DPIST&reg; Home Premium Memory Foam Car Lumbar Cushion & Car Neck Pillow Kit [Black ] Material: High Quality Malleable Memory foam Machine-washable & removable breathable mesh cover. SPECIAL NOTE: There is no elastic strap on back side of Lovehome car lumbar support as the strap will most likely impede the proper deployment of the seat's airbag if any accident. (We would highly recommend you to remove or not to use the strap to mount the lumbar support on your car seat for safety considerations if you are currently using one like that.) Package includes: 1 x lumbar cushion, 1 x neck pillow
