Unlike lesser foam pillows that create a stifling, overheated feeling, this is the pillow that uses an exclusive perforation pattern throughout its foam core for maximum air flow. Despite its cotton-like breathability, the latex foam conforms to the contours of the head and neck, keeping the spine comfortably positioned, while its naturally antimicrobial properties eliminate the build-up of common allergens such as mold and dust mites. The pillow's machine-washable wool and terry cotton cover provides a second layer of breathable comfort, trapping an insulating layer of dry, temperate air next to the skin, creating a micro-climate that helps eliminate temperature fluctuations. The cov er's wool also efficiently absorbs moisture and dissipates it back into the air. Queen Size: 7" H x 29" W x 171/2" D. (4 lbs.)
