When you order from Vitrazza, you can have confidence that we're taking care of every detail. We want you to have a great experience receiving your new Glass Chair Mat. So, we include our curated 'Care Pack’. Here's what is included: Inside you'll find our Transferable Lifetime Warranty, handling tips, cleaning tips, and more. The Vitrazza Stabil-a-dot Bumper System enables your new Glass Chair Mat to work on any type of flooring. And it helps resist creeping. The system includes 3 different sets of bumpers; one labeled ‘hard surface’, one labeled 'carpet', and the other labeled 'Super-Size" (for use on plush and high-pile carpets). Choose the set that applies to your floor and apply those bumpers to the bottom of the mat (we include a diagram). We give you a valuable Easy Lift Tool which customers use to slip under the mat when they want to lift or move it. We don't want you to use metal tools such as screwdrivers.
