5-Point Harness: A 5-Point Harness has two shoulder straps, two hip straps and a crotch strap.  Child Passenger Safety experts agree that the Five-Point Harness is the safest, because it provides the snuggest fit and is suitable for the widest range of children.

Adjustable footrest: As the name suggests, an adjustable footrest can be adjusted so that baby’s legs are bent in a sitting position, or extended so that baby’s legs are supported while he is reclined for a nap.

All-terrain: As it relates to strollers, “all-terrain” implies air-filled rubber tires, true wheel suspension and an increased frame durability to handle the challenges of rough terrain.  However, “all-terrain” has become somewhat of a buzz word that stroller manufacturers like to use, so review the stroller specs carefully.

Bassinet (or Carrycot): Akin to the pram, a bassinet is a cot so baby lies flat in the stroller.  Unlike the pram, a bassinet is removable from the stroller base so that a sleeping baby can be quietly transported.  As baby grows older, the bassinet can be replaced with a toddler seat so he can watch the world go by.

Belly bar (or Bumper bar): A belly bar is a bar attachment that is belly height on baby when he is seated in the stroller.  It provides added protection to ensure baby doesn’t fall out of the stroller seat, and it helps baby pull himself upright to look around at the world going by.  Belly bar accessories are typically found on all-terrain and jogging strollers, which have deeper bucketed seats.

Fixed wheels: A fixed wheel does not swivel or pivot, and remains fixed in the straightforward position.  It is ideal for avid runners who want to hold a sure and steady straight line during their workout.

Foot muff: A foot muff is like a mini, stroller-size sleeping bag for your little one to protect from the cold.  It has holes that allow for the attachment of the harness while your little one is nestled inside.

Hand brakes: A hand brake is a bicycle-style brake that is located on the handlebar.  This brake applies stopping power to the front wheel of the stroller.  Hand brakes are usually found on jogging strollers.

Infant seat (or car seat) adaptor: Some strollers are able to accommodate an infant seat, but require a separate and additional accessory to do so- the infant seat adaptor.  Infant seat adaptors are not universal- stroller manufacturers have produced specific adaptors for their stroller models, and not all infant seats are compatible with all adaptors.  Be sure to check your specific stroller model and infant seat if this is a concern.

Lockable wheels: Lockable wheels can swivel for better maneuverability and everyday use, or they can be locked into the straightforward position for light jogging and rough terrain.

Parking brakes: A parking brake is meant to keep a stroller from moving.  When engaged, it keeps your stroller from rolling back and forth while you are loading or unloading your little one.

Pneumatic wheels: Pneumatic wheels are air-filled rubber tires.  They are heavy and prone to deflation or tearing, but they result in a super smooth, whisper-quiet ride.

Pram: A pram is an old-fashioned buggy, with a cot for baby and no upright seating.

Quick release wheels: Means that the stroller wheels can be removed easily.  Quick release wheels are a useful feature for those who travel with their stroller. Easy storage in back seats, hatch-backs, and trunks of cars may require you to remove either the front and/or back wheels of the stroller.

Reversible handle: A reversible handle means that the stroller handle can be positioned so the seat is facing forward in the direction of travel, or positioned so the stroller seat is facing inward toward Mommy.  This feature achieves the same effect as the Reversible Seat, but has an advantage in that the child does not need to be removed from the stroller to make the switch.

Reversible seat: A reversible seat means that the stroller seat can be positioned so it is facing forward in the direction of travel, or positioned so that it is facing inward toward Mommy.

Ride-on board: A ride-on board is a board with wheels that attaches to the rear axle of the stroller so that an older child can stand and ride along.  Some stroller manufacturers produce ride-on boards as an added accessory for their strollers, while others make strollers with a built-in ride-on board (also called a “Sit and Stand” stroller)

Rumble seat: A rumble seat is an add-on seat which allows a single stroller to carry 2 children at once.  Depending on the stroller model, the rumble seat may attach to the base of the stroller up front or behind the main stroller seat.  Rumble seats are usually for children that are at least 6 months of age.

Suspension: When a stroller has a suspension system, it means that it was built with a spring mechanism in the wheels or frame which absorbs the bumps you encounter, resulting in a smoother ride for your child. Strollers can have front wheel suspension, back wheel suspension, or both.

Swivel wheels: A swivel wheel swings freely. A swiveling wheel improves maneuverability, and allows better negotiation of tight corners for everyday use.

Tandem stroller: This term applies to multiple-child strollers, and means that the passengers are in front or behind each other, rather than side-by-side.

Toddler seat: For stroller models that have a bassinet option, once your child is old enough to sit upright he is old enough for the toddler seat.

Travel System: A Travel System includes a standard stroller, a coordinating infant car seat and often the infant seat base for the car. The infant seat snaps into the stroller, allowing you to transport your sleepy infant from the car into the stroller without any disturbance. Then, once your child is old enough to support himself, he can enjoy the stroller without the infant seat.
