Hi Amanda,
Thank you for your feedback on our Cleartex Revolutionmat, we are very sorry to hear that the edges of this mat are curling and creating a trip hazard. This mat is designed for use on hard floors only, if placed on carpet the centre of the mat may begin to sink into the carpet pile and the edges may lift. In this case, please can we kindly ask that you send some photos of your mat to our customer services team who can investigate this issue further? You can email us at customerservice@floortexllc.com or you can call us on 615-208-9697. We apologise for the negative experience that you have had with this mat and we hope that you will still consider Floortex for your future chair mat needs.
Thank you,
-Eleanor.
