Review - Safety 1st S1 Rumi Air Harnessed Booster Car Seat ~ Style and Safety in One

Rate this post

Safety 1stPicking out a car seat was one of the most intimidating tasks I completed as a soon-to-be parent.  I can remember how daunting it was knowing that your brand new bundle of joy would be protected by the piece of equipment you selected and how you weren't allowed to leave the hospital with your baby without first having a car seat properly installed.

Once Riley outgrew her rear-facing car seat, we received a hand-me-down from a friend, but it didn't seem very comfortable and it definitely wasn't convenient or well-designed.  Safety 1st, a leader in quality children's safety products for over 25 years, allowed Riley and I to review the S1 Rumi Air Harnessed Booster Car Seat.  Keep reading to learn more!

I reviewed the S1 Rumi Air Harnessed Booster Car Seat from Safety 1st, which retails for $179.99, but is currently on sale for $162.98 with FREE SHIPPING.

Introducing the S1 Rümi™ Air Harnessed Booster by Safety 1st. The Rümi Air features Air Protect®Side Impact Technology and combines this with FlexTech™ – a state-of-the-art energy management design that offers additional protection.

Air Protect®, developed using the advanced Dorel/Kettering testing method to simulate real-life side impacts, provides greater energy absorption and head containment in the most severe impacts; where intrusion into the passenger compartment occurs. For customized safety, the easy-adjust 12-position headrest of the Rümi properly aligns the Air Protect system with the child’s head, where it’s needed most.

The unique internal design also allows for a higher harnessed weight range on the Rümi™, up to 65 pounds. Keeping your child secure in the internal harness system longer.  With convenience features like the no-rethread harness, single-hand adjust headrest and integrated cup and snack holders, this car seat boasts the best of both safety and style.

I was delighted at just how stylish and secure the S1 Rumi Air Harnessed Booster Car Seat was.  The padded headrest felt so luxurious and comfortable that I know my daughter will be using this to rest her head against when she happens to fall asleep in the car.  I'm thrilled to know that it will also protect her precious noggin in the event of a truly serious car crash, thanks to the Safety 1st Air Protect technology.

The harness belts haven't gotten twisted or tangled, which is always a plus, and getting Riley in and out of this car seat is a breeze.  I'm also pleasantly surprised at how well the S1 Rumi matches the interior fabric of our family car.  It's as if it were made specifically for our vehicle!  Riley of course was in love with the cup holder and small snack/toy tray located on the armrests of this car seat.  She felt so grown up having her own little compartments with which to store things while on the road.

Installing the S1 Rumi Air Harnessed Booster Car Seat couldn't have been any simpler either.  The time it took to remove it from its box, adjust it for Riley's height and install it in our car, was only about 15 minutes.  The one feature that left me feeling a little disappointed though was the length of the safety harness itself because I'm afraid Riley won't be able to wear it for much longer.  Even though she is only two and a half and weighs in at just 30 pounds, she has almost outgrown the harness.

I have the belts pulled out as far as they will go, but if she grows another inch or two, they will no longer be able to be used and I will need to convert this seat to the belt-positioned booster configuration.  It's not that this is a problem, I just thought that Riley would be wearing her harness for a lot longer, since the specs on this car seat stipulate that we shouldn't remove the harness until she reaches 40 pounds.  I guess that's what being in the 95th percentile for height will get you!  :wink:

We are extremely happy with the new Safety 1st S1 Rumi Air Harnessed Booster Car Seat, for it is the hallmark of innovative design, safety and style, all rolled into one!  If you are in the market for an extremely versatile car seat, which could easily be used for many years, then I highly recommend the Safety 1st S1 Rumi Air Harnessed Booster Car Seat.
