Solo Diner is designed with both you and your child in mind. It is constructed of 100% high-density polyurethane foam for supreme comfort and lasting reliability, feeding after feeding. The unit is covered in a non-toxic, water resistant polyester fabric that wipes clean in seconds. The seat inserts and headrests that go next to your baby’s skin are made of 100% cotton, and secured by velcro for easy removal so you can toss them in the washing machine.
