Excellent job by staples delivery was next day and the driver rang the front door bell for delivery. Social distancing was practiced no physic contact items placed at front door. The mats are on the thin side compared to the units being replaced but for the price they should last a while. The old ones were all cracked and starting to break apart. These might not be good for deep pile as the chair does tend to sink in a little on regular carpet.
I feel like I"m hitting potholes and have to fight to get out of them to roll around. I have a med/low pile carpet but chair sinks in and I'm constantly stuck to roll around on this.
