A few months ago I got to sit down with one of the founders of Clek. It was an interesting story. They launched from within Magna, an automotive company. But somehow the established brand didn't hamstring the creativity of the Clek designers.
In 2007 Clek delivered Olli--a booster seat that excels at both safety and kid appeal. I had Clek ship me a sample to check out. As soon as I unwrapped the package my girls were clambering onto the Olli Paul Frank Julius Booster Seat ($99). Sure the red monkey is adorable, but the seat is also darn comfy. I sat in it myself. There is something about the slightly rounded arm rests that feels so good. And they have designed the seat with extra padding to avoid the "numb-bum" syndrome--you know when your back side loses sensation.
Right now my girls are too young for this seat (most states require kids to be AT LEAST 40 lbs and 40"), but I did get to try it out on an older child. First, let me say this seat is a pleasure to install. It is light and has a carry strap (ideal for travel). It uses the LATCH system which in place in most cars and is a breeze to set in place. You can click this page to see a little video (about half way down the page). You know you've got the seat in place correctly when you hear the "click" or "clek" sound (that is where the name comes from).
Yes, I know the seat costs more than others. But if it has kid appeal and makes them WANT to ride safely plus makes it easy on parents to install I say it is worth the investment. Remember the NHTSA reports children ages 4 to 8 who use booster seats are 59% less likely to be injured in a car crash than children who are restrained by safety belts alone. Pick from eight colors and Paul Frank patterns. Most can be found on Amazon.
