I've looked at those online. My biggest concern is occasionally cleaning underneath them and potential damage if it's dropped. I had a plastic mat that worked well for 20 yrs so when it needed replacing I bought another one and regretted it as the quality was no longer there. I bought a heavy carpet mat and it's working well although my chair doesn't roll as easy on it as it did over plastic.

 

I have berber carpet in my office. Wife gotta free roller chair from her job years ago. It has zero issues moving around.
FWIW...Don.

 

I would be worried about breakage too, but the reviews don't substantiate that is a significant concern.
They mention thin pile carpeting is a suitable substrate, but the carpet is not so much the concern, it would be soft padding underneath it (are they playing word games?)
It's not so much dropping a coffee cup to worry about, it's the point loads from the chair feet. If your chair has 5 plastic rollers, like in the picture, you might be pretty safe.

Just that that particular mat is missing the extension that goes under the desk. In time, your feet will visibly wear out the carpet under the desk.

 

Just be wary of the edges. If your chair were to slip off and the metal hits the edge of the glass, you will be vacuuming up beads of glass for a week. The edge is the nemesis of tempered glass.

 

txs all, @SPS-1 I have a 5 plastic roller chair, although I am also going to be replacing the chair as well.
am not worried about wearing out carpet, my carpet is not in a good state anyway, (dirty-stained) but not worn.
The reviews all seem to say its good.
I don't mind plastic even if I have to replace, but a lot of the plastic ones I've heard about, get divots in them after sitting on them for a while, then you can move the chair off it ,
at the moment its a bit of friction to move the chair, "not an awful lot but hmm yeah"
My desk is not wider (longer?) so be nice to roll from one side to the other or push myself easily back and forth.

I'm also wondering now if it would make it too "wobbly" ? too "slidy" so if I sit on it will it slide away, which is the other end of the "Not able to move" the chair.
I'd need to focus on not moving around too much.

How about getting some squares or a run of click wood or vynal flooring

HMMM, now I'm not any closer, plastic sounds good but dont wanna screw around with dents

I used to have an office with carpet.
Plastic never made divots, but the casters on the soft carpet would eventually fatigue the plastic mats.
I never tried the glass, but otherwise I found the best bet was a piece of 1/4" hardboard, cut to shape. It would have been pretty slippery also, but was not a problem.
Even the hardboard will eventually fatigue, but gives far more life than plastic.[/USER][/QUOTE]

 

maybe just get a new chair anyway and live with it

 

We've had one of those Staples plastic desk mat for 2 or 3 years now and no problems.

 

Probably depends on how good the tempering is. Car windows are pretty amazing. Glass tables are usually very good. Rounded corners are a good sign. I'd bet the biggest risk is rolling over a grain of sand just right and that shattering it- like throwing some spark plug ceramic at a car window. You could get some window tint and tint the bottom. If it does shatter, tint is surprisingly good at keeping all the pieces glued together.

There are also direct replacement office char wheels that are basically roller blade wheels that might be safer for glass.

I've used some particle board type stuff in the past that lasted several years. Like peg board but without the holes.

 

The only thing about the Car windows,
your not putting in on the ground and sitting on a chair on it, in normal use, unless something sharp gets thrown at it, or hammer put to it.

still giving me the heebee jeebees thinking about sitting on it.
I mean the demo looks great and no bad reviews

All the plastic mats I've seen inc. Staples all say that the chaiors get bogged down in divots

likng the particle board idea

I'm not worried about wear and tear even a year, I'll just expense another one, its the getting stuck in it after sitting down a few hours thats a bit peeving me

 

just realized I have some squares of flooring in my basement, with slots in them, think they were used for something my basement build by the builders,
There small squares which I can easily bring up and test out, could even cover up with some vinal covering, there quite thick so I might bang/catch my toes on them

not sure of the namne, but they have long interlocking edges

Or maybe I'l look at a rubber or similar interlocking tile or even a few interlocking garage floor tiles

I'll report back

 

yeah I'm onto something, going to go have a rummage around the house
will report back

 

@Chonks NICE !!!

 

@Chonks I got a set of "rollerblade" wheels, about 40 bucks from amazon, made a big difference. lifts the chair up an inch or so, but I also noticed it still kinda sticks, but now realised that the carpet is like creased, not sure how, just use, different things stuck on there, so if I want glide free, I need that tempered glass thnigy or to pull the carpet, not sure how I can ( see pic) but either way, def I would say 80% better
I believe a single narrow wheel is easier to roll on carpet than 2 wider ones
(stock photo not exact item)

 

actually, I just noticed, the carpet has little runs in intervals in several places, all running with the line of I guess the floorboards, so I guess bad underlayment or just wear and tear, carpet in my room is like from 2006, so 17 years old

only fix is replacement or the glass thingy or put down some vinal hard floor/lino or similar, guess I could tack it down. not sure how odd it would look

 

You could go all in, take up the carpet where the desk goes, and install hard flooring. Not sure about the underlayment thing though. I could see those roller blade wheels being harder on the carpet... being narrower than the plastic.

 

Cut the carpet back to a reasonable amount to allow for a good push back, stretch it to fit in malleable carpet transitions nailed to the floor, tap the edge down to hold the carpet. Put some Ditra down and tile the area.

 

I have a very thick clear plastic mat under my chair, slick as snot, chair rolls too easily sometimes. My concern with the one you posted … the size. 3x4 ft. Mark that out on your floor with painters tape, it's so small you can’t roll the chair around. The spread of your wheels is probably 2 ft.

 

Here is a thread about a chair mat i made for my daughter.

https://www.diychatroom.com/threads/office-chair-mat.708301/post-6369989

 

I really love that eddie, I'm thinking that would be a better idea than a mat, which relies on carpet and will divot
looks like something I can make, I wouldnt glue it though, I'd tack it down with some nails, or nailgun.
"next project coming up "

 

, I'd tack it down with some nails, or nailgun.

You need to rethink that. The substrate will only be 1/2” thick at the mist, and you can’t have nail points exposed on the other side to snag the carpet. And none of the lvt or laminate flooring is intended to be nailed.

 

"My concern with the one you posted … the size. 3x4 ft. Mark that out on your floor with painters tape, it's so small you can’t roll the chair around. "

solid point

 

mind you......

if I ever had to replace the carpet, the whole thing would come up anyway,

my concern is if I have to move the desk, or put something else there, that mat is stuck there

 

You’re missing something. I built a separate chair mat that sits loosly on top of the carpet. It doesn’t replace the carpet, it isn’t fastened down. It’s the same concept as the glass mat you proposed to buy … you can pick it up and move it.

 

anyway, time yet for this project but at least I have food for thought

 

I would just buy a couple of boxes of 10mm+ click-lock laminate flooring, assemble the size you want, and then run a router with a roundover bit around the edges.

 

so you glued them back to back ? because they are clickers so otherwise they would break and move, or you glued them to a piece of hardboard or something, you say you glued them down, but to what ? the flooring you glued to a piece of wood, ? it really looks good, I like it

 

The bottom layer is a piece of 1/2” plywood. I cut it to shape to fit under the desk. Then i glued lvt planks to it. Yes they click together, but i glued them to the plywood. Then i trimmed the lvt.

 

cool makes sense, !
