So, we've been looking around for kitchen mats lately. And we actually like the unlikely candidate, Gel Pro Chef's Mat when we take a closer look at it. It's a fatter alternative to thin (and expensive) Chilewich mats. And we like their woven appearance.
The mats are a residential version of commercial kitchen fatigue mats. They're supposed to relieve lower back pain and are 100% cleanable. Two different sizes are available: 20x36 for $100 and 20x72 for $200.
