"100% PURE MEMORY FOAM: Our memory foam is 100% pure with no additives and is made of the exact same material as the world's leading memory foam manufacturers. Our foot rest is formulated specifically for the weight of your feet and legs with a firm structure that compresses just enough to conform to the shape of your feet giving you that “everlasting comfort”. Our desk foot rest is perfect for the office desk, airplane, or couch. ORTHOPEDIC "TEARDROP" DESIGN: Unlike standard under desk foot rests that are half moon shaped, our signature “teardrop” structure and orthopedic design places your feet and legs in a more comfortable and ergonomically correct position. The angle and increased surface area of the teardrop design supports your plantar fascia and helps keep the cushion in place. HEAT RESPONSIVE - The advanced memory foam pillow responds to the heat of your body to mold perfectly to the shape of your feet. The memory foam compresses and cushions just enough to provide you with that Everlasting Comfort yet keeps its shape to support your plantar fascia, heel, toes, and entire foot. NON-SLIP BOTTOM: The cover is equipped with a non-slip bottom so the footrest always stays in place. The super soft velour cover is extremely soft and durable and is removable and machine washable. LIFETIME REPLACEMENT GUARANTEE: We provide the best customer experience possible. If anything goes wrong, we've got your back, or shall we say...feet. After Achilles tendon surgery, it is important to keep the foot and ankle in a stable and immobile position and our support pillow provides cushioning and support, preventing excessive movement and protecting the surgical site. It aids in the healing process by reducing strain and stress on the repaired tendon."
