LA Baby’s tradition of high quality yet affordable innerspring mattresses continues with our Health Care grade line. Flex Edge Clips provide extra side edge support and safety when baby starts to pull themselves up to a standing position or when the mattress is used with a toddler bed. A firm comfort layer on infant side cradles and supports your baby’s developing spine, and the CertiPUR-US certified convoluted foam on the toddler side gives more comfort so your toddler can restfully sleep. Proudly made in the U.S.A. from domestic and imported sources. 260 Heavy Duty 15.5 Gauge Steel Coils for Maximum Durability. 9 Gauge Border Rod for extra strength and support. (The lower the gauge the thicker the steel.) Flex-edge clips for the ultimate in side edge support and safety. Cotton-poly coil wrap prevents loss of cushioning material. Two layers of Ortho-Insulator pad for additional durability. CertiPUR-US certified Convoluted foam for the best in toddler’s comfort while blended cotton on both sides provides support to baby's developing spine and a restful nights sleep at any age. Anti-bacterial, water and tear resistant triple laminate cover. Air-vents promote a fresh mattress. Cloth binding is sewn with a lock stitch that helps prevent edge seam from splitting and moisture from entering.
