  • Sturdy and Quiet
Size: Full
Easy to set up, no need for a box spring so now a noise free sleep experience. Room for storage underneath, and bedding hangs down and covers the open area underneath. The white finish is crisp. The legs have rubber feet so the bed doesn't slide across the floor, it must be lifted to move.

  • No squeak bedframe
Size: Full
Very easy to assemble without tools, took about 10 minutes for this 74 year old woman. Once assembled, put on the mattress and tried it out. No squeaky noises from the frame unlike some others we've had. Perfect for my full size memory foam mattress.

  • Sturdy and easy to assemble
Size: Twin XL
My 20 year old daughter needed a bed frame for her apartment. She put it together herself easily and really likes it. Definitely recommend.

  • Easy To Set Up and Comfy
Size: King
This bedframe was easy to set up, looks fine, and was a good price. It doesn’t rock or move and it is pretty comfortable as well. It’s very quiet compared to many traditional bed frames. We bought it for a king mattress that is particularly heavy due to having gel in it and it seems to be holding up very well. I like that the legs are inset for those of us who always stub their toe on their bed leg. ... show more

  • Nice, but not enough brace bars.
Size: Full
I got this for my son's room, and it puts together fast and easy and seems quite sturdy (he's an adult and weighs about 150 pounds). We haven't folded it up, so I have no idea if that is easy or not. The only complaint I have is that there aren't enough braces close enough together to keep tucked sheets from falling through and hanging on the floor. ... show more

  • My long awaited bed
Size: Queen
I purchased this bed after shopping around for a while. I have a similar full size one that I use in my guest room, and I love it. However, it is black and the colors in my master bedroom are light blue walls with white trim, so I wanted a bed frame in white. I also did not want a headboard or footboard, so this works great. I like that it is a lot lighter than a regular bed and I am able to move it by myself. I also like that it folds up so it easy to move around the room or from room to room if needed. (That's also a great asset if you are moving to a new house/apartment). It was easy to assemble and, again, I was able to do it myself. I also appreciate that you don't use a box spring with this type of bed so again, it is less cumbersome and easier to move alone. I am still using my regular mattress until I get a new one, but I plan to get one of the mattresses in a box for ease of moving that too. The best part of this bed frame is the amount of storage space that it provides underneath. That allows you to have fewer things in the open within the room but still have them on hand. My cat especially likes the space and spends most of his time under there now. I plan to get one more bed frame like this for my son because he is upgrading his bed in his new apartment. You can't go wrong with this frame, and I am glad that I found it. ... show more
