4Pcs Adjustable Height Bed Frame Support Leg, Extra Sturdy Steel Bed Frame Support Legs with Wider Rubber Base, More Stable/Quieter, Bed Slat Reinforcement Kit for King/Queen Bed (5"-8.6")

Super easy to install. Didn't require drilling into the wood mattress support slats. The middle of our mattress was sinking, and these have fixed the issue. Couldn't be happier. Height is adjustable. Just what we needed.

Got them but they were not tall enough seems to have a firm hold

Easy Installation!! But I “assumed” the wrong length and now I have to reorder the correct length/ height and try again

Bought these for additional support on our king size bed set. Our bed only had 2 center support legs which made me nervous so I bought these for peace of mind. It took less than 2 min to put them in place (no tools needed) and it felt secure afterward. Worth the money!

Saved me purchasing a new bed frame. Easy to install Very pleased with the craftsmanship.

I thought it was going to be short but in reality got the perfect size to adjust my bed height

Nothing to complain about, helps support a previously broken box spring that I had fixed but still had a lot of give to the middle. Not much can go wrong, worst part of doing this was crawling under the bed with low clearance.

I had a support leg break during a move so I have been looking for something like this. I tried one that is just a leg and it fell over pretty fast. This one however, bolts onto the frame so it won't be moving.
