    • Best value and quality I’ve ever bought!
Size: Queen Style: 14" Pattern Name: Bed Frame
I’ve bought other frames before for more money and even had wood slates, that didn’t hold up as good as this one. I did a lot of research this go around, and found this one on many lists as a quiet and durable bed frame-which was a concern for me. Have had it for 4 months now and zero sound or squeak when getting in or out or moving around. I bought the heavy duty even though at 145lbs I could have saved a little and bought the regular. What I was most surprised at first glance was how thin the frame looked out of the box and how lightweight it was. I thought I had made a mistake with this one, but I was proven wrong. It’s incredibly sturdy. The matress does not move around. The frame stays in place but can be moved without a lot of pressure if I need to clean underneath. It was so easy to put together, also. Literally snaps into place and a few screws tightened. Took about 10min or less. I love that there is storage space under my bed now also. A really great quality purchase. ... show more

    • Updated: Full review two years later! (Preliminary Review: Unboxing and set-up)
Size: Full Style: 16" Pattern Name: Bed Frame
I will write a full review of this bed frame after I have used it for a while but wanted to give a preliminary review first. I've had it for about a month before setting it up (waiting to get a new mattress and get rid of my futon), so it's been in the box which was on the large side but was able to tuck it away in my kitchen for a few weeks. I live on the third floor of an apartment building and while the box was a bit bulky and heavy, I was able to get it up to my apartment by myself with no problem. I'm a big girl with a not-so-great back, but it was definitely manageable. Having forgotten anything I read in the reviews about assembly, I was expecting a cumbersome set-up job with a lot of little parts and pieces and metal clanging around as I jostled this frame around my tiny little one-room apartment. I was pleasantly surprised to find that the frame consists of two separate pieces that fold out, and are then joined together by two screws in the middle. THAT IS IT!! Putting it all together took me about 20 minutes. Probably would have been less if I had more room and wasn't having to rearrange other furniture almost every step of the way. I have my new mattress set-up on the frame and expanding now (I got a Tuft and Needle original mattress which is a little longer than the frame, so not sure if that's a frame issue or mattress issue, but hardly noticeable) and was impressed with how easy it was to move the frame during the unboxing of the mattress and how lightweight it is. I am honestly a little apprehensive about the two pieces of the frame staying together with two screws as the butterfly bolts don't screw as tightly as I would like. I anticipate maybe having to find a washer or nut or something else to just make sure the fastener doesn't come off, but that's super easy so I'm not too worried about it. I did really appreciate that the hardware (two long screws and two butterfly bolts) came in a package together so it was easy to set them aside and not have to worry about them flying around. Oh! I also really appreciate that the frame came with two non-slip pads that are often used for carpets. That will hopefully help prevent the mattress from slipping off the frame. The storage capacity underneath this frame is AMAZING! Because there are two braces in the middle of each section, the storage underneath is in two sections divided horizontally but I can fit so much stuff under just one section because of the height which I am loving in my small apartment. The stuff from under my futon is now under ONE section of this frame, leaving me so much more room to store things that have been getting in the way. I will give it a full review after sleeping on it for about a week, but I'm optimistic that I will be highly satisfied! ****UPDATED REVIEW**** Two years later I am back to finally update this review! And two years later I am still 100% satisfied with this bed frame! When I moved last summer (Aug. 2020), taking this apart on moving day was a snap and it took me five minutes to set it up at my new place. I had previously been worried about the two screws joining the sections coming loose but that has been a non-issue in the last two years. I eventually added a bed skirt to help conceal the totes and things I have underneath, but the storage space has been such a game-changer for me, even when I moved to a bigger apartment. The frame is super quiet and holds up with some company in the bed, so no complaints there! ; ) I really cannot recommend this frame enough, it is one of the best Amazon purchases I have made. If you're looking for something sturdy, easy to put together (seriously only like FOUR PIECES in total!), excellent under-bed storage, and durable, GET THIS FRAME! ... show more

    • Great for platforms
Size: Brackets Style: 14" Pattern Name: Board Brackets
I bought these because I replaced my old boxsprings and frames with platform frames. It was very easy to install these on the platforms that I had, the holes are convenient and I haven’t had any issues matching up different headboards to the holes available.. They keep even heavy, headboards, pretty secure without tipping if the headboard actually touches the floor. It can tip a little bit if the headboard floats over the floor and is heavy.. These are a great price, and I will purchase them again ... show more

    • Very sturdy, no squeaks
Size: Full Style: 16" Pattern Name: Bed Frame
This frame is solid and quiet, sits at a nice height, and folds up in two nice pieces that are easy to store and transport. It might sound crazy, but one of our uses for this is tent camping. The two halves, when all folded up, fit perfectly laying flat on the trunk/cargo floor of our Jeep Cherokee and then in the backseats of the car we pack a Full (F) size tri-fold, memory foam mattress that juuuuuust fits and allows the doors to close. We put our 10x14 tent in our Thule cargo box on the roof with a couple bags and we are ready for a weekend out in the woods (sometimes bring a small enclosed trailer with extra gear for longer trips). It sounds corny to be setting up a whole bed frame and full mattress in a tent, but it is 10000 times better than even the best $150 air mattress we've tried and to us its worth the space taken to transport it. I never liked putting gear on the rear seats anyways so they were already usually empty. With the two halves of this bed frame folded and stacked (blanket between them to avoid metallic rattling) they are only a few inches high and leave plenty of room to stack duffel bags on top of those in the cargo area. We sleep as comfortable on this as we do in our own bed at home (maybe a little better honestly). Beyond that use its also a standby extra bed we can easily throw together for guests at our house. Its pretty quick and easy to assemble the frame and flop the tri-fold mattress down on it. With its height there is lots of storage space under it so we are seriously considering getting a second one for our regular bed at home for full-time use. ... show more

    • I love this bedframe
Size: Queen Style: 18" Pattern Name: Bed Frame
This is my third purchase! I bought a King for me, a King for my BF (because he has a Doodle that likes to sleep under the bed) and a queen for my guest room. I will be buying a full in the near future also for my guestroom. It is sturdy, never creaks, moves, etc. great support for my mattress. I bought the 18" high frame because it has great storage. I recommended it to my sister who has a small manufactured home on the River and needs storages space. Very easy to put together too! I can easily clean under the bed and retrieve items the Doodle carried down below. ... show more
