Great design!
Love love love the stability bar and the click tight feature to the base! I feel that is something you see with more of the luxury brands. The fabric overall seems cushy but not bulky. Previously I had Chico key fit with their upgraded fabric sold on website. This fabric seems thinner but not in a bad way. Canopy is stretchy and seems breathable. Seat itself seems bigger than key fit but maybe slightly lighter? Takes a little push to click it in to the base but no biggie. Also I am SO HAPPY that the adapter connection area is the same as maxi cosi Nuna etc. so it works with the stroller I want haha
A just have I always have loved britax car seats 😍😍
I loved it we got this car seat because I always have loved britax products This is an amazing rear, facing only car seat. The quality of this product is far superior to any product I have experienced in the past when it comes to car seats. All the levers and buttons are of nice material and precision. It has levelers on each side. The cloth is also really nice and seems very washable. And the base is very sturdy and really makes it a cinch clicking this car seat in and out of the car. There are no watch out or gotcha‘s on this one. It really works. Just plug and play and it’s really nice. I highly recommend. This is a really cute car seat. It has an adorable newborn insert that helps the baby fit snugly inside. It has an unfolding top which is great for sunshade and rain. There is an instruction guide and a base and a rebound reducer that it comes with. It is not lite but feels very durable and sturdy. It's great quality. The material is excellent and feels very soft as well. I would highly recommend this. Can't wait to get out baby into this when she is born When you have a new baby , you have to take care to get the right seat. You need one that's easy to take in and out of the car. This seat is easy to maneuver, install, and the base fits securely. The cover has a sun protection, which is great for sunny days. It has several points on the harness and is easily adjustable for a good fit. This works with a stroller of the same brand, which is also convenient, if you want to buy it. It snaps right in. I like this a lot. And they never disappoint britax products are the best
Obsessed! Easy to Use!
This carrier is very good looking, is high quality, and the base makes getting the carseat into the car a breeze! The base has a smart click technology, so all you have to do is set the car seat on the base and it'll click itself into place. Love the stability bar too!

Reddit Insights
5 threads · r/BabyBumps, r/CPST, r/parentsofmultiplesReddit users find the Britax Willow S a safe and reasonably priced infant car seat with easy ClickTight installation, though some are concerned about the normal seat movement and limited stroller compatibility.
Overall, the seat is well-regarded for safety and ease of installation, but the seat wiggle (though normal) causes concern, and the lack of adapters for non-Britax strollers is a notable drawback.

Community Q&A
- Is the seat supposed to move/wiggle on the base?
- Yes, a small amount of movement is normal as long as it's securely latched and the base doesn't move more than 1 inch.
- Can you use LATCH in the center with latch borrowing?
- The manual does not state latch borrowing is allowed; using the seatbelt with ClickTight is easy and recommended for center install.
- Does the Willow S work with older Britax adapters or non-Britax strollers?
- No, it is a new generation seat and currently has no cross-compatible adapters for non-Britax strollers.

Comment explaining ClickTight makes seatbelt install easy for center
Your seat is specifically designed to make a seatbelt install easy, that’s what ClickTight does. I would install it with seatbelt if you want it in center.

Comment attesting to loving the seat and normal movement
we’ve been using this seat since bringing our son home in December and I’ve loved it! Ours did wiggle in the base but we wound up going to a fire station near our home to confirm we’d installed it correctly and they said it was normal.

Comment noting limited stroller compatibility for new Willow S
The Willow S is part of Britax’s new generation of car seats. Unfortunately it does NOT work with the adapters for previous generation Britax seats (ie B-Safe 35 line and B-Safe Gen 2 line). With the redesign of stroller compatibility and completely new line of seats being brand new to the market, there are no cross-compatible adapters that I’m aware of to make the new Britax seats compatible with any non-Britax strollers at this time.

Comment confirming seat movement normal per manufacturer
We called and they said it sounded normal. But they confirmed when we left the hospital that it was normal. They said as long as your hear the latch and it cannot be lifted out, it was safe!
