If you’ve ever tried to load a wiggly toddler into a car seat in a tight parking spot, you already understand why rotating car seats are having a moment. The ability to turn the car seat toward you changes everything...less twisting, easier buckling, and a smoother daily routine. Two options you may be considering are the Joie Pepper Spin SI and the Joie Matcha Spin SI. Both offer that highly sought-after 360° spin, but they’re designed for slightly different needs. Let’s break it down.
What Makes Rotating Car Seats Different?
Rotating car seats (also called swivel car seats) allow you to turn the seat toward the door to lift your child straight in and out, buckle them while they’re facing you, reduce strain on your back, and help older kids climb in more independently. This can be helpful for any caregiver. But even more so for caregivers who are short or have disabilities that make harnessing a child in the traditional way difficult. They can also be a good option for children with disabilities that limit their mobility.
Both the Pepper and Matcha Spin SI offer full 360° rotation in harness modes, 180° rotation in high-back booster mode for independent entry, and easy-to-reach turning activators on both sides

Key Features:
4-in-1
Rotation in multiple modes
GrowTogether™ system
AutoClick™ magnetic chest clip
Removable cup holders
LockTight™ belt tensioner + lock-off for secure installation
The Joie Pepper Spin SI is a 4-in-1 rotating car seat. It has a rear-facing mode, forward-facing mode, high-back booster mode, and a backless booster mode. The rear and forward-facing modes feature 360-degree rotation. But keep in mind that the top tether cannot be used rear-facing, which means you will need to reinstall the seat to use it forward-facing, since you do want to add that top tether! Learn more about top tethers here. The high-back booster mode features 180-degree rotation. The backless booster mode does not have a swivel function, as it actually slides off of the main portion of the seat! But there is no need for a swivel function in backless booster mode anyway.
The Joie Pepper Spin SI has a GrowTogether system. This consists of a 15-position headrest with a no-rethread harness. The harness has an AutoClick magnetic chest clip that helps simplfying the buckling for adults, while still being a challenge for houdini toddlers to figure out how to unbuckle!
The Joie Pepper Spin SI has 4 recline positions for the rear and forward-facing harness modes. When installing the seat rear or forward-facing, make sure to check the recline indicator window to ensure that the bubble is fully within the white line. The LockTight belt tensioner and lock-off help caregivers achieve a secure installation with minimal effort.
The Joie Pepper Spin SI also has cup holders that remove with the push of a button and are easy to clean in the dishwasher. It meets the FMVSS 213a and 213b standards. This means that it has passed the side impact standards and the new frontal impact standards as well. It features side impact pods and bolsters that ensure side impact protection from the child's head to their hips. The side bolsters are required until the child is 40 pounds.

Key Features

Rotation in multiple modes
GrowTogether™ system
AutoClick™ magnetic chest clip
Removable cup holders
LockTight™ belt tensioner + lock-off for secure installation
The Joie Matcha Spin SI offers the same core rotating functionality as the Pepper SI, but lacks the backless booster mode. However, don't let this deter you, as Joie makes a fantastic stand-alone booster option, called the Joie Basil Backless Booster!
The Joie Matcha Spin SI has a rear-facing mode, forward-facing mode, and a high-back booster mode. The rear and forward-facing modes feature 360-degree rotation. But keep in mind that the top tether cannot be used rear-facing, which means you will need to reinstall the seat to use it forward-facing, since you do want to add that top tether! The high-back booster mode features 180-degree rotation.
The Joie Matcha Spin SI has a GrowTogether system. This consists of a 15-position headrest with a no-rethread harness. The harness has an AutoClick magnetic chest clip that helps simplifying the buckling for adults, while still being a challenge for Houdini toddlers to figure out how to unbuckle!
The Joie Matcha Spin SI has 4 recline positions for the rear and forward-facing harness modes. When installing the seat rear or forward-facing, make sure to check the recline indicator window to ensure that it shows completely white. The LockTight belt tensioner and lock-off helps caregivers achieve a secure installation with minimal effort. The LockTight belt tensioner on this seat is slightly different than the one on the Pepper, but we have found both very easy to use!
The Joie Matcha Spin SI also has removable cup holders that are easy to clean. It meets the FMVSS 213a and 213b standards. This means that it has passed the side impact standards and the new frontal impact standards as well. It features side impact pods and bolsters that ensure side impact protection from the child's head to their hips. The side bolsters are required until the child is 40 pounds.
Pepper vs Matcha Spin SI: Key Differences
Biggest difference comes down to longevity:
- 4-in-1 (includes backless booster)
- up to 120 lbs
- designed for full car seat journey
- 3-in-1 (no backless booster)
- up to 100 lbs
- covers most stages, but not all
Everything else - rotation, safety features, install support - are all very similar.

A Note on “The Best” Rotating Car Seat
There isn’t one best car seat for every family. The right choice depends on your child’s size and growth, your vehicle, and your family's specific needs.
Both of these options featured in this post are easy to use and long-lasting.
No matter which seat you choose, proper installation, correct harness fit, and using the right mode at the right time will always matter more than any single feature.
Final Thoughts: Pepper vs Matcha Spin SI
If you’re deciding between the Joie Pepper Spin SI and Matcha Spin SI, the biggest difference comes down to how long you want the seat to last.
- Choose Pepper Spin SI if you’re looking for a true one-and-done seat that takes you all the way from the rear-facing through backless booster stages.
- Choose Matcha Spin SI if you want a simpler rotating option that still covers the major stages, just without that final backless booster step.
Both seats offer:
- the convenience of a 360° rotating car seat
- updated safety features
- thoughtful design that makes everyday use easier
And that’s what really matters.
One More Thing to Keep in Mind
The “best” rotating car seat isn’t about having the most features, it’s about finding the right fit for:
- your child
- your vehicle
- your daily routine
Because even the most advanced car seat only works if it’s installed correctly, used correctly, and fits your life.
