Adjustable Bed Support Legs 2PCS (7.87"-13"), Heavy Duty Bed Frame Support with 4 Anti-Shake Rings, Tool-Free Odorless for Home/Wooden Furniture

It's pretty good, but its not stable enough. It doesnt grip the floor or the bottom of the bed so if the bed slides at all it will fall over

These do the job. They are easy to assemble and relatively easy to adjust. They are sturdy on the floor. They add a decent amount of support to my king size bed.

I needed something to lift a chair higher and got these. They immediately broke. Don't waste your money.

These worked great as stabilizers for my platform bed. I bought an old one used and although it is sturdy, I don't think it was made for the super heavy mattresses that are available these days. The area in the middle needed more support. They were easy to install, and adjusted to the right height. My bed is completely sturdy and stable now. No more worrying that it might break and dump me on the floor in the middle of the night! Note that these are physically pretty chunky and large, so if you can see under the bed they may not be the right thing for you.

Not hold weight.broken right away.
