5.0 out of 5 stars My favorite carseat, January 9, 2008

This review is from: Cosco Alpha Omega Elite Bouncing Sheep 3-in-1 Booster Seat (Baby Product)

I would have to disagree with the other review. I own 2 of these and purchased 2 more for the grandparents. The review on consumer reports are GREAT so when we went out to get a toddler carseat we bought one of these, and a Evenflo triumph (also highly rated)(one for each of our cars). I HATE THE TRIUMPH. My son complains his butt hurts. The straps suck. The Alpha Omega is wonderful. It fits in my car as tight as possible. It does not wobble a bit. My husband isnt even able to get it to wobble after we anchor it in. Its very comfortable and my son never complains about his butt hurting. I have since bought another for use for daycare as well as two others for grandparents. The straps tighten easily for us and do not loosen. Its very easy to install if you know anyting about carseats. Theres 2 anchor straps with hooks that hook right into your cars anchor system. As well as one that goes up the back seat to secure the upper portion of the carseat. I recommend it to everyone.

2.0 out of 5 stars Installation and use do not make you feel safe, January 8, 2008

This review is from: Cosco Alpha Omega Elite Bouncing Sheep 3-in-1 Booster Seat (Baby Product)

I purchased this after analyzing safety reviews on the Natl Highway Safety site and this looked like a good option based on paper. We've been using this for almost 2 years in grandparents' car; they are my daughter's caregivers on weekdays. This review is partially based on our experience using the Britax Roundabout installed in our car.

Seat is difficult to install CORRECTLY. Definitely not an easy in/out. (Roundabout is fantastic. Multiple positive experiences to take on airplane, install in rental cars). My husband had to refer to the manual in depth. My father who is a very intuitive and capable man has popped this in and out and he insisted it was properly installed. However, it always wobbles side to side. Sure enough, when my husband checked, it was done incorrectl. Bottom line: its poor design is conducive to user error.


Hard to use safely. The straps were difficult to tighten. I have asked my parents many times to make sure straps are snug but they are difficult to pull and they seem to loosen.

If you're shopping for something that is more than an occasional use especially in someone else's car (you'll have less control over it to ensure it's correctly installed and used), it is worth the extra premium to get a significantly easier to use seat. You'll worry less and your child will truly be safer. Recently, I was rear-ended in our car which had the Roundabout. While not a catastrophic accident, it certainly makes us rethink whether the extra premium was worth in grandparents' car when we buy one for our 2nd child

4.0 out of 5 stars pricey for its quality overall, yet very ergonomically agreeable, September 2, 2008

though it has shape good to allow ergonomical fit or snugginess around the child, it does come w/ a harness that is average, if not a tad unfriendly. Quality at first glance is more than any lesser brand w/ a similar price tag. You would expect more sturdiness in the material at this level called "Elite"; but it'd slightly disappoint you, the build quality is rather barely above standard. I rate it 4 stars for its ergonomics and hollow seat that caves in, whereas other brand do not have this. I would recommend it to all nevertheless, albeit its price and disappointing build quality.
