The infant Cushie Tushie was developed and patented by Pediatric Neurosurgeon, Dr. Monica Wehby with the comfort of the infant in mind. Infants are tightly strapped into their car seat and unable to move freely. Most car seats are made with hard plastic and very thin padding which can cause pressure on the backs and bottoms of infants. The infant Cushie Tushie is designed with gel polymer and memory foam to add extra cushion and alleviate pressure on the backs and bottoms of infants providing a more comfortable experience while strapped into their car seat. Uncomfortable infants are fussy infants and the goal of the infant Cushie Tushie is to provide maximum comfort, so infants are less fussy and more comfortable while strapped into their car seat. Features: Enhances infant comfort Reduces pressure points Designed for long-term durability and heavy use, great for extended sitting Interior gel matches body consistency, providing superior body-conforming comfort Odor free Skin safe - latex and plasticizer free Waterproof, stain/spill proof and fire retardant Gel pad can be washed in mild detergent soap solution followed by a rinse and pat dry Soft, zip off covers with nonskid backing are easily changeable and machine washable Designed to fit all infant car seats
