Bed Risers with Adjustable Screw Clamp, Fits Thickness of Furniture Frame from 0 to 1.5 Inch, Furniture Risers 4 Inch Heavy Duty Risers for Table Cabinet Support up to 5000lbs (4Pack, Black)

Sturdy and lock into place. Did what I needed but was a bit high so ordered different ones. But highly recommend.

They worked just like I wanted. Stand needed to be taller, had small legs so we added a little support to them. They are well made and somewhat adjustable but it really depends on your furniture. I would differently buy them again.

For some reason, I purchased these without realizing they were only 4 inches tall. I returned them, because I needed more height.That being said, these risers look like the would be perfect for my metal bed frame. These are the only ones I found that seem like they would SAFELY raise my bed. I just wish they came taller.These risers seem like they would work amazingly well, if you only need an extra 4 inches of lift.

I got this for to raise a twin bed and they work ok. I’m a little afraid that I will become a wobbly when a heavy person sleeps in the bed but so far it has hold up pretty well.

I bought these to raise a desk hutch high enough for a full-seize monitor to fit underneath it. Most risers just have a channel the item being raised sits into, with nothing to secure it. That's fine for a bed riser, when the weight of the bed is going to keep it stable on the riser channel. With something like a desk hutch, it can get top-heavy really fast if it's just sitting on top of a block. Two things that make these increadibly helpful: 1) they are rectangular, not square. This allows the side of the hutch to fully slot down into the channel, which is far deeper than most risers offer; and, 2) it has screws to tighten the riser to whatever it is holding. We put two on each side of the desk hutch and it was the perfect height and super stable.

This maybe fine for light weight low height furniture but not for 5 feet tall furniture. We tried it for a few months and it was wobbly. Now we removed it and the return window has expired. So it's just sitting in a box. Waste of time.

I bought a computer chair that hit all the marks except at it’s highest height, was a bit too short for my desk. After a week of neck cramps, I searched for a way to raise it. It has no wheels and couldn’t find something that I could screw in…these have been a lifesaver! Super easy to install and now I can work in peace!

Loved the narrow profile but the clamps break easily, which makes the legs of the bed shift around a little. Sometimes a riser slips so much.it falls on the side, leaving that leg unsupported. I'm afraid I'll break my bed frame after using these only 3 months. I've gotten used to constantly adjusting them before I get in bed but it's annoying so I'll be looking for a different product
