Premium Bamboo Chair Mat for Hardwood Floors - 5mm Thick, Anti-Slip & Heavy Duty - Office & Home Floor Protector for Desks, Workstations & Home Offices - Anji Mountain Durable Chairmat

My girlfriend pointed me to these chairmats after we debated on how to handle the situation for my home office which has hardwood floors. I wanted to a chair with wheels because they present a more ergonomic option for me and since I have a bad back it was paramount that I find a way to get a wheeled chair for my office without scratching the crap out of the wood floors (a moot point now that our dogs have basically clawed it to death) and so I bought this in the hope that A) it would match the hard wood floors and sort of blend in and B) I could find something that could lay on the hard wood floors without those prickly bottoms that all chairmats have for carpeted floors as that obviously would tear up the hard wood floors.Well, sad to say I was off on wish A but what can you expect, there's so many types of wood that I would imagine it impossible to find one. But point B was a success, the bottom of this chairmat is actually a rug, it grips the floor perfectly, it's impossible to move when I'm on the chair or even when i try to sweep it to a different spot with my foot. Very sturdy, can be rolled up and moved if you have it in a public space like I do in my living room and when I have company over. Comes with a green bag (like those recyclable bags for groceries at Trader Joe's) for storage.I'm very happy I found these, they are awesome, hope it lasts me for a long time!
