Question: will the coasters keep the bed from moving if there are tile floors?i
Document: There wasn't a lot to pick from. My mom needed something to keep her bed from moving on the hardwood floor and this does it. Simple, cheap and easy to install.
Use under my 4 poster bed to keep it from sliding on tile floor. They're a nice size and the large casters on my bed fit nicely.
these caster cups are very functional: they're substantial enough to keep the bed from moving & damaging our hardwood floor.also, the dark brown color blends into the floor.
Casters will save your wood floors! These are great for using under heavy furniture. They are also good to keep recliners and rockers from sliding on wood or tile floors
Saw a bunch of reviews stating how well these work on hard wood floors. However, we used these for a love seat that kept sliding around on a tile floor. Long story short, the grip is absolutely great.On top of being able to plop down in the love seat without it moving or scooting a inch, you can even sit on the floor and lean back against it and it won't budge.Very satisfied with this little item and the price.
The coasters will save my tile floor. They are larger thank i thought, but they will work just fine. Thank you again.
When we sat down in our chairs on our tile floor they slid badly - these coasters have completely eliminated the problem. The only ones I could find in the hardware stores were plastic and didn't work, these will do the job.
I have a large leather sofa on a tile floor. Every time someone sat down it would slide. I bought four of these couch coasters, and the couch hasn't moved an inch, even with teenagers plopping into it.
I bought these to keep my daughter's bed from sliding around on the wood floors. These little squares did the trick perfectly.
Didn't quite provide enough lift to allow my Roomba underneath but that is in no way the fault of the product. Just had to put a little something extra under there. Keeps the bed from moving around on the hard floor though!
Answer: yes
