Stocked my home for visits from the grandkids.

Found what I needed at a price I could afford.
Great deal
Got a travel system for a great price. Would recommend Kidsy.
Quick and easy
Couldn’t believe how simple the process was.
I appreciated the detailed description
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.
Perfect
Everything arrived exactly as expected.
Thank you!

I purchased a glider
I purchased a glider. It was described accurately, shipping was fast and price was great!
Great, trustworthy experience
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.
Highly recommend
A friend told me about Kidsy and I’ve already ordered twice.
Love my stroller

Would buy again
Everything was smooth and the item was as described.
Fast and efficient
Got my item fast and it was in excellent shape.
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.
So easy to use
Website is easy to use, items are great quality, and shipping is fast.
Amazing value
Saved a ton on a big item. Thank you, Kidsy!
Kidsy Customer Service Review
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.
