The Britax Pioneer 70 Combination Harness-2-Booster Seat offers premium safety, comfort and convenience for your growing child that is ready to graduate from their convertible car seat.The PIONEER 70 incorporates BRITAX's leading safety innovations, including their patented Head-Safety technologies such as: Base with SafeCell Technology, Integrated Steel Bars, and Energy Absorbing Versa-Tethe. These components work together to protect your child's head by minimizing forward movement during a frontal impact. The PIONEER 70 also protects your child during side impact crashes thanks to its True Side Impaction Protection. This level of side impact protection incorporates deep side walls and a head restraint lined with EPS foam to shield and divert crash forces away from your child while keeping the head, neck and body aligned or ''in true.'' The Tangle-Free, Five-Point Harness contains your child and distributes crash forces across the strongest parts of the body.

Britax Pioneer 70 Harness 2 Booster Seat


Comfortable and safe

 from sewickley, PA– Verified Buyer

My daughter loves this seat! She was too small for her Britax Marathon, but too small for a no-back booster. She loves this one, and I especially like how safe it is, since she can't open the harness on her own while I'm driving!

Just as I had hoped. Easy install and has great cup holders!
