I ordered two floor mats in size 90 x 120 cm. Delivery was very quick, I had the mats Thursday ordered and on Monday I found her in the office. The mats were rolled up to, but this was no problem at all; they have not buckled after opening. We use the protective mats at the office, where daily round slipped to spend at least 8 hours. We have a laminate floor. The mats protect the floor effectively and it can stay comfortably on the mat with the office chair roll back and forth.
