Tuft & Needle Kin Medium 12" Twin Adaptive Foam Mattress in a Box + Twin Waterproof Mattress Protector + 2 Standard Down Alternative Pillows

Experience the perfect balance of comfort, support, and cooling with the Amazon-exclusive Tuft & Needle Kin 12” Medium Foam mattress. Designed to provide innovative cooling, responsive pressure relief, and a bounce-back feel, this mattress lets you sink into sleep without sinking into the mattress itself. T&N Adaptive foam contours to your body while keeping you lifted, and a gel-infused transition layer provides additional cooling and comfort for a truly restful night. Thicker layers* of Adaptive foam, combined with a durable foam core, ensure lasting support and comfort. Crafted with GreenGuard Gold and CertiPUR-US certified foams for better indoor air quality, the Kin 12” Foam mattress is compressed in a box for convenient setup and backed by a 100-Night Sleep Trial and 10-Year Limited Warranty. Please allow two weeks for the mattress to fully break in and air out. (*Compared to the 10” Kin Foam mattress.) To protect and enhance your mattress, the machine-washable Tuft & Needle mattress cover offers waterproof performance without sacrificing comfort. Its soft, breathable top layer mimics the feel of the mattress itself, while the deep-pocket, fitted-sheet design securely fits mattresses up to 14 inches deep—including California King, King, Queen, Full, Twin, and Twin XL sizes. Enjoy the convenience of free delivery and the confidence of a 100-night, risk-free trial. Complete your sleep system with our lightweight, hypoallergenic polyester down-alternative pillow. Designed to feel airy and cloud-like, it offers gentle, down-inspired support ideal for back and side sleepers and is available in both Standard and King sizes. Together, these Tuft & Needle essentials create a cool, clean, and comfortable sleep environment made for restorative rest night after night.
