As a car seat manufacturer, Britax uses innovation to create car seats that install easily. The Britax Galaxy360 Slim is their first rotating car seat on the market that has unique design features, though Britax engineers went into their archive to bring one back: the QuickStand that pops the seat forward and makes accessing the belt path ultra easy.

Rotating the seat is a smooth motion on its closed ring of “wheels-on-steel” and at 17”, the Galaxy360 is one of the narrowest revolving car seats. Britax uses their SafeWash fabrics on all versions of the Galaxy360, which means they’re flame retardant free and able to be machine-washed and dried. All of those features aside, how easy is it really to use?

ROTATION:

The rotation feature works by pressing in a trigger and pulling a lever just under either cup holder. Only one side needs to be engaged to rotate the car seat. It’s easy to do and the 2 steps keep the seat from accidentally being rotated.

360° ROTATING SEAT COMPARISON:

For additional info and to compare the features of the Galaxy360 to other rotating car seats, see our Rotating Car Seats Comparison article.

TETHER:

The tether is used in both rear- and forward-facing installations. Tether indicator shows red until tether is pulled snug enough. If it’s showing red, the Galaxy360 won’t rotate into forward-facing position. In my vehicles (Tesla Models X and 3) where the tether is routed to the side of the vehicle head restraint, there wasn’t quite enough pressure from the tether onto the indicator to press the indicator down to remove the red. I pressed the indicator in as I pulled the tether snug, which solved the problem. This is a vehicle-specific issue and shouldn’t affect a standard routing.

REAR-FACING INSTALLATION:

When the Galaxy360 was first released, parents felt the seat was overly reclined when rear-facing, even in the most upright allowed position. There was concern it took up a lot of front-to-back space. Britax extended the rear-facing recline range, allowing the Galaxy to be more upright and take up less of that front-to-back space. It was a wise move. This change is retroactive to all models; if your model doesn’t have the new labels on the seat and in the manual, please contact Britax.

In my unscientific experiment—I set my front seat in one location and didn’t move it—the Galaxy really doesn’t put the front passenger seat far forward, though, of course, your vehicle may vary. Leaving just enough room for it to rotate and not touch the front seat (roughly ½”), it took up the same amount of space as the Chicco Fit360 and Graco EasyTurn. Surprisingly, the Evenflo Revolve360 Extend in its most upright position was jammed into my front seat and scratched it as it rotated (my own fault: I didn’t want to move the front seat forward to get the Revolve into RF position). My point is that the Galaxy doesn’t take up any more space rear-facing than any of the more common rotating car seats, so let’s squash that rumor!

The recline angle adjustment is located inside the base, under the car seat. To access it, you must open the ClickTight mechanism on the side of the anti-rebound bar and lift the seat forward.

The ClickTight belt tensioning device is a lockoff, so there is no need to lock the seat belt retractor (see RF Installation with Seat Belt below). Remove the slack from the seat belt, then close the seat over the seat belt. Grab the car seat just above one of the rotation handles and give it a tug, about the force of a handshake, to see if it moves less than 1” side to side and front to back.

Always use the tether when installing the seat rear-facing.
Installation is fairly easy, though see comments below.

LATCH Weight Limits

Rear-facing LATCH weight limit: 30 lbs.
Forward-facing LATCH weight limit: 35 lbs

Center LATCH installations with Non-Standard Spacing (LATCH Borrowing)

Not allowed. Lower anchors must be spaced 11″ across.

Inflatable Seat Belt Policy

Not allowed.

Overhang

Overhang of up to 3” of the base off the vehicle seat is allowed in both rear- and forward-facing use.

RF Installation with Seat Belt:

In the owner’s manual, Britax allows locking the seat belt retractor after installing with a seat belt. This is to avoid possible strangulation risk. The ClickTight is a true lockoff and the installation is still safely secure if you don’t lock the retractor.

RF Installation with Lower LATCH Anchor Attachments:

The rear-facing LATCH weight limit is 30 lbs. If the rear-facing child weighs between 30-50 lbs., you must use the seat belt to install Galaxy. Do NOT use the LATCH strap and the seat belt together.

‼️ The lower anchor attachment strap (LATCH) is located in its compartment below the tether storage area on the back of the base that goes against the vehicle seat back. It is vitally important to your child’s safety that you take this strap and thread it through the belt path on the front of the base. It must go around the front of the base in order to hold the car seat securely in the vehicle! The small strap that holds the LATCH strap to the base is not designed to be a load bearing strap in the event of a crash.

FORWARD-FACING INSTALLATION:

🌟 Pro Tip: When forward-facing, the more reclined the Galaxy is, the better it will fit in vehicles with forward-leaning head restraints. If you find your Galaxy headrest is running into your vehicle head restraint as you rotate it, try adding more recline.

Use the tether when using the seat forward-facing! If you are already using Galaxy rear-facing, you hopefully will have already installed the tether strap. The tether strap storage location is on the back of the base. Attach the tether strap to the tether anchor behind the vehicle seat and pull it snug.

FF Installation with Seat Belt:

The seat belt installation is the same as rear-facing, but now you’re also making sure the tether strap is attached to the tether anchor in your vehicle.

FF Installation with Lower LATCH Anchor Attachments:

The LATCH installation is the same as rear-facing, but now you’re also attaching the tether strap to the tether anchor in your vehicle if it wasn’t already attached.

The forward-facing LATCH weight limit is 35 lbs. If the child weighs over 35 lbs., you must use the seat belt plus tether to install Galaxy. Do NOT use both the LATCH strap and the seat belt together. Store the LATCH strap back in its little compartment if you are installing Galaxy with seat belt.

‼️ The lower anchor attachment strap (LATCH) is located in its compartment below the tether storage area on the back of the base that goes against the vehicle seat back. It is vitally important to your child’s safety that you take this strap and thread it through the belt path on the front of the base. It must go around the front of the base in order to hold the car seat securely in the vehicle! The small strap that holds the LATCH strap to the base is not designed to be a load bearing strap in the event of a crash.

CHILD FIT:

The Galaxy has a head insert, middle infant insert, lower infant insert, and harness covers*.

Head insert: Use rear-facing only with children weighing less than 22 lbs. (optional to 11 lbs.); it MUST be used with the middle infant insert

Middle infant insert: Use rear-facing only with children weighing less than 11 lbs. (optional)

Lower infant insert: Use rear-facing only with children weighing less than 22 lbs. (required)

Harness covers: Use is optional; make sure they don’t interfere with chest clip placement at armpit level

I always suggest to parents that they remove the harness covers when the baby is a newborn. As a newborn, they’re still rolled up tight like a roly poly bug so there’s not a lot of real estate for proper chest clip placement, plus you as a parent are still learning how to tighten the harness properly. After a few weeks as they start to grow a bit, if you want to use the harness pads, go ahead and put them back on.

*The piece of fabric attached to the headrest that hangs down behind your child’s back is called the “Head Restraint Bib.” Once your child reaches 11 lbs., this bib MUST be unfolded and laid flat. Otherwise, when the headrest is in the lowest position, it should be folded behind itself.

There are 3 buckle positions from which to choose so your child isn’t sitting on the buckle. There aren’t any rules about which one to use: use the buckle slot position closest to your child’s body without being underneath them. The buckle strap is fairly short, especially with the lower infant insert in place.

Fit for an average-sized newborn is fine. Most parents switch to a convertible seat after using an infant seat, so fitting tiny babies isn’t a problem. I think 5 lbs. is a fair weight limit to start with given the size of the chest clip and padding.

Our model below is 17 mos old and fits beautifully. He has plenty of room to grow, but you can see that it is a narrow seat. A broad-shouldered child will feel uncomfortable in it toward the upper weight limits.

COVER/MAINTENANCE/EASE OF USE:

The cover can be thrown in the washing machine on gentle cycle and dried on low temps. The cover slides into a channel to make it look sleek, so it takes more time and effort to reassemble. A spoon or dull butter knife can help the process move more quickly.

As someone who reads manuals, I find it extremely frustrating to not be able to find the weight and height limits of the Galaxy360 listed explicitly within the first couple of pages of the manual. In fact, the first mention of the rear-facing weight and height limits were buried in the warning text on page 5. How many of us truly read a wall of text anymore (she asks in a wall of text—the irony is not lost here)?

The next mention of rear-facing weight and height limits was in the rear-facing child fit section on page 28, again in a wall of text. We can argue if it should be in text form or noted as we do at the top of our reviews (I’m partial to our format, obviously), but it’s useless if we can’t pull information out as we scan.

FAA/LIFESPAN/CRASH GUIDELINES:

The Galaxy360 is NOT FAA-approved. We always suggest using your car seat on the plane to not only keep your child safe during turbulence and runway incidents, but also to give you a break during the flight as well. It’s also safer for your car seat to be used on board rather than to risk damage from baggage handlers who are unaware how car seats should be handled or other baggage falling on them. The Graco Contender Slim and the Graco SlimFit3 LX are good travel choices.

This car seat has a lifespan of 10 years from the date of manufacture.

🚗💥🚙 Britax follows NHTSA guidelines for replacement after a crash.

The vehicle is able to be driven away from the crash site.
The vehicle door nearest the car seat is not damaged.
None of the passengers in the vehicle were injured in the crash.
If the vehicle has air bags, the air bags did not deploy during the crash; and
There is no visible damage to the car seat.

CONCLUSION:

Britax’s entry into the rotating car seat lineup, the Galaxy360 Slim, makes a great first impression with narrow, sleek styling, and comfortable padding. The Galaxy360 continues the Britax ClickTight tradition of “I can’t believe it was that easy” installations and the smooth rotation of the SwivelSmooth steel ring make the car seat lovely to use. Knowing that the fashions are all flame retardant free 🌿, and machine washable and dryable are the cherry on top.
