Very sturdy and quiet. Came together very easily. I love the height as I like to use the underside of the bed for a lot of storage. We have definitely put the structural support of this to the test and it absolutely passes.

Very sturdy, not squeaky, and pretty easy to put together. I would reccomend for anyone looking for a bed bed frame. I’m a larger guy and this is great. The space underneath is great for extra storage and I ordered a bed skirt to go along the bottom to hide it and looks great. The 22 inch height may be too tall for some people. I’m 6’2” and it’s almost too tall for me. My girlfriend is 5’5” and she has to jump up sometimes, but this isn’t a complaint. It doesn’t bother us.

This is a good bed frame. It is sturdy, fairly easy to put together. Much easier if you have two people to help with assembly and goes pretty quick. There is ample room under the frame to store totes under the bed which is always useful. I like it. I purchased the full size and this works for me.

This bed frame was relatively easy to set up, and makes no noise at all when using the bed. Directions were accurate. This frame is 18 inches high, which raised the bed quite a bit, but we can fit a lot of things under it. Together with our 14 inch new mattress it is high, but we purchased stepstools to get onto the bed. I am 5 foot 5 for info, and the stepstool made it easy. The stools easily slide under the bed for storage. Love the look! Feel like a princess on this bed! Would purchase this frame again in a heartbeat!

Not too difficult to put together, although the instructions could have been a little bit clearer. The real problem is how loud it gets. It takes about a week to start making noise, but then every tiny movement gets it squeaking. And if you decide to get even the slightest bit physical, every neighbor within a 10 mile radius is going to know about it.

We are pleased so far. It took a little bit to put together, but no problems. We appreciate the extra space it provides under the bed for extra storage. An additional bonus we didn't expect was that by being able to dispose of our box springs actually made our mattress even more comfortable, and the increased height made making the bed so much easier on our old backs. We should have done this years ago. It is very sturdy and a great value.

Ordered this particular bed frame for my son, who goes through bed frames like crazy; he's almost 6 ft tall 220 lb and this one seems to work. He has memory foam mattress and the feeling is just wonderful with this bed frame. Came when it was supposed to and my husband put it together in about 45 minutes ; not that difficult. I find it very reliable and durable and the bed feels so different with it.
