    • Nice frame.
Color: 22 Inch Size: Full
It is very stable and durable. Assembly was easy and despite the instructions saying to have two people to put it together, I was able to put it together all by myself. Once I figured out the parts and just kind of lined them all up where they needed to go, all I had to do was just lock everything into place and then screw it all nice and tightly. This frame has endured my wild sleeping as well as wild love-making and hasn't given out yet or even showed signs. It does sit up rather high though, so consider that when selecting the thickness of your mattress. I have a full size 14 inch gel memory foam mattress installed and it makes everything it up way higher than I would like it to. But I got the 14 inch since my bf does come over sometimes and we do share the bed. I didn't want it potentially sinking with a thinner size. I've the clearance space underneath for storage though, and that's really the main reason I chose this frame over a lower one. I need all the storage space I can get. ... show more

    • Amazing!
Color: 24 Inch Size: Queen
I got this to create vertical storage in my room. I have cats so they like to explore. The amount of space underneath is awesome and I know they’ll have so much fun under it, It looks great! I was able to assemble it alone, although it’s recommended to have a second person. This is probably because of the amount of screws that were needed. The noise level really wasn’t bad at all, I might’ve heard one small creak but that’s it. I think this is priced fair considering the type of material used for the bed. It’s a strong type of metal. I’m very pleased with this and I highly recommend it. ... show more

    • Really stable and not that hard to assemble
Color: 24 Inch Size: Twin

    • 24” inch bed frame.
Color: 24 Inch Size: Queen
I highly recommend this bed frame. I love the high height, because I’m tall also love the extra under bed storage. It was very easy to put together. Labeled very well. If you want a more durable bed frame this will be the perfect one.

    • Sturdy, simple frame
Color: 24 Inch Size: King
This bed frame is VERY high but it's what we wanted. I'm 5'6" and use a small step stool to get into bed because the frame is 24" and the mattress is another 18" or so. Our plan is to raise it even higher to build a dog bed under the frame for a large dog. The frame is heavy duty and should hold up to an 18" foam mattress, two adults and a dog just fine. We will reinforce it so that IF it breaks, it won't hurt the dog(s). It doesn't squeak or wobble. We did buy a mattress board to go over the top of it before putting on our foam mattress. It was fairly easy to put together for two people. It simple but looks just fine. I'd definitely buy this frame again. ... show more

    • Give yourself time to assemble and pay attention to instructions
Color: 18 Inch Size: King
This is great and very strong. This only got 4 stars from me because the mattress doesn't want to completely stay in place on this support. I am assuming that is what the "mattress blockers" are for but only a little bit effective.

    • Great product
Color: 22 Inch Size: King
Extremely sturdy. This fit perfectly within our existing bed frame and allowed us to raise our mattress up several inches. Sturdy well built doesn't make any noise.
