Fisher Price Futura 20/60

Hi,

I just saw a new toddler/booster seat at Toys R Us
called the FP Futura 20/60. It is forward-facing
only for children 20-60 lbs and has a tray with
a cup holder, but the interesting thing about it
is that it uses a harness all the way to 60 lbs.
All of the other boosters that I have seen are
simply belt-positioning boosters--you have to
stop using the harness once the child reaches
40 lbs.

Does anyone own or know anything about this seat?
My son will be 3 in August, but he's been over
40 lbs since May. It would be great if we could
use a booster with a harness, because he can
wriggle much more in his belt-positioning booster.
It just doesn't seem very safe. But I hate to buy
a brand-new product without knowing anything about it.

Thanks,
K
