Like peanut butter and jelly or milk and cookies, a Cubii elliptical is not complete without a Cubii Floor Mat! This mat both looks great and works great by protecting your floor and preventing your Cubii elliptical from sliding. Its dual non-slip texture keeps your elliptical in the perfect position no matter how quickly you pedal.This Cubii floor mat is made for use indoors on carpeted and hard surfaces and should not be used outdoors. The Cubii Floor Mat measures 20" x 26.75" in size and is 4mm thick. Made of premium thermoplastic rubber, this mat can be wiped clean without the fear of damage.The Cubii Elliptical Mats come tightly rolled to prevent any damage during shipping. To help remove the curl from the corners of the mat, unroll the mat, then flip it over and reroll the mat. Keep it rolled up with a rubber band and check it every 5 minutes until the previously upturned (curled) corners are laying as flat as desired.
