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.

Bouncer worked fine
Bouncer worked fine. Was a little worried when it showed up but it was perfectly fine!
less money less hassle
Found an item still in its original packaging for 2/3 of the original pricing.
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.
Stroller came super fast and I love it
Stroller came super fast and I love it
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.
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.
So grateful
Found what I needed at a price I could afford.
Great deal
Got a travel system for a great price. Would recommend Kidsy.
The products were very good
The products were very good. More than I’d expected them to be. The color of the diaper bag is beautiful and I know my daughter in love will be happy with it.
Looks unused
Couldn’t even tell the stroller had been returned.
Fast and efficient
Got my item fast and it was in excellent shape.
Would recommend
Already told two friends about Kidsy.
Great for parents
Shopping for gear doesn’t have to break the bank.
