Our Verdict

The Britax Willow S is an impressive budget-friendly seat with much to offer. It earned one of the best crash test analysis results in the group, with sensor data that was low (low is better)for both the head and chest sensors. It was easy to install using the ClickTight method and without the base, and it is easy to use. The Willow is an attractive seat with good padding and a durable design. It is also relatively lightweight at under 9.7 lbs, making it a potential choice for travel or for those who plan to carry it without a stroller. This seat has a rethread harness shoulder height adjustment we don' love. WHile it isn't hard to perform, we worry that the need to take the baby out of the carrier and the carrier out of the car to make the adjustment might result in little ones wearing a poorly fitted harness. That aside, we think that it is a reasonably priced seat with much to offer overall and in its price range.
REASONS TO BUY
Better crash test analysis
Easy to install w/out the base

Performance Comparison

Crash Testing


The Willow S earned one of the best crash test analysis results with combined sensor data for both HIC (head sensor) and chest clip, which was better than most competitors.


The Willow is one of the few seats with low recorded G forces for both the HIC and chest clip sensors. The HIC, or head sensor, result is one of the best in the group, with only a few seats performing better with lower recorded forces (lower is better).

The Willow had better-than-average HIC sensor results in our crash tests.

The chest clip sensor shows similar results, with few being able to match the lower readings. Together, the combined results resulted in an impressive overall analysis score. Compared to the competition, the Willow S test results indicate it offers an additional margin of protection over the average seat in our tests.

We assume all of the seats in our tests have passed the federal guidelines and are safe. We run a slightly faster test on a sled seat that better mimics a modern car intentionally to help weed out those seats that offer higher performance than the average seat.

Ease of Installation LATCH


Only a handful of infant car seats were easier to install using LATCH than the Willow S. It earned an above-average score here, but it is important to note that at least one competitor earned a very low score, pulling down the average for the group.


The push-style LATCH connectors are easy to attach to the vehicle anchors.
Credit: Matt Lighthart

The LATCH connectors are push-style connectors, and the strap connecting them uses the same ClickTight lock-off as the belt installation. The base has a center pocket where the connectors store when unused, and the strap pulls across the lock-off when not tucked away.

The LATCH connector strap also must be threaded behind the ClickTight mechanism.
Credit: Matt Lighthart

The LATCH strap is narrower than a vehicle belt, so we had less difficulty sliding it under the mechanism and pushing the ClickTight closed. Once pressed closed, the base feels very secure and stable.

Recline Adjustment


The Willow S has a 4-stage recline adjustment that is adjusted using a push button on the end of the base closest to the ati-rebound bar. While this design is better than those that put the lever between the vehicle cushion and the base, it is still impossible to adjust with the carrier in place. There is a dial on both sides to check the installation angle.

While the ClickTight system secures the base to the belt, it requires some pressure and strength to do so.
Credit: Matt Lighthart

Ease of Installation - Belt


In our opinion, installing the Willow S with the vehicle belt is the hardest installation method. However, it is still average compared to the group and wasn't particularly challenging; it was just not as straightforward as some competitors.

While we like the ClickTight process on the convertible car seats, the ClickTight variation on the infant base is harder to use.

The vehicle belt and the LATCH connectors follow the same belt pathway on the Willow.

The design doesn't give much room to slide the belt under it, and there is limited visibility of what is happening under the lock mechanism.

Credit: Matt Lighthart

The lock-off is effective at locking the seat to the belt, but the design limits the leverage you can use to tighten the strap. The depression the lock-off pushes into isn't very deep, and we ended up smashing our fingers a little to use it. We can see this might be challenging for those with larger hands or fingers.

Aside from using the ClickTight lock-off, the rest of the installation is straightforward and quick. The base feels stable, but the seat rocks slightly.

Ease of Installation - w/o the Base


The easiest installation method for this seat is to install the Willow S without the base. It earned an above-average score for this metric.


The Willow allows for carrier installation without the base using either the American or European belt path method. The American path pulls the vehicle belt across the foot portion of the carrier through a designated pathway using only the lap portion of the belt.

The belt path on the Britax carrier pulls the lap portion fo the vehicle belt across the mid-section and the shoulder strap across the back of the shell.

The European method extends the shoulder strap around the back side of the carrier and threads it through a designated clip to hold it in place.

The belt path is color-coded with a thin blue line, and it is easy to access and use without the fabric getting in the way. Wrapping the belt around the carrier is also easy, and we didn't have any trouble with the canopy causing any trouble. The hardest part is getting the vehicle belt tight, but it feels stable once you do.

Ease of Use


The Willow S is an easy seat to use, earning an above-average score for this metric. We do wish it had certain easier-to-use features like a non-rethread harness assembly, but for the price, the rethreading feels acceptable.

Buckle


The buckle button on the Willow is square and somewhat recessed, making it harder to press if you have longer nails. It doesn't require significant effort, however, and is generally average and similar to other buckles in the lineup.

The chest clip is also relatively straightforward and requires two hands. It has a center-placed button connected to the left side of the clip, making it easier to slide the clip open with the right hand than the left.

Harness Tightening/Loosening


The Willow offers the standard fare for strap tightening and button release near the foot of the carrier. The strap is easy to pull with no resistance on the strap. The release button is easy to reach and use, but we pinched our finger when we put it in too far.

Harness Adjustment


The harness adjustment is a rethread operation that is pretty easy to use. There are four height options, and it requires removing the straps from a splitter plate, changing the level by threading the strap through a different slot, and reattaching them. You need to do it outside of the car with the seat empty. While it is not hard, it might get skipped if you are in a hurry. You must make the adjustment as soon as you realize a need.

Carrier to Base Connection


The carrier is easy to connect to the base. We recommend giving it a good tug after hearing the click to ensure it is properly connected. During testing, we did not have difficulty getting a good connection every time.

The carrier release lever is on the back of the carrier and can be used in conjunction with the carry handle to lift the carrier off of the base.

Handle


The handle rotates on a pivot point on either side of the carrier. Each side has a palm-side pressure button that you press simultaneously to turn. The canopy and the handle do not collide, and each will move independently. The sides of the handle somewhat rub the canopy sides, but it doesn't cause the canopy to move. There is enough space for your hand to grip the handle with the canopy open. The handle has three possible positions, and the manual says you can use it in the car in any position, but they recommend the “ReboundReduce” position, which is the same as the carry position.

Canopy


The Willow's canopy is small. It is easy to pull out and has a pop-out visor. However, when closed, it kind of flops back and can fall behind the edge of the carrier, getting in the way of the carrier release handle.

LATCH and Manual Storage


The center of the Willow base has a small pocket where the LATCH connectors reside when not in use. The box's cover has a finger hole to lift the lid off, and the connectors are tucked inside. The compartment works great for keeping things out of the way, but we suspect more than one parent has lost the lid as it is not fixed to anything.

The fabric on the Willow is soft but almost slippery in how it feels. This could make it easier to wipe clean.

Comfort/Quality


The Willow earned an above-average score for comfort and quality, and for the price, it is nice. However, if this is your jam, it isn't the top of the group.

Fabric and Padding


The Britax fabric is very soft, almost slippery to the touch. It feels like it would wipe clean easily for spills you catch quickly, and it is above average compared to the competition.

The padding is relatively plush and supportive, with pads on the shoulder and crotch strap. We wish the infant insert were a little more supportive, but most babies won't need it for long or ever, as the manual states it can only be used for babies up to 11 lbs.

The Willow suffers from the dreaded handle and canopy collision problem we see in a lot of infant car seats.

Handle and Canopy


The handle is plastic, with sharper edges that make it less comfortable to hold. It has no center grip or padding. The canopy looks nice when deployed but frumpier when folded. It is smaller than the average canopy on a car seat, and while it has a flip-out visor, it isn't enough to offer full coverage. While this might be fine for inside the car, it won't be great if you attach it to a stroller.

Shell


The Willow shell is solid and contained, with few places for grime to hide. It has the usual fare of warning stickers and information on how to use and install the seat. It feels like these seats get more cluttered every year, and we aren't a big fan of the look, but the information is useful and could be timely.

Weight/Size


The Willow is on the lighter side for the seats in the group, with a carrier weight of only 9.7 lb.


While this is not the lightest seat in the review, it is one of the lightest higher-ranking selections. If you plan to carry your baby in a car seat carrier, carrier weight could be a factor in deciding which seat to purchase.

Should You Buy the Willow S?


We like the Willow S and all it offers for the price. It is always nice to see you can get more and still save money. The Willow offers better crash test results and is easy to install using the LATCH. We think it is easy to use and lightweight enough for those who plan to carry their carrier with little ones inside. This high-ranking seat is one we think most families will love. The Willow is incompatible with many strollers, making it a no-go if your goal is to pair it with most strollers outside the Britax lineup.

What Other Infant Car Seat Should You Consider?


If you want the best car seat in the bunch, the Nuna Pipa RX is the top-scoring option in this group. The crash test results are impressive, and it is very easy to install. We like the comfort and quality and think there are features here for little ones and parents alike. If you are stressed about installation, the Clek Liing is one of the easiest to install and still has good crash test analysis results. If you hope to pair your car seat with a stroller, the Chicco Keyfit 35 is an easy-to-install seat with better-than-average crash test results. This easy-to-use seat pairs with lots of award-winning strollers from different brands when you purchase adapters.
