Questions?

Is the frame steel? What is the depth of the seat where the child sits? What is the expiration date?

There are reinforced aluminum tubing around the sides. The rest of the seat is engineered plastic. Think EPP foams surrounds the child. The seat depth is approximately 17″. Expirations is 8 years.

Is this car seat fully washable?

The cover is machine washable.

Does this have a rigid latch system?

This has soft LATCH connectors. The connectors help keep the seat in place when it is unoccupied. Otherwise the seat belt is what restrains the child in the car seat
