Staying on your feet has never been more comfortable—whether you're prepping food for your next dinner party, spending a weekend baking or washing dishes after, these anti-fatigue mats conform to the shape of your feet and support your arches for relief of back, leg and foot discomfort. The Cumulus9 proprietary Multi-Core technology is environmentally friendly and non-toxic, providing a multi-layer cushioning. The soft upper layer cushions your feet luxuriously, while the lower layer provides soothing support. Each mat is designed with no-curl edges and stay-flat memory tech to reduce tripping hazards while the non-slip bottom keeps mat in place. The long-lasting and durable surface is anti-microbial, waterproof, resistant to stains, abrasions and punctures. Finished in an attractive basket-weave texture in three convenient sizes. Standard mat is 20" x 36" , island area is 26" x 48", and island area runner is 26" x 72". All are 5/8" thick. Great for bathrooms, laundry and garage too! Hand wash.
