Once it is placed on carpet (medium depth) and a chair and person is sat on it, the edges turn up and become a tripping hazard.

It doesn't lay flat and rolls up on the edges making a trip hazard, I have fell and tripped on this lousy mat

Causing a huge tripping hazard

Original mat I received was too thin and caused a tripping hazard.

This is just a sheet of plastic which if used on anything but a concrete floor will create a serious trip hazard

Edges bend up from weight of occupied chair and become a tripping hazard.

I bought it in June and noticed last week that the edges bend upward and are a tripping hazard.

Over time, the edges curl up, causing a tripping hazard, and catching the wheels of my office chair whenever I inadvertently roll off of the mat.

As another reviewer mentioned, this thing is also an extreme tripped hazard, as the corners have randomly curled up which not only gets my chair wheel stuck over 10x a day, but also makes me nearly fall flat on my face half the time when getting up from my desk

Its not become a tripping hazard and we don't recommend it.

Has already creaked and rises up on the edges becoming a tripping hazard.

It curls up at the edges and produces both a tripping hazard, and a rolling hazard

The edges did not lie flat and it was a tripping hazard

Also, the edges continue to flip up, no matter what i do, which causes a huge trip hazard

It also sits high enough to be a tripping hazard for me as I no longer can lift my feet high when I walk

This becomes a tripping hazard after a couple of months-

This chair mat is very weak, the corners bend up, creating a real tripping hazard.

They curl up at the corners and become a tripping hazard

so it's a tripping hazard.

Now it is a tripping hazard and a pain.

but it does the job for what I'm needing, as long as I can get around the tripping hazard that this mat presents.

Corners and edges of mat curl up and present a tripping hazard.

It started t crack within a week of use

the only positive I can give is how it was shipped, being that it wasn't rolled up.

and I shouldn't have to jury-rig something to get it to work as it should in the first place

I was looking for something to slow down my chair wheels so chair would not constantly want to roll like a flash and dump me out as it went... and this is not that kind of pad.

so it doesn't look as nice as in the picture.

Recommend A+++.

, thoughwhen we hit our feet on the upturned edge it doesn't hurt as much as it used to.standing in a half squat over the chair while looking down at the one caster that has rolled onto the carpet to make sure that it rolls back on instead of being caught below has become second nature.it's what we deserve

Works as you'd expect.
