## Customer Reviews

### ⭐⭐⭐⭐⭐ Start to finish, a quality product with *excellent* QC
*by E***S on July 14, 2025*

I can't say enough good things about this box spring. First, I had no idea that there *was* such a thing as non-standard box springs, and was pleasantly surprised to find so many options available. I went with this particular company because of the overwhelmingly positive reviews, and am happy to report those aren't just so much smoke being blown.From start to finish, this item was a) easy to put together, b) showcased quality construction, c) had great instructions, and d) included little touches that made me say "Why aren't more people doing this!?" Just as a couple of examples: they included a *ratcheting* hex wrench to make it easier to tighten a couple of the harder to reach screws (and it's a nice one that I plan to use whenever I get the chance). Also, the places where pieces need to match up (e.g. where the header and footer needed to attach to the side rails) had the same number on them. If the numbers match, you know everything is oriented the right way - brilliant! I've made a *LOT* of flat pack furniture in my day, and this was such a welcome "quality of life" move.I tested my bed out last night, and heard no creaking or squeaking (and I tend to toss and turn); if anything, my bed felt more solidly supported and comfortable with this box spring as a foundation. I would 100% purchase from this company again, and would recommend them highly to others.

### ⭐⭐⭐⭐⭐ Perfect for foam beds
*by N***. on February 18, 2019*

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.

### ⭐⭐⭐⭐⭐ Works great with a memory foam mattress
*by P***R on December 13, 2021*

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!
