Kennkari Office Chair Mat for Carpet - 36"x48" Heavy Duty Vinyl Plastic Floor Protector with Lip for Rolling Computer Chairs - Perfect for Home Office, Gaming Setup & Workspace Protection on Carpeted Floors

The product meets my expectations, had to use a heat gun to unroll and get it to stay flat on carpet.Came rolled fairly tightly. Difficult to get unrolled and to KEEP unrolled. Had to find heavy items to sit on top of front and back edges to keep lying flat.I never realized all the differences for “chair” mats (wood floors, tile floors, carpet, etc..sizes, thickness, weight of person, wow!) Well, after lots of research (luckily I had lots of time at this point to do the research) I am thrilled not only with pricing, durability is awesome and no Indentations from the chair. Definitely recommend and would absolutely buy again. Thx!I did not like the product coming rolled instead of being shipped in a flat container. It would not lay flat .. we tried different things to get it lay flat but it curled. We finally disposed of it and purchased a different one at Besy Buy.. Unless you have the patience of Job do not purchase this product..The front never flat it us always rolled,tried to unroll from front still same,never recommend this product.Very hard to flattenIt is not horrible, its just not good.It will protect your carpat but if you roll on your chair that plastic will move with you slowly until it creeps against the desk leg and start curling up and you realise it once you kick your bear foot undersneath stabbing yourself with the short, too short, yet too short poi0nts underneath. This made me wonder. The sharp small teeth underneath are probably tearing through my carpet instead of being held in place.The plastic is not very transparent and your chair wont roll well.The worst part is that, if you use it on carpet and you sit on your chair, you press down the plastic and you basically root yourself and have to get out the chair and move it, making it worse than carpet.But hey, at least it protect my carpet, maybe.
