The Dreamtime booster sounds like it may be a good alternative to the turbobooster after we see the crash data stuff, of course. It looks like it provides quite a bit more side impact protection than the turbobooster and the price is comparable. According to the website's specs the seat portion is 16.5 inches wide (only .5 inches wider than the turbo) and the high back portion 17 inches wide. I'm not interested in a seat that goes lower than the turbobooster, however. My oldest two children have met the height on the fisher price booster (18 inch torso) and therefore I sold it away because I am not ready for them to go backless yet.
The Baby armor seat that extends to 20 inches with eps foam sounds pretty good for $80. It still appears to have more sip than the turbobooster. According to the website it is 17 inches wide. I also do not care for the "Baby" Armor name. Although my children have no idea what names their car seats have, I know. Parents on craigslist often advertise booster seats as "toddler" seats. I know I don't consider a 6 year old to be a toddler. The average parent trying to save money on car seats will see this Baby armor is good for 30-110 pounds and believe they've found the last seat they need to buy for their 30 pound 1 year old. (Since many don't know car seats expire.) The boosters need an age minimum of at least age 3, but age 4 would be optimal. I understand having a booster for the 32 pound 7 year old, so if the seat is good for a 30 pound kid, the age minimum would suffice.
I want to see the Baby Armor when it comes out, but I think the Recaro Vivo sounds like a better seat for the money since it extends taller (21 inch torso) and has nice, deep sidewings. It is priced at around $70 right now. I can afford a $20 backless when the time comes for my kids to go backless.
