Was pleased with the car seat I bought from Kidsy. It was in the condition they described and arrived quickly. Thank you!

Reddit Insights

5 threads · r/moderatelygranolamoms, r/BabyBumpsCanada, r/Buyingforbaby, r/beyondthebump

Reddit users predominantly praise the Chicco Keyfit series for its safety, ease of use, and stroller compatibility, though some note it can be heavy and may require careful adjustment to avoid positioning issues.

The majority of users express satisfaction with the seat's safety, ease of use, and compatibility, while a few note issues with weight, fit adjustments, and early outgrowing.

Use Cases

  • Infant car seat for daily travel and errands
  • Travel system with compatible Chicco strollers
  • Using adapters with non-Chicco strollers (e.g., Uppababy)
  • Carried into the house during cold weather or left in car while babywearing

Watch Out For

mediumNewborn insert must be removed after 11 lbs to avoid improper harness fit and chin-to-chest risk.
lowSeat can feel heavy, especially as baby grows, compared to premium lightweights.
lowMay be outgrown by height before reaching weight limit, particularly for taller babies.
mediumRequires proper recline angle in vehicle; angle is different on flat surfaces (e.g., floor), leading to confusion.
lowStraps may need adjustment to avoid cutting into the neck when the baby is small.

Community Q&A

What is the difference between Keyfit 30 and 35?
The 35 has higher weight/height limits, a no-rethread harness, and a load leg; both are safe, but most children outgrow by height before weight. The 35 offers easier harness adjustment.
Does the Keyfit cause chin-to-chest (C-shape) positioning?
It is uncommon but can happen if the seat is not installed at the correct angle or if the newborn insert is still used after 11 lbs. Check with a CPST and remove insert when appropriate.
Can the Keyfit be used with an Uppababy stroller?
Yes, with a separate adapter (available for Vista and Cruz). The combo works well but the adapter must be on hand when folding the stroller.
How do I clean the fabric?
The fabric is fully removable and machine washable.

Compared To

vs Uppababy Mesa

Most users prefer Chicco over Mesa for better value and safety ratings, though Mesa is lighter. The Keyfit requires an adapter for Uppababy strollers.

vs Clek Liing

Liing is mentioned as a lighter, easier-to-install alternative with narrow width, but Chicco is more affordable and widely loved.

vs Nuna Pipa

Nuna is suggested as a premium alternative if Chicco fit issues persist; noted for its load leg and easy installation.

  • Advice on adjusting fabric, straps, and angle for Chicco Keyfit

    All of the fabric came off on ours. Check the manual for which insert pieces are appropriate based on weight. And double check that the straps come out of the seat either right at or just below shoulder height. Also when you say her chin is too close to her chest, are you assessing this when the car seat is like sitting on the floor/ground or in the car? The base holds the seat at a more reclined angle when kiddo is in the car (or stroller)

  • CPST comparison of Keyfit 30 vs 35

    Both the Keyfit (30 and 35) and the Liing are tech recommended seats as they are both fairly compact (so fit well in most vehicles), easy to use, and not outgrown quickly. The Keyfit 30 has lower limits, 30lb/30” but most kids tend to outgrow their infant seat by the third maximum which is the fit requirement. You must be able to maintain 1” of clearance above their head inside the car seat shell. For the 35, the limits are higher at 35lb/32” but you must maintain the 1” clearance above their head on the headrest.

  • Positive experience using Chicco Keyfit 35 with Uppababy stroller

    I have an UP Cruz V2, love it so much and we used a Chicco Keyfit 35 with it (you need the adapter) Loved it and would use it that way again! You only use the infant bucket for so long, then need a convertible seat anyway. So IMO it made more sense. Plus the Chicco has excellent crash safety ratings. My baby grew out of the infant seat when he was shy of 6 months since he’s big lol but the seat isn’t too heavy, I felt like it was totally manageable. ETA we really just keep our stroller in the car, so the adapter was always with it or near it. We also purchased the infant snug seat for the stroller and used that if we didn’t feel like lugging around the car seat, it came in handy for sure!

  • Positive review highlighting ease of use but quick outgrow for large babies

    I love how easy and lightweight it is, but I have a huge baby and she's going to outgrow it quickly. The simple click in/out for carseat and stroller is a dream when I'm in a rush, and the straps are so easy to tighten/loosen to get her in and out without having a fit.

  • Comparison to Uppababy and recommendation to check install for C-shape issue

    We have a UB Cruz V3 and were gifted a used Aria from a friend but after a lot of deep reviews we decided to go with the Chicco Keyfit 30 as UB are having a lot of issues with C shape and chin to chest with their car seats. This is one of the first times I’ve ever heard of the Keyfit 30 causing c shape issues so I would definitely recommend having the install double checked as it is usually one of the higher rated car seats with independent testers and CPST’s. Some car seats work well for some babies and not others. If not the Chicco the Nuna would be my best recommendation. From all the reviews I saw it is also a great option, or the Clek Liing.
