Positive experiences with Maxi-Cosi Romi as a travel seat recommendation
We have a maxi cosi romi travel seat we use with our 2.5 yr old that is lighter [...] I just did my first flight with just the CARES harness and it was great! Super easy to use. [...] We got the Maxi Cosi Romi and it is by far my favorite travel car seat. Easy to install for quick trips and travel. It is also cheap. [...] It's only about 7ish lb, super easy to install with a lap belt, and it's free of fire retardant. Recently flew with it and couldn't be happier. [...] The pull strap to adjust the harnesses is a pain and doesn’t glide well. But it is tolerable since it’s not our every day car seat.

Recommendation for Maxi-Cosi Romi in small cars/apartments due to compact size and ease of use
We have the maxi cosi romi and love it. It is super lightweight and easy to install. We have a small car (Mazda CX-5) and it fits great. We also live in a small apartment and it’s easy to store. The only downside is the harness adjuster is a little stiff, but it’s not a deal breaker. It’s also really affordable.

Detailed comparison with Cosco Scenera and praise for flame-retardant-free materials
We got the Maxi-Cosi Romi as a travel seat and it’s been great. I was torn between this and the Cosco Scenera, but went with the Romi because it’s flame retardant free and has nicer fabrics. It’s super light and easy to install. The only thing is the harness is a bit hard to tighten, but I’ve heard that’s common with a lot of seats.

Consideration as a daily and travel seat, with comparison to Cosco Scenera and Nuna Rava
I'm trying to decide between the Maxi-Cosi Romi and the Cosco Scenera Next for a travel seat. I like that the Romi is flame retardant free and has a higher rear-facing limit (40 lbs vs 40 in). The downside is the harness adjuster is really stiff. We have a Nuna Rava as our primary seat so the Romi would be strictly for travel. For the price, I think it’s a solid choice.

Mixed review on comfort and comparison to Britax for travel use
I got the Maxi Cosi Romi as a travel seat but ended up returning it. My kid hated how upright it was and the padding is pretty minimal. We went with a Britax One4Life instead and it’s bulkier but way more comfortable for long trips. If your kid doesn’t mind a more upright position though, the Romi is super light and easy to carry.
