Maxi-Cosi Jay Plus Feeding Booster

The Maxi-Cosi Jay Plus Feeding Booster is a 3-in-1 feeding booster seat that straps onto a regular dining chair to bring your little one up to the family table for mealtimes. It's designed to grow with your child from around 6 months to 3 years, and it does more than one job: it works as a booster for meals at the table, converts into a floor seat for play and picnics, and comes with an attachable activity tray to keep small hands busy.

If you'd rather not commit to a full freestanding high chair — or you simply don't have the floor space for one — a strap-on booster like the Jay Plus is a compact way to give your baby a secure, upright spot at mealtimes. Premium details and a wood-effect finish help it sit comfortably alongside your dining furniture rather than sticking out as bulky baby kit.

Three uses in one seat

Maxi-Cosi calls the Jay Plus a 3-in-1 solution because it adapts to how your day actually runs. At the dining table it becomes a feeding booster so your child can join shared meals. Placed on the floor it turns into a comfortable floor seat for play activities and picnics. And the included activity tray clicks into the feeding tray to give your child something to explore — Maxi-Cosi notes it's intended to help develop motor skills and stimulate the senses during playtime.

Made to adjust as your child grows

The Jay Plus keeps up as your baby gets bigger. It offers adjustable height positions and two tray positions, so you can set the spacing to suit your child. The padded inlay adds comfort for younger babies, and when your child needs more room you can simply remove it to free up extra space. An adjustable 3-point harness helps keep your child seated, and rubber feet on the base are there to improve grip.

Easy to keep clean

Mess is a given at this stage, and the Jay Plus is built with that in mind. The inlay is removable and the surfaces are smooth, so day-to-day cleaning is mostly a case of wiping down. The tray surface is completely smooth with no crevices for food to hide in. A quick note on the tray: its removal-and-adjustment mechanism is made of metal, so Maxi-Cosi recommends wiping it clean by hand rather than putting it in the dishwasher, which could damage the mechanism or cause rust. The activity tray is also best washed by hand.

Fitting it to your dining chair

The Jay Plus attaches with straps that wrap around the seat and backrest of most dining chairs. For a secure fit, Maxi-Cosi recommends using it on chairs that are at least 34 cm wide with a backrest at least 21 cm high. Dining armchairs won't work, as the straps can't be secured around the seat and backrest. The tray is removable for easy installation, and when it's not in use it should be stored separately rather than on the seat — it's flat and compact, so it won't take up much space.

How it Works

• Booster mode: Attachment straps wrap around the seat and backrest of a suitable dining chair, and the 3-point harness holds your child in an upright seated position at the table.
• Floor seat mode: Placed directly on the floor, the rubber feet on the base help prevent sliding so your child has a stable seat for play.
• Activity tray: The activity tray clicks into the feeding tray; to remove it, you pull and lift the two strips on the activity tray.

Best For

The Maxi-Cosi Jay Plus Feeding Booster is a great option for parents who:

• Want to bring baby to the family dining table without a full freestanding high chair
• Are short on space and prefer a compact, strap-on booster
• Would like one seat that doubles as a floor seat for play and picnics
• Have a child from around 6 months to 3 years (9–15 kg) who can sit unaided and hold their head up

It may not be the best fit if you:

• Only have dining armchairs, or chairs narrower than 34 cm or with a backrest under 21 cm
• Prefer a standalone high chair with its own frame and base

Disclaimer

Your child can start using the Jay Plus once they are able to sit unaided and hold their head up on their own — this usually happens at around 6 months, though every child is different. Always attach the booster securely using the straps so it can't move, and keep your child supervised during meals and play. The tray is not a restraint. In floor seat mode, only use the Jay Plus on the floor and never on a table or other raised surface.
