  • Best seat ever . Must read
Style: Tranzitions Pattern Name: Booster Seat Color: Black
We've been through many seats this is my favorite to DATE . My 4yo and 3yo use these for reference . They are machine washable and come with a "butt pad" that is easy to remove perfect for any accidents spills or if someone pukes (ask me how I know lol) They are easy to adjust the straps to my kids can use either seat and with one hand and 3 seconds they are safely adjusted to their size. The cup holders are great as they sit lower with my kids like . And with there being no real barriers on the seat the kids have more "leg spreading" room . They also really love the shoulder pads (no more lines on their necks or shoulders) These are also lighter than your typical seat . I can carry easily with one in each hand to transfer cars (I'm 5' for reference) . It s also so easy to get a good install on them . Trust me I was skeptical with he price being under 100 at the time but I can confidently say that if offer this seat or a 500 dino ect for free I would choose this one 10x out of 10 . ... show more

  • 4.5 stars!
Style: Tranzitions Pattern Name: Booster Seat Color: Black
This is a great product and still going strong after 2 years! It’s easy to clean too. Remove the paddings throw in the washer and hang dry. Wipe everything else down. Took a picture of everything the first time I cleaned it so I would know how to set it back up. Sometimes the straps would get twisted which was annoying a bit. Overall though this is great! ... show more

  • Definitely Happy Customer
Style: Tranzitions Pattern Name: Booster Seat Color: Black
I was going back and forth between 3 different ones and decided to skip the cheaper ones for this one, mainly because the others said they were flimsy. This was totally worth the extra $50. Its not bulky, its sleek color, great size and still feels extremely sturdy while being light weight. Love that for that little extra as well my child has a car seat up through their youth as well. Easy assemble and install. Comfortable with extra padding pad. A little iffy on the cup holders but we shall see. ... show more
