Maxi-COSI Pria All-in-One Convertible Car Seat (SeaDrift)
The Maxi-Cosi Pria All-in-One Convertible Car Seat (SeaDrift) is a 3-in-1 car seat that transitions from rear-facing (5–40 lbs) to forward-facing (30–65 lbs) to belt-positioning booster (40–100 lbs), accommodating children from birth to about 10 years. Key features include soft, machine-washable fabrics made from recycled plastic bottles without added fire-retardant chemicals, a one-handed headrest and harness adjustment system, and a 3-position recline for improved fit and comfort. While many parents praise its comfort and plush padding, some report a strong initial chemical odor that may require airing out, and installation can be tricky for some vehicles, particularly achieving a tight rear-facing fit.

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.

Couldn’t even tell the stroller had been returned.
Bouncer worked fine
Bouncer worked fine. Was a little worried when it showed up but it was perfectly fine!

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.
Better than expected
Everything came packaged well, looked brand new. Super impressed.
Fast delivery
Order arrived in 2 days and looked perfect.
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.
Worth it
Got a like-new monitor for under $50.
Very happy
Really happy with my order. Shipped fast and clean.
Good stuff
Love the gear I got for my twins.
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.
Perfect
Everything arrived exactly as expected.
Good experience
Item arrived just as described. Couldn’t be happier.
Would recommend
Already told two friends about Kidsy.

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.

Does anyone have the Maxi Cosi Pria? General review request
I have the Pria 85 (older model) and love it. My daughter is almost 5 and still fits comfortably. The fabric is easy to clean and still looks great after years of use. No chemical smell on mine. I'd recommend.

FTM car seats - MaxiCosi Pria variations (va Halo) - Australia
I have the Pria and it's been great, easy to install, bub is very comfortable and it's not too big. The fabric is soft and seems good quality. I like that the cover comes off easily for washing.

Convertible Car Seat - Maxi Cosi?
I just bought the Pria all in one and it is SO comfortable looking. Babylist had it as the softest seat. I also love that the fabric is made without flame retardants. It does have a smell, but I put it outside for a week before installing and it was fine.

Maxi Cosi Pria car seat - smell and installation issues
I bought this seat because it seemed so plush and comfy, but the smell is awful! It's been 3 months and it still smells strongly of chemicals. Also, I cannot get a tight install rear facing. It wobbles so much I don't feel safe using it. I really regret this purchase.
