Leading the market with unparalleled full-body impact protection, the Optyma features a deep, supportive head and body structure with a no-torque backrest. The energy-absorbing structure and high-density foam work together to absorb and disperse energy in the event of a crash. Outboard Side Impact Protection safeguards your child and other passengers in side-impact collisions, while purposefully designed belt-path routing ensures that the shoulder belt stays in place and the lap belt is positioned low on your child’s hips to prevent submarining.
For added convenience, the Optyma includes a 1-touch, 7-position headrest height adjuster and premium comfort foams that keep your child comfortable on every ride. The removable, machine-washable seat pad handles unexpected messes, and the interchangeable cup holder keeps snacks and toys within easy reach for your little traveler.
At Harmony Juvenile Products, we’re a family committed to providing safe, comfortable, and affordable products to help you travel with peace of mind, knowing your family is well protected.
