My take on the KidFit Zip Plus 2-in-1 Belt-Positioning Booster Car Seat
The Zip Plus suits a family that wants the KidFit high-back to backless design with extra quilted cushions that zip off for cleaning. Chicco lists it at 10 lb and 17 in x 17 in x 26 in. The KidFit Zip Air Plus shares its manual but adds 3D AirMesh and a zip-on leg rest, and Chicco lists it at 11 lb with a 20 in depth.

Who the KidFit Zip Plus 2-in-1 Belt-Positioning Booster Car Seat fits
This seat covers 2 stages, and a child has to meet every limit of the stage they are in. Check the date label on the shell before using a hand-me-down; every seat has an expiry.
High-back booster40 to 100 lb · 44 to 57 in · from 4 years
The seat’s own back and belt guide route the vehicle belt across the shoulder, and the sides give the child something to lean on when they sleep.
Backless booster40 to 110 lb · 44 to 57 in · from 4 years
Only the base is left, so the vehicle seat has to support the child’s back and head, and the belt guide sits at the hip.

How the KidFit Zip Plus 2-in-1 Belt-Positioning Booster Car Seat installs
Lower anchors
Quick Release LATCH. Check your vehicle manual for which seating positions have anchors, and switch to the seat belt once the child passes the anchor weight limit in the manual.
Recline
2 recline positions. The recline angle is what keeps a young baby’s airway open, so set it before tightening the install.
Every install is a fit between one seat and one vehicle. Read both manuals, and use a free inspection station if anything is unclear.
Will it fit your car?
At 17 in at its widest, this seat is one of the narrower ones in its class and is a candidate for three across in many mid-size cars. It weighs 10 lb, which matters if you will move it between cars or carry it through an airport.
Check your vehicle manual for lower anchor positions and any head-restraint rules.
Rear-facing seats need front-seat room: try the install behind the driver before you commit.
Not certified for aircraft use: plan on gate-checking it or using a different seat to fly.

What to know before you live with it
Installing it with or without LATCH
The child is always held by the vehicle lap and shoulder belt. LATCH only holds the booster and is optional. To use it, pull the LATCH release handle, pull out both connectors, clip them to lower anchors at the standard 11 inch spacing, then pull the adjustment strap while pushing the seat back. If you do not use LATCH, the manual says to pull the strap snug so the connectors stay clear of the belt. The top tether anchor is not used. To remove the seat, pull the release handle while pulling the booster away from the vehicle seat.
In high-back mode, the backrest locks in 10 height positions. The shoulder belt goes through the orange guide, which should sit at or just above the shoulders, and the child's ears must be below the headrest. The lap belt passes under the first armrest, and both belt parts pass under the armrest nearest the buckle. In backless mode, the shoulder positioning clip, stored under the seat, stays in use until the belt lies flat across the center of the shoulder on its own. The manual forbids pillows or blankets between the booster and the vehicle seat, and lap-only belts.
Chicco describes quilted seat and backrest cushions that zip on for extra padding and zip off for cleaning or storage, plus an ErgoBoost Plus seat with triple-foam padding. All fabrics, including armrest covers, are listed as removable and machine washable. The care note says to close any hook and loop fasteners, wash fabrics separately in cold water on a delicate cycle with mild detergent, avoid bleach and hang dry. Two dishwasher-safe cup holders fold in, and a bonus kid console fits into either one.
Both seats use the same KidFit Zip manual and the same child limits. The Zip Air Plus product page lists 3D AirMesh channels in the backrest and seat and a zip-on cushioned leg rest. It gives an assembled size of 20 in x 17 in x 26 in and a weight of 11 lb, against 17 in x 17 in x 26 in and 10 lb on the Zip Plus page. If front-to-back space on the vehicle seat is tight, I would measure against the Zip Air Plus depth before choosing it.
Is the KidFit Zip Plus 2-in-1 Belt-Positioning Booster Car Seat recalled?
No campaign in the current NHTSA child-restraint data names this model family, and I have not run a separate review for it. Check your seat’s model number and date of manufacture before use.
KidFit Zip Plus 2-in-1 Belt-Positioning Booster Car Seat: common questions
What are the KidFit Zip Plus limits?
At least 4 years old and 44 to 57 in tall. High-back mode is for 40 to 100 lb, backless mode for 40 to 110 lb, and the child must be able to sit still with the belt correctly placed for the whole ride.
The manual allows hand washing with mild soap or a cold delicate machine cycle with mild detergent, then hanging to dry, and says to hand rinse the foam insert. For the removal steps it refers you to the Chicco website or 1-877-424-4226. Do not use bleach, and do not put soaps or lubricants on the LATCH straps.
Does the KidFit Zip Plus have to be buckled in when empty?
Yes, it must be secured when unoccupied. The manual says LATCH is adequate for the backless booster, but the lap-shoulder belt should be used to secure the high-back booster.
