Special Tomato MPS, Large

A forward-facing-only car seat made by Bergeron Health Care, based in Dolgeville, NY.


This car seat has much higher child weight and height limits than conventional models.  Its rigid shell is customizable to meet a child’s needs by choosing among various sizes, contours, and colors for cushioned headrest, body, and seat pads. While the foundation is a durable structural foam with an internal frame, the headrest, back, and seat cushions are made of latex-free material that is soft and malleable yet durable (withstanding deflating, cracking, and impermeable to fluids).

The contoured seat cushion pivots 30 degrees to adjust the seat-to-back angle for proper alignment of the child’s pelvis. The head and back cushion can be adjusted for child growth and  swapped out for larger sizes, when needed (sizing options shown below).  Adjustments can be made to the seat cushion to provide a range of positions between 15 degrees of hip flexion and 15 degrees of hip extension without reclining the seat back. The seat cushion has a built-in medial knee support.
