS AROUND THE GLOBE, as this has to be way smaller of a carbon footprint.

Comes in a long box, about 7 ft, we opened it in the garage, and carried all the parts up to the second floor which has narrow stairs and a landing half way. Took only about 10 minutes to put it together, is is very well designed, and quite solid for our foam mattress to sit on. Before our mattress sagged in the middle, but with this box spring, not at all. Instructions are very clear and easy to follow. The whole structure is very light. The cloth cover was easy to put over it. Would certainly order one of these again. Very, very pleased.

Although I wouldn't depict this item as a box "spring", since there are no springs, it was the perfect low profile frame for our new very deep mattress. It was easy to assemble and is very sturdy and I no longer need to take a run and jump to get onto the bed. This low profile frame allows our mattress to sit at a much more comfortable height.

This is the second Zinus bed I get and I will definitely be a returning customer if I ever need to change my bedframe again. It arrived in perfect shape, not a scratch. SUPER easy to assemble, and no flaw whatsoever in the build of the frame. Just as advertised by the manufacturer, this bed makes ZERO squeaking noise. I was happy with my previous 14" Zinus bedframe, but I needed to change it because I got a new mattress that happened to be 15" high, which required a lower bedframe for me to be able to get into my bed without feeling like I'm "climbing " into it!! The bonus with this frame is that it can be used as a spring box (with the fabric cover) or as a bedframe, in which case it has a modern and neat look. The only downside to using it as a bedframe is that it doesn't have anti-slip pads on the bottom so if you worry about scratching your floor, you should think about adding a carpet underneath or come up with another idea. Oh and did I meantion that this bed has a sturdy feel to it and the wooden flat slats are perfect for heavy mattresses like mine. The distance between the slats is small (2.6 inches) and the slats being flat, they don't leave marks at the bottom of my mattress. I got it on sale for 200$, so bonus!!!
