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.

I was looking for a sturdy, easy to put together bed - this is both! The overhang is great, so no one bangs their toes on the legs of the bed and there's enough room underneath for storage. Highly recommend the Twin Xl.

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!

My review is for the FULL sized, DELUXE option. I read through many reviews across multiple brands of foundation/frames. I looked for information pertaining to the durability, sturdiness, longevity of each with particular interest toward reviews that mentioned heavy individuals that sleep with big dogs. Specific, I know. Seems that ALL of the foundation frames have a rating for well over a thousand pounds. Feeling better about my 300lbs, I figured I would be fine with any one of them, even when including the weight of my mattress and that of my two big labs. YET, so many people mention creaking beds, frame pieces that bend, etc and they are normal to light weighted people. So I jumped from product to product trying to find something I thought would be a good purchase. If not, my plan was to use a typical frame and box spring. When I came across THIS product, I saw that they recommended their "Deluxe" option for heavier individuals. "Reinforced stability with t-shape leg construction and locking system / Best fit for larger than average weight people" Ok, no matter how I spin it, that is me. I still hemmed and hawed, especially when I saw other products at least resembling it-- but that didn't mean it actually was the same product. I went ahead at put it in my cart while I took another peek at the perks and details. Clearly I went ahead with it, paid the extra for the Deluxe. Maybe the regular would have been fine. Maybe the Deluxe could have been a waste. My experience so far has been stellar, so I am very pleased to have plunked down the extra cash to buy the DELUXE option. --Design- legs set back so as not to smash your toes. I wouldn't have thought about it except some reviewers mentioned it (thank you reviewers)! The recessed legs are a safety and comfort feature. If you have stubbed your toes on a bed foot, know that this thoughtful feature will be greatly appreciated by all who walk near the bed. (again, Deluxe frame) --Ease of "assembly". I put that in quotes because it isn't much of an assembly needed. The frame comes in two narrow cot sized frames. These are set up super easy by just unfolding and straightening out the legs. The legs just need to be attended to by hooking a stabilizing arm and tightening a wing nut. Do this for all, then flip upright and put into position. Even easier is connecting the two frames to make one full sized frame. Bold and nut are provided. All done! --If you want more detail, look further down the product page to "Technical Specification". You will find a highlighted link that will open a User Manual. From there you will quickly see what needs to be done. It takes barely any time. I even had cats and dogs trying to "help" me in a small space and it added no time. --Sturdiness: My full sized bed is set up on a carpeted floor. I imagine that makes a difference, but I do not know. The surface of the frame is smooth- no pointy, sharp edges, so there was NO issue with it catching the material of my mattress. I don't recall if that was ever an issue here, but I recall seeing it across several reviews perhaps from other brands. --I have been using my bed nightly for a month. My two labs and sometimes a few cats join me- no creaking or unwanted movement. My husband and I have two full sized beds set up side by side to accommodate our large furry family, and to allow for better rest, yet he occasionally also um.. "joins" me, (and I know you know what I mean). No issues there either. Bed is still standing firmly in place! --I totally love the space under the bed. So do my cats, and at first, so did my dogs. It was this mysterious magical land to be explored. I don't really use it for storage at this time, but I like the option. All my pics include my curious menagerie. Orange cat, Charlie demonstrates difference in height (floor clearance) from typical frame to this frame. Huge difference! While my husband also has a full sized bed, his is currently a typical low frame, with a box spring, and topped with a mattress. Mine is this tall frame and a hybrid mattress (that comes in a box), and all together, side by side they are the same height. I hope to replace his with exact same set up as mine, eventually. So far, I am super pleased with this frame. I keep up with my reviews and will definitely come back if I have any further thoughts, revelations, problems, or even to just say it is still going well.

This frame is super simple to put together and is very sturdy. I did four stars only because the mattress does slide a little bit on it and I have to adjust it every night to get it back into place. My mattress is not really heavy but it didn’t move on my other frame, which was a completely different type. I’d say it moves about an inch or two. Not a big deal to adjust.
