Bed Stopper & Furnitures Stopper – Caster Cups fits to All Wheels of Furniture, Sofas, Beds, Chairs – Furniture Cups Made up of Solid Silicone and Prevents Scratches (4 Pack（Black）)

These are really nice. They stop the rollers without being too big

These work great on my rolling ottoman!! We removed the rug from under the couch/ottoman, and the ottoman was rolling all over the place making it insane for my dog. These stopped all movement and seem to be working perfectly!

This was a perfect fit for the trundle unit that goes under my daybed. Keeps the trundle from rolling around.

Not as -non slip- as I was hoping underneath. Unless full weight is directed downward, vs lateral, may still slide a little. Does provide good barrier between wheel and floor. Solid quality though.

I purchased these for my elderly grandfather’s bed because every time he went to get in it, the bed would roll on the hardwood floor. It became very unsafe. I wasn’t sure if these would work or not because they look so small. However I was wrong! These little things work so good! The bed has 8 wheels and I used 6 of these things and the bed doesn’t move an inch! They are ridiculously easy to install as long as you can lift the bed to slip these under the wheels. They have a very strong grip and work just as advertised. If you need to keep your bed from rolling or anything else with wheels to stay in place, these things work great!

Stops the bed from moving on hardwood floors. Good quality and price

Bed frame kept sliding on laminate flooring at assisted living facility and didn’t want to put a rug down, this did the trick! Bed stays put and no more worrying if the bed would slide or be pushed, possibly causing a fall

We have wood flooring and our bed frame came with rollers, so keeping the bed in one place even with minor movement quickly became an issue. For a year, every night before I went to bed and often a couple times beforehand, I had to push the bed back up only for it to roll back down and cause me serious neck pain issues from the pillow sliding back between the mattress and headboard. I searched for solutions and found these bed/furniture stoppers. They installed really easily even with a heavy bed. Simply lifted the corner, slid it under the wheel and voila! No more sliding! No more neck pain! I only had to use two of the four which I placed on the bottom wheels. The extra two I placed on my daughters bed. It's seems crazy that something so simple would make such a difference. But they really did. They are made of rubber or something like it and are very durable and slide proof at least on hard wood floors which is where I have mine. I don't have other flooring but i can imagine it would work similarly on other flooring types.
