I love my big mat. I use it all the time. Right now it is on my dining room table because I am renovating my sewing space to include a designated cutting table. I have stored it behind my hutch and it has been fine for years. My hutch sits very close to the wall, so there is not problem with bending. However, if that ever happens, I would put it out in the hot sun for a short time to weight it down with something heavy to straigten it out again. This has worked for me in the past on another mat.
