Spectrum Belt-Positioning Booster Car Seat (Bubbly Blue) is rated 4.4 out of 5 by 21.
Rated 5 out of 5 by from Great Booster Seat I received the 2 in 1 Spectrum Belt-positioning booster car seat about three weeks ago. It was super easy to assemble. I'm impressed with the safety technology the LYF +Guard Advanced Compression Technology system gives me peace of mind knowing that my grand children will have extra protection in case there ever is an accident. The height adjustable back rest is great because I have three grand children ages 13 months 3 and 4 years old. The wide comfortable seat is a plus. My grand children love the two side storage cups for holding snacks and a drinking cup. The best advantage is that they love that fact that they can see very well out the car window.

Rated 5 out of 5 by from I bought this carseat after spending a few 100 of $ for both my children. They refused to use those car seats and one day I came across this Evenflo Spectrum Carseat. They loved it! They are spacious and comfortable when they fall asleep. Keeps their heads and body at great position as they sleep. Unlike the originals I first bought they're bodies would hang off to the sides not at all safe. I'm even saving to purchase two more and have their father have this carseat in his car to keep our children safe. I have a few friends that are expecting and tell them to get this specific carseat. Recommend it for any child especially if your child is big and tall . My children are taller than most kids their age.

Rated 4 out of 5 by from Easy and effortless The booster arrived in a small box, this kind of confused me because I was expecting a big car seat box that takes up my entire front porch, but the package arrived in a slick box with three large sections of the seat nestled inside. The seat was very easy to assemble; clicking the head section, back section, and bottom section together in a flash. It’s pretty lightweight compared to my son’s old booster seat. My son is seven years old and pretty tall, but this seat extends to meet his height and then some. When I asked my son his thoughts he said “I really like it.” Also, I will note that while driving with it empty it does not make any rattle noises. My only complaint is that the head piece is pretty bulky.

Rated 1 out of 5 by from Car seat guide prevents seat belt from retracting. The car seat guide holds the seatbelt in a way that doesn't allow the belt to retract.

Rated 5 out of 5 by from LOVE THIS! I got this seat little over a month ago and I am still in love it with. I love how it's easy to move from car to car. My child loves that he can sit comfortable in it and see out the window good. I love how the headrest has sides that come out round more, makes me feel like it will help protect him more if something was to happen. It is very easy to clean a dirty spot on it. Doesn't take up a lot of space like some I have seen do. Love the little drawer space on the side. It's just enough room to store some of his favorite toys and not have to worry about transferring them to another car. Love the color of it since it can be used for a boy and girl. I have had many products that are evenflo and they are never let me down. Love Love Love this seat.

Rated 5 out of 5 by from Love! I absolutely love this booster seat! It was easy to put together and seems very secure and comfortable for my little one. I love that it is height adjustable, my three year old is on the tall side and has been taller than the last two seats she’s had. I also like that it has a clip for the seatbelt to help hold it in the proper place both for safety and ease of use. She also keeps telling me how much she loves her new seat compared to her last one she complained about almost every time we went somewhere.
