    • Wonderful beds, sometimes misunderstood
Color: Black Size: Queen Style: Basic Assembly
The reviews of these Rumi metal beds are a bit strange, as if different people are reviewing different beds, though it's the same bed. I think there are two problems. 1. The photos look like two small beds that get bolted together, but that's another bed. The Rumi ones just look like that but the two things that look like two beds are just one construction. 2. The parts fit so tightly that it sometimes looks as if the parts don't go with the bed that you received. I'm 81, and I couldn't have put my bed together without the help of a rubber headed hammer that let me hammer the slats in and force some of the screw holes to align. With a hammer helping me to force things into where they should go, I found it pretty easy to make my beds, especially the 2nd one. When things were aligned, the screws started in smoothly and easily by hand and they went in smoothly with the ratchet. The free ratchet is a wonderful tool, but it was important to remove it by jiggling it back-and-forth in the same position, but not turning or twisting it at all, because then you could strip something. It was important to keep aware of what was going on. I think these are great beds, without the formaldehyde off gassing from all new wood, glued or not. And the lower ones are sturdy and quiet; I don't know about the higher ones. I have about a 1" topper on the bottom to keep my no-springs mattresses from dipping between the slats, from sliding across the metal, and to hold my sheets in place. I let it off-gass for a few days before sleeping near it. I like the platform effect for a firm-mattress feel. The cost also is great. ... show more

    • Good sturdy no noise bed
Color: Black Size: Full Style: Basic Assembly
Nice bed. No noise no matter what. I originally thought I was buying a higher up bed but got this one but it still functions well. Very durable and sturdy good amount of underneath storage I just prefer a little higher up than this one. Only complaint is that the mattress constantly slides and moves so I wish there was a little angle so the mattress would stay in place. Other than that. Easy to put together bed especially if you need a bed when you first move before buying a nice set or something. Definitely recommend ... show more

    • Good bed frame. Easy assembly
Color: Black Size: King Style: 3-Step Assembly
Very easy assemble and the frame felt super sturdy. We have bought from this manufacturer before we I didn’t expect anything less. Seems like it will be very easy to break down to move when needed as well. Holds the mattress in place and fits well.

    • Strong Support with Smart Storage
Color: Black Size: Queen Style: Basic Assembly
I’m really impressed with this bed frame! It was incredibly easy to put together—everything fit perfectly and the whole setup took less than 20 minutes. I also love the under-bed storage space; it’s roomy and makes keeping my bedroom organized so much easier. Sturdy, practical, and such great value!

    • Sturdy but mattress slides around.
Color: Black Size: California King Style: Tool-free Assembly
It was easy to put together and it is very sturdy. I have been sleeping on it for a little over a month now and it hasn’t squeaked at all or made noise and I do toss and turn a lot. There is adequate room to store stuff underneath and it’s the perfect height to sit down comfortably to put shoes on. I have only one complaint/issue. The mattress slides around on top of the bed frame so easily. I find myself constantly sliding the mattress back in place. Now, this only happens when someone bumps the mattress or sits down and it slides a little. It’s really annoying and I wish the company would have included the gaskets that go on the side to keep the mattress in place. I bought a different frame recently for my son and that did include those gaskets and it makes a real difference, he never had to slide his mattress back in place. For this reason I knocked off one star. ... show more

    • Easy assembly and cheap!
Color: Black Size: Full Style: Basic Assembly
Easy to put together and great for the price. Wish there was a bit of an edge to it cause the mattress slides around on top a bit but it’s great.
