Hit the road in endless comfort with the Memory Foam Lumbar Support Cushion from Goodyear! This cushion is made of the highest-grade memory foam available. The foam adjusts to hug the curvatures of your lower back to offer you long-lasting stress and tension relief without you needing to constantly reposition yourself or your cushion. This cushion is engineered with a contoured design that aligns strongly with the natural shapes, curvatures, and arches of the lower back. Its optimized structure enables it to achieve long-lasting stress and tension relief on even the bumpiest of rides. This is no ordinary rectangular cushion -- with this cushion, the shape is the secret. A back strap lets you use this cushion in pretty much any vehicle imaginable -- perhaps even a bus! -- because you can shorten or lengthen the strap at a moment's notice. Once this cushion is securely fashioned to a vehicle seat, it stays there. For road trips and daily commutes, rough roads and smooth streets, speedy journeys or slow travels, this cushion fits all. A removable cover with ventilated mesh keeps both you and your cushion dry and clean. The ventilated mesh wicks moisture away from your lower back, keeping you sweat-free as you sit squarely against your cushion for hours at a time. Hot air escapes and makes its way away from you. Remove the cover and include it in your next laundry run to keep your cushion looking new and clean, and simply return the cover to the foam once dry. It's never been this easy to clean your cushion and fend off pain during even the longest of car rides. ● Dimensions: 13. 5” x 14” x 4. 5”● High-grade memory foam retains shape and reacts to user's precise back shape● Contoured design achieves optimal alignment between user and cushion● Adjustable strap achieves easy cushion fit on most standard car seats● Ventilated mesh wicks moisture away from lower back during cushion use● Removable cover streamlines and optimizes cushion cleaning
