Question: What is the max size, L x W, of the rollers that can be put into these?
Document: I bought these after purchasing a bed frame off of Amazon (Serena Ultimate Series 6 Legged Super Heavy Duty King Size Metal Bed Frame With Double Rail Center Support & Wide Rug Rollers. I had been very frustrated. Despite the locking wheels on the frame, the bed still felt unstable and rolled when I would sit leaning against the wall.These castor cups instantly fixed my problem.
Sorry did not move smoothly . When they are on the rollers of the chair you can move the chair nicely, put a body in the chair the chair moves the castors stay. Sorry, If its me.
This item is great to put under the bed rollers, especially if you have tile floor. The bed won't roll. The grooves in the plastic keep the wheels in place. Better buy 2 incase they become extinct.
Our bed is a metal frame on rollers and we have a wood floor, needless to say it moved a lot... and i'm not talking about only during those &#34;special moments&#34;Got these put under the rollers and it's been perfectly stationary! No more lost pillows over night :)
Move to a house with laminate flooring and my couches had legs in the back and rollers in the front. Had a major problem with the sectional couch coming apart because it just slid or rolled across the floor. Bought these guys and now my couches stay put. I wish I had bought this product when I first moved in.
I bought a new bed on rollers looked all over for something to put under the wheels could not find anything! A guy at Walmart suggested I look on line, I put in google for something to help me and Wa La!!!! I love these coasters they work great! You get 4 in a pk so I ordered 2 packs! Who knows maybe someone will ask me and I can give as a present! Thanks so much!
I had an old frame on my queen size bed and it rolled all around the floor.Once i put these on it never moved again.And alot cheaper than a new fram.
I attached felt to these, and put them under a full size bed. The casters fit in just right. It's been about 1-2 months and the castors have not come off the cups yet.
Purchased this product for a queen size bed that sits on hardwood flooring. Works great. Always had problems with the bed moving when getting in and out of it, even with the wheels locked. The routine of moving the bed back against the wall where I wanted it was getting really old, really fast.Put these little guys on and the bed is definitely not going anywhere.
These things work great. Took me 1 minutes to left a corner at a time of my queen size bed, and put them underneath. My bed no longer rolls around. The frame only had one lock for some reason, and it was broken. I can now sit at the head of the bed against the wall and lean back, and I'm a big guy so that is a lot of force. If these things ever break I'll update my review and how long it took. Hopefully not.
Answer: no
