The carpet it’s on top of is sort of cheap indoor wall-to-wall. It lends itself very well to Velcro. Indeed I have a run of about 1.5 meters of some flat white Ethernet cable criss-crossed with some off that thin green garden (or maybe wires which I use it for) velcro strips helped in a few spots by the thinner Gorilla tape paralleling the cable and nothing has moved up or over. It would be hard to trip on it.
The rug is maybe 1 meter x 1.2 meters. Black rubbery bottom. I think in our last home it was sort of the 2nd rug to wipe your shoes on or take them off. Maybe because the shoe rack was on part of it it never moved anywhere in 3 years.
Here it consistently and by centimeters / inches a day it moves in only one direction (away from the door if that matters). Yesterday I foolishly thought some of the velcro in each corner would keep it in place. Nope, by today it had detached from the velcro and moved by about 6cm. No pets.
I am just after putting it back in place and using the thick Gorilla tape in the corners. I am willing to tape the entire perimeter if that’s what it takes. And I reckon it’s gonna.
We did actually flip it around yesterday when my wife saw I meant to anchor it. One corner - on opposite end from the door - had bent up enough to be a trip hazard. Such that you’d think any trips or stumbles would tend to move it back towards the door.
You can also use double-sided tape made for this purpose (I am using some currently and it has never failed). You can probably get it at almost any hardware store.
I have had this happen with numerous rugs over the years. Right now my wife has placed a semi-circular rug under my computer desk. It keeps slowly coming towards me until it blocks the wheels on my chair. Yet I cannot get it to slide back no matter what I try. I have to pick it up completely and move it.
My latest blankets do this also. I place them evenly on the bed but by morning it has slid about 6 inches to one side. However, when I flip it over it stays put in this case. I think it is a reaction to my flannel sheets.
I have two rugs that also consistently move in one direction only. Tried all sorts of things; the only thing that actually worked was nailing it to the subfloor. Until the nails came loose …
This is all because rug beating went out of style.
Beat your rugs, people. It’s not cruel, it’s necessary for them to know their place. Otherwise, they’ll get all kinds of ideas above their station, and next thing you know, they’re dating your daughter and demanding the vote.
OP, maybe time for a new rug. Get a bound rug. Preferably the type with a twill binder on the bottom. They are always heavier and stay down over carpet better.
If this thing moves again, it’s going out like the father (Coach!) does with the TV at the Motel at the end of Poltergeist.
In our previous place, it was being used as a secretary’s mat for my wife. I really do think it is sort of the “second mat” for house entry yet whatever. It also has the same kind of black rubbery frame (?) or bezel (?) about an inch wide on the edges. I just tried tugging it with enough force to move the bed and no movement. Yet. It’s trying to figure out this pesky Gorilla tape first.
