Make sure the back (where the baby places his/her back) of the seat is all the way upright. There is a cord on the back of the seat which you can adjust to move the seat to a fully upright position or down to a "sleeping" position. This will give you maximum space in which you can place items below. This is the only way... There is no way to lower the storage compartment - believe me, I've had the product for two years.
