    • 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

    • Very sturdy!
Color: 18 Inch Size: Queen
Excellent purchase! Fairly easy to put together. My previous headboard worked perfectly. I misjudged the height of the frame considering how tall my mattress is, but it works well with a step stool. This bed frame is sturdy! Definitely recommend!

Went together easily, one person only, all parts fit well. Only complaint is the middle side frame support is easily kicked with bare feet in middle of night, ouch. Quality of frame is perfect, very sturdy

If you want to be a friend that's 36 high easy to put together,this is the one. Very easy to put together. Once you start putting this thing together you'll see when I'm talking about far as the strength and how it's made. No worries about handling the mattresses that you will be using. Definitely a great Buy ... show more

    • Easy assembly & very tall frame
Color: 24 Inch Size: Queen
Easy to put together was a bit weird trying to follow the instructions until we figured out the pieces were already packed together in the order they should go rather than all the same letters packed in the same bundle there was a bundle of tools and equipment for each step. Would buy again if needed a little wobbly even after everything is tightened but works great and does not wobble after the mattress is on it ... show more
