Queen

King

Frame is well-constructed and robust in design.

Can be snug, but may not fit larger beds accurately.

Can be sturdy, but also prone to tearing.

Setup is typically completed in a short amount of time.

Excellent choice but not what I was expecting. It was not the traditional box spring that is bulky to carry. It came in a mid-size rectangular box and the tool to put it together. It was lightweight and easy to assemble. It fit my granddaughter's bed, nice and comfortable, and she loves it.

Excellent choice

This frame was just what was needed to install a box frame for a bedroom located in our finished basement. Would have never been able to successfully move a traditional box frame into the basement and was so relieved to discover that a product like this existed. Frame is sturdy and was not difficult to assemble. JP

Practical Metal Box Frame

walmart.com

Got this for my brother who is hard on EVERYTHING! Holding up great for the last 3 months or so it's been up. Very heavy in box and a lot of parts to put together, but not a difficult build other than a lot of twisting nuts and bolts in! Overall, I recommend this product highly, as it's sturdy!

Completely satisfied

There is a main frame that opens up and then all the different bars and slats go in place. The assembly isnt hard, but you do need to pay attention to the written and visual instructions . Very pleased with the box frame. It fit perfectly on our queen size bed frame without any issues.

I was expecting a put together full boxspring, but it came in a little box which scared me at first and I was having somebody come to just put the full boxspring on the bed, but that person then had to pay them to put it together. I wasn't expecting that Once it was done the guy who did it was very good. It didn't take too long, but it wasn't what I was expecting and but once it was done, he put it on the bed. We put the mattress and went on and proceeded and person slept on. It said that it was a good sleep so I have to think that you know it seems sturdy and everything else so I would not give it bad review. Just be aware that you're gonna have to put all those little strips together

Had  to be put together!

If you do not have supports going across you rails, don't buy. I had to build individual stands under it to keep it from callapsing. It is very light weight. it does hold up, but it still leaves me skeptical with it. If it's just sitting on the floor, it will definitely lift the mattress off the floor.

I knew I had to assemble to frame.  I was expecting a little more metal at the joints.  The lack of metal reinforcement at the joints allows the center of the frame to sag in the middle when weight is applied.  I made an easy fix.  I built a wooden box to place underneath the mattress.  The box made the frame extremely sturdy.  Without the box underneath, I would not be able to sleep on the bed.

Flimsy in the middle

Easy enough to assemble. Went to place on the bed frame and it's too big! Yes the bed frame is for a king which I purchased. So I took it off put it directly on the floor then put the king mattress on it and it's roughly 3 to 6 inches too wide! So either I assembled it wrong. Which I followed the instructions, so doubtful or their measurements are off. It's too much of a hassle to disassemble and gather all the pieces and return so now I'm stuck with this and having to place the mattress in a weird position of it being centered but there being a 3 inch or so bit of box spring on each side lol maybe one day when I'm bored and have more time I'll take it apart and re assemble it.

Larger then a king mattress

Defective. Period. The holes for the b-type M6x19 screws (36 holes!) are too large. You cannot attach the middle support beams 3, 6, 7 and maybe other parts. Half way through assembly and the holes are too large. The M6x19 screws do not come with nuts. I am now going to purchase replacement screws with nuts to be able to still use it. It looks rather sturdy and I had plans to purchase more of these for different beds I have. But you should never trust a company that makes so many mistakes with manufacturing like this. I have never had a product in my life with consistent errors across so many holes. Either other reviews are fake and this company is a joke or I got a very rare lemon.

Defective. Avoid.

It was a scary experience, you read the manual and tighten the screw expecting the parts to be screwed. They are literally loose ends all across. 
We continued to build the entire box frame thinking eventually it should all makes sense and when we lifted it up, they all started to fall on our feet %26 arms.

Terrible and hazardous
