The new BRITAX PINNACLE 90 Combination Harness-2-Booster boasts the ground-breaking CLICKTIGHT Installation System combined with BRITAX's leading Head Safety technologies. The PINNACLE 90 keeps your growing toddler safe and offers parents the peace of mind of a secure and easy car seat installation each and every time. CLICKTIGHT Installation System is an innovative technology that allows parents to easily achieve a safe and secure installation using a vehicle seat belt every time throughout the life of the seat without having to worry about the weight of the child. The PINNACLE 90 offers a forward-facing, five-point harnessed weight capacity up to 90 pounds, with an industry-leading 20.5 inch shoulder harness height. The PINNACLE 90 also converts to a vehicle belt-positioning booster seat that can be used up to 120 pounds. PINNACLE 90 incorporates BRITAX's leading Head Safety technologies to protect your child during a crash by minimizing the forward movement of your child's head during a frontal impact. Head Safety technologies include: Base with SafeCell Technology , Integrated Steel Bars, and Energy Absorbing Versa-Tether . The PINNACLE 90 is also equipped with energy-managing Side Impact Cushion Technology, reducing side impact crash energy by diverting crash forces before reaching your child and incorporates BRITAX True Side Impact Protection for three layers of side impact protection. True Side Impact Protection provides an extra layer of energy-absorbing EPP foam that contains your child's head, neck and body, keeping them in true or aligned, during a crash. May not be compatible with all vehicles. See user guide.

Britax Pinnacle 90 Combination Harness Booster Seat


Britax pinnacle

 from Chesapeake, VA– Verified Buyer

I love how easy this seat is to install, especially since latch is no longer an option over 40lbs. Roomy, adjustable overalls great booster. I also love how the harness can be removed. My dd also loves the cup holders

 from Front Royal, VA– Verified Buyer

I owned a Britax Boulevard until my son outgrew it. I chose another Britax model after my son walked away completely unharmed from a bad car accident the previous year (he was riding in the Boulevard at the time) The Pinnacle 90 was easy to install, easy to adjust and my son feels like a king in it!!

Great car seat and best price

 from Arlington Heights, IL– Verified Buyer

We needed to get a new car seat for our 4 yr. old and wanted to stay in the Britax line. This car seat was exactly what we were looking for and it was at the best price across options. We received it very quickly and the item packaging was in perfect condition. This is the 2nd Britax car seat we have purchased and have been very happy with this car seat and with each of our purchase experiences with Wayfair. (This is approx. our 8th purchase.)

Good as a seat, not great for everyone as a booster

 from Texas– Verified Buyer– Top 1000 Reviewer

I love the high harness height on this seat, but this seat is a BEAST and made me lose my ability to fit 3 car seats or people in my SUV. The added side airbags make it even larger than the Frontier 90. The click tight install is SO nice and makes it super easy to install. I converted this seat to a booster for my child that is 6 years old, 48 tall and 43lbs. The booster fit is not great and that is what the IHS also found. This seat failed booster fit 50 of the time....meaning that it could be deadly as a booster if the fit is not right. I am also not crazy about the way the harness tucks away for booster mode. You essentially shoved all the loose harness straps into the fabric cover of the side wings.

I did receive this booster seat. I have not yet had a chance to instal it because it is a gift but I have overlooked it and it looks great.

Booster Seat

 from Washington

Everything with this booster seat was just what I was expecting. It is good quality, the color and size match the description, and it's nice and sturdy.

Was this helpful? Yes / No

Secure fit!

 from CYPRESS, TX– Verified Buyer

It's a pain to install, as all new car seats are at first, and the harness release button is hard to get to but I love this combo booster. It connects (we use LATCH) and feels very secure and tight fit, as well as the harness is a tight fit. Seems very safe!
