AmazonBasics Premium Anti-Fati

Highly recommended for comfort but only in non-traffic areas because the corners curl up about 2" and the center of the edges lift about 3/4". I bought my mat in 2018 but curling still seems to be a problem based on more recent purchase reviews. I purchased this mat in 2018 for standing at my work/personal desk, and I have hit my foot on the curled corners or edges less than five times in 6 years. I habitually step over the met edge (the center edge lift is about 3/4") when arriving at the mat so tripping is not a concern considering I walk to and from my personal/work desk 20-30 times a day going between the kitchen, bathroom, etc (6 years times 52 weeks a year times 7 days a week times 20 arrivals a day is about 1 foot hit for every 8500 arrivals - I use this mat at my desk which is for work and for personal use so I use it everyday, several hours a day). Several times I rolled the mat top-side-out - it's hard to roll this mat - to try and get the edges/corners to lay down. Once I rolled it and held it down with the weight of my 70lb office chair for several days but after a few days the corners recurled. This mat shipped to me rolled bottom-side-out and has never laid perfectly flat. The only reason why I am replacing this mat is because my wife occasionally (rarely) comes into my office to look at my monitor and more often than not she hits her foot on the curled mat edge or corner. She considers this a tripping hazard. Even though no one has ever stumbled, she recently asked me to find another mat. Based on the searching for 'curl' in reviews, I am buying a GelPro elite mat (it's nearly 4x the cost but I couldn't find any $50-$90 mat where people left 4-5 star reviews while mentioning 'curl' like the GelPro elite). This mat has been comfortable with socks for day long work/personal use for years. I try not to stand for more than 30 minutes at a time but sometimes I stand for 2-3 hours in place, slightly and occasionally shifting around my weight on my legs and or walking in place for a few seconds every few minutes.
