It is expensive. The cleats aren't nearly big enough for the thickness of carpet this is supposed to work for (3/8") so it slides around. It works otherwise with no cracking yet. It flexes a lot too so you need to rotate the wheels periodically so you don't create divots in the mat. Not sure it's worth the premium given it won't stay put and still flexes a lot.
This mat looks fine grippers on the bottom work well size is fine. BUT it’s very soft plastic so your chair wheels press into it and make it very difficult to roll or move around. It’s not at all like rolling on a hard surface floor. This is on very low berber-like carpet. Disappointed.
Purchased this mat to protect the wood floor at my house. Works PERFECTLY. This is smooth on both sides so is gentle on the floor . . . the size is right for moving back and forth and side to side while never leaving the mat. Would definitely buy again.
The mat is exactly what we needed to protect the carpet under our office chair. It is a great size good quality and stays in position. It was delivered quickly!
