## Description

The Crosstown Slim All-in-One Convertible Car Seat is made to be with you for years, comfortably fitting your little one from birth to 10 years with 3 modes of use: rear-facing (5–40 lbs., 19"–40"), forward-facing harness (30–65 lbs., 34.4"–49"), and belt-positioning booster (40–100 lbs., 43.4"–52"). Its ultra-slim 17" design is a space-saver you’ll welcome as it allows for 3 across the back seat of most cars. The 1-hand adjustable harness and 8-position headrest ensure the proper fit and keep your little one comfy, all without the need to rethread the harness during adjustments.

Review: Baby seat - This baby seat has been an excellent purchase. The installation was very simple thanks to the clear instructions and the anchoring system, which remained firm from the first attempt. The quality of the materials and the feeling of security it offers give me a lot of peace of mind. My baby travels comfortably, the padding is soft and breathable, and the harness fits well without hurting. In addition, I liked that the seat has several reclining positions, which allows the baby to go more relaxed on long journeys. Another point in favor is that the cover can be easily removed to wash it, something very practical with small children. In short, a safe, comfortable product with very good value for money. I totally recommend it to parents who seek tranquility and comfort on every trip.
Review: Affordable, Easy to Set up/Adjust, Quality - First time car seat owner. I bought it so I can pick up my little niece from daycare. Setup was easy, seemingly comfortable, good quality, and easy to adjust for the baby's growth. My sister (her mother) has an expensive car seat which is not nearly as easy to adjust for growth. This one should be good for infants up through little kids. Baby loves the cupholders. Great deal!
