Colgate’s Eco Spring Ultra II is an innovative, eco-friendlier crib mattress designed with your littlest one in mind. This firm mattress is made with the highest quality, sustainable component materials, including renewable coir fiber from coconut shell husks, natural cotton cushioning layers, and eco-friendlier foam made with sustainable plant oils. Colgate believes it’s what’s on the inside that counts, which is why the Eco Spring Ultra II boasts an exceptionally high quality spring unit made of 150 coils of extra thick 13.5-gauge tempered steel and 9.0-gauge border rods for extra support. This is all wrapped in a waterproof damask cloth cover, which is closest to your baby’s skin. Like all Colgate mattresses, the Colgate Eco Spring Ultra II is GREENGUARD ® Gold certified, CertiPUR-US ® certified, CPSIA certified, and compliant with all federal and state flammability requirements – without the use of fire retardant chemicals. Your Eco Spring Ultra II is proudly handcrafted in the USA by Colgate, The Crib Mattress Specialist®, a family-owned and operated business. Keeping dreams safe since 1955.
