Expert Reviews

What experts liked

The overall steel framework will always provide a stable base for your mattress and is sturdy enough to carry substantial amounts of weight.
With the steel frames and wire, the bed frame has a wide slat plus recessed legs, which offer adequate support and stability needed.
Tons of under bed storage, easy to assemble and disassemble, frame keeps things quiet, super affordable price point
Another bonus with this platform steel slat frame and box spring combination (14 inches tall) is that it provides ample room for additional storage underneath the mattress.
Leg caps to protect floor form scuffing
It didn’t squeak, it didn’t creak, and the mattress stayed exactly where I put it—there are these sticky strips included with the package (essentially giant pieces of nonstick tape) that ensure your mattress won’t slide around, but so far I haven’t needed them.
To prevent the chances of any accidents, the corners are rounded so any collisions will be softer.
It’s so supportive that one reviewer says it helped them revive an old mattress.
This bed frame from Zinus is lightweight and easy to assemble. It’s compatible with SmartBase brackets for those who wish to use the frame with a headboard.

What experts didn't like

Extra purchase required for installation of the headboard.
Some mattresses may slip, no clear indication of how much weight it can hold
Better suited for memory foam mattresses
The finished product isn’t incredibly attractive.
Too much movement can damage the steel bars


Bed frames are the foundation to a good night’s sleep. So before you make a purchase, check this guide for suggestions of things to look for in an ideal frame.

Start by reviewing the type of material the bed frame is constructed out of. Many are made from a sturdy steel, while others feature solid wood slats. Still, there are some models out there that are made from cheap materials, including plastic, and these units won’t hold up under the pressure of everyday use.

Next, decide if you’d like your bed to have a headboard. Some models come with a headboard, while others might not come with a headboard, but allow for attaching to one with as long as you have the appropriate hardware.

If you live in a small apartment or home, you’ll also want to take storage space into consideration. Look for a frame that leaves 13-inches of space underneath for storing everything from photo albums to your wedding dress.

The type of mattress you plan to use with the bed frame is also important. There are styles of bed frames that work with memory foam, traditional spring and hybrid mattresses. Additionally, most frames can handle a box spring. Not all bed frames are designed for both a box spring and a mattress.

Review the product label for the words “noise-free.” You don’t want to spend good money on a bed frame that creaks every time you roll over in the middle of the night. Instead of falling right back to sleep, you’ll be jolted awake.

Finally, check to see how easy or complex the bed frame is to assemble. Some models require the use of your own tools, while others don’t need any tools at all. If you have a handyman in your home, this may not be an issue.
