Highly recommended this frame
These frames are awesome. They fold up so nice and compact and the set up is super quick and easy. They are very sturdy and give a lot of support to the mattress. We had two I Comfort Memory Foam Mattresses that are still in good enough condition for company but we don’t have an extra room to keep them set up all the time. So, we store them in our cargo trailer and was just going to lay them on the floor for company. Well since most of our company would be older and have issues with being on something on the floor I thought well we could get like a roll around frame but they all come with a mattress and are 2-3 times more expensive. Then I came across these folding frames. These things are awesome. Our mattresses fit perfectly and there is no movement or sinking it keeps the mattress firmly in place. My husband is 6’3” and 260 lbs and it held him solid. When folded up I don’t think it’s more than 4 in thick and like 56 in wide. You can easily store away in a closet. I can’t say enough good things about these frames. I bought 2 and they both came packaged well and in great condition. Would probably be even good to take camping and maybe throw an air mattress or just some thick foam on.

Best value and quality I’ve ever bought!
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.

So far not squeaky and hasn't collapsed
The whole frame is light weight and easily folds up. It comes with two screws/butterfly bolts to link the two together (I got the full size). My only complaint about this product are that the screws are neither Phillips, flathead, nor star heads. Possibly allen wrenches. Meaning I know not what tool can be used to tighten it. With the butterfly bolts I can see this expecting to be hand tightened (which I did). I don't anticipate any cardio on this bed but I imagine the shifting from that could loosen these, so consider getting a second set of hardware for peace of mind.One thing to note is that the pair of top feet, middle feet, and feet of the bottom of the bed are supported by a cross beam. Normally this extra support and stability in something holding you up for a third of the day would be a good thing. However this feature means that you can only slide boxes in from the side, and only from the front half or bottom half of the bed. Meaning that you cannot slide boxes in from the foot of the bed, but the side by the foot. Be mindful of this when you orient your bed. Mine is the corner of the room and the majority of the access is only by the foot of the bed and the bottom half. I fortunately have a gap by the top of the bed I can squeeze stuff through and under the bed. But the major selling point is that this is high enough for storage, however you cannot access the entire space from any other side of the bed to store boxes. Possibly the under bed, slimmer boxes could slide under, however my storage is based on larger bins.Update: After flipping my mattress routinely, the small cross bar ends did snag on the mattress protector. surprisingly when I took the box it came in, apart (I only cut the tape and prised apart the glued side), the cardboard lay out almost even with the surface area of the bed frame, meaning that with some zip ties, you can use the box between the bed frame and mattress to protect the mattress from the cross bar ripping it.

Sturdy and easy to set up.
This is very sturdy. I have a10” mattress on top of it. There was no assembly. I use it in my camper van so I needed something that was easy to put in sand take out when I wasn’t camping. The legs fold in to make it easy to carry and store.The only minor issue I had was that my mattress slid on it because there are no sides. I solved this by purchasing things that slide on to the frame and are raised up to hold the mattress in place. There were six in the set.I highly recommend this bed frame.
