Found an item still in its original packaging for 2/3 of the original pricing.

Great, trustworthy experience

Lydia M

Great deals, easy checkout with lots of payment options, shipped very quickly, and everything was packed well and looked exactly as it was described! I didn't end up needing any intervention with my shipping experience but appreciate the option to cover lost packages for a minimal fee, especially as we get into the late and lost package holiday season. I'll definitely be getting more of my baby gear from Kidsy.

Great price and fast delivery.

Quick response

Ordered a gate prior to this one, UPS lost it on route. I reached out to Kidsy via email and they secured a refund from UPS. Was hesitant to order again, but I couldn't find the gate at a more reasonable price. 2nd order arrived with no issues. Gate is sturdy and the dog (Husky) hasn't gotten through it (he's an escape artist). Quick delivery from start to finish.

I appreciated the detailed description, I knew I was getting a floor model and it came in perfect shape at a much reduced cost. When I thought the cupholders weren't included, I reached out to them and then we found them and they were very responsive and thankful that I let them know. Everything is fine.

Kidsy Customer Service Review

Josh Radcliff

Kidsy had a great selection of deeply discounted baby gates. Unfortunately, there was a piece missing when I received my package. I didn't realize it until after the 14 day return/exchange window. But I reached out, and they were willing to send me the piece anyway at no extra charge. I really appreciated the customer service.

Better than expected

Katie

Everything came packaged well, looked brand new. Super impressed.

Stroller came super fast and I love it

Watch Out For

mediumThe Aton M headrest is short, causing early outgrowing before the 30-inch height limit.
lowThe SafeLock belt tensioner on the base does not replace locking the seat belt; it must be locked separately.

Community Q&A

Does the Cybex Aton M SafeLock base fit the Aton G Swivel car seat?
No, the Aton M base is not compatible with the Aton G Swivel; they require different bases.
How well does the Aton M fit newborns under 7 lbs?
Reviews suggest it may not fit well for newborns under 7 lbs due to strap positioning, though Cybex has indicated possible updates.

Compared To

vs Maxi-Cosi Cabriofix

Cybex Aton M was considered alongside Maxi-Cosi for newborn use; safety and design preferences debated.

  • Cybex Aton G Swivel Discussion (related to base compatibility)

    I just bought the Aton G Swivel, but I had to return the SafeLock base because it wasn't compatible. The swivel base is totally different. Just a heads up for anyone mixing Aton models.

  • Cybex Aton M Safety and Fit Review

    From the car seat technician review: 'We found that it helps the fit to leave the insert in as long as is comfortable for the baby. I tried three babies under 7 pounds in the Aton M, and unfortunately the straps were not at or below the shoulders on any of them... The Aton M headrest has a slight downward angle which pushed his chin down and made him a bit crunched.'

  • Cybex Aton M vs Maxi-Cosi Cabriofix Comparison

    I'm torn between the Cybex Aton M and the Maxi-Cosi Cabriofix. I like the safety features on the Cybex, but I've heard the Maxi-Cosi is easier to install and fits smaller babies better.

  • Car Seat Recommendations Including Cybex Aton M

    I just want to make sure this fits our small car. We're leaning towards the Aton M because of the load leg and anti-rebound base. Would the SafeLock base be a good investment? We have two cars.
