Description

The SmartBase checks off a lot of boxes on a bed frame wish list. Excellent mattress support without a box spring? Check. An abundance of underbed storage space? Check. Assembly that’s no sweat? Check! Frankly, we’re not surprised that so many happy customers have traded in their two-piece box spring and bed frame sets for this reinforced steel base. It’s designed with a metal platform that you can rest your memory foam, latex or spring mattress directly on top of for extended mattress life. It’s also engineered with multiple support legs for maximum stability and squeak-free use. Plus, those legs have plastic caps at the ends to protect your floors from unnecessary scratches. With swift assembly that only requires your own two hands and a 5-year worry-free warranty included, this extraordinary foundation is what we call a win-win.

    • 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 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!

    • Difficult to put together but seems sturdy once it's put together
Color: Black Size: Full Style: Basic Assembly
The frame itself seems to be of good, sturdy quality and my step son loves it. He says that it sleeps well and he feels much better supported than he did with traditional box springs. I took a star off because of the difficulty I had putting it together. The instructions ARE simple and straight forward if you take your time to examine the diagrams thoroughly, but the problem was with the middle bars and the screw holes not aligning properly. I was able to manage getting it put together, but not before I bruised my hand up and ruined a couple of can opener cloths to get it put together. I don't know that I would purchase it again if it meant fighting with the alignment of the middle bars again, no matter how reasonable the price is. ... 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

Very comfortable. Easy to assemble which is important for me because I hate putting things together. Looks good in my room and had it for years now. Great price. Very stable also. I was afraid of it collapsing during certain events.

This is the first time I got this 14" full sized bed platform for my new full sized mattress because I wanted one without needing to purchase a box spring. I can say that after a couple days I am very pleased and satisfied with what I got. This bed platform was very easy to set up. I did it all by myself with no help. No wasting time trying to put the legs and slats together because this comes in practically two pieces. All I had to do was to follow the instructions and put the screws in for the legs and join the two metal platforms together. It is very stable on my carpet floor and is very sturdy now that I have my mattress and comforter on top. I'm only 5'0" and about 120 lbs so I don't see this platform possibly bending or collapsing from my regular use. Even if I use the bed with a heavier person on there I think it is still very stable. I have not heard any squeaking as I was rolling around and moving on my bed. I also like that they included some nonslip adhesive strips as it helped keep my bed skirt in place while I placed my new mattress on top. I didn't get a headboard so I'm not sure how easy it is to install any headboard outside of the brand. I am currently renting a room in a house and storage space has been pretty limited to me. I was able to fit a lot of things underneath the smartbase, including my shoes, styrofoam cooler, some clothes, bags, and clean containers and food jars. Pretty much any storage container under 13" in height can fit underneath the base. The diagonal bars that hold the legs in place and legs in the middle of the base are in the way, so if you have any wide and tall storage containers then you have to be a little careful. If you need to fit standard storage containers, I would recommend getting the taller smartbase such as the 16" or 18". For someone of my height with a 14" base plus 8” mattress and a 2" mattress topper, I did not have trouble getting on and off of my bed. My feet dangle about 2-3" off the ground now. I could imagine that any smartbase greater than 14" would give my bed a lot of height. Overall I am very happy that I got this base. You can probably tell that the black cat in one of my pictures is very pleased, too. I would argue that even if you don't need much bed storage space, this is a great bedroom essential to have because it is easy for one person to put together, dismantle, and move and you can easily add height to your bed without sacrificing its stability and sturdiness. And with a good bed skirt and comforter, you'll forget that you even have a metal bed platform! ... show more
