Introducing carrycot plus

Innovation at its best, carrycot plus delivers; one base, two fabrics sets, and three parent facing solutions. Incredibly adaptable and designed with your baby’s comfort in mind, carrycot plus easily adjusts from lie-flat mode to incline mode, offering a perfect recline for babies who suffer from reflux. The interior of carrycot plus is Oeko-tex certified, meaning your baby is resting safely in a roomy, chemical free environment, while the exterior 3D mesh fabrics offers improved breath-ability and airflow.

A liner under the carrycot mattress acts as a winter layer to further protect your baby from cold elements. Simply remove as the weather warms. 

Once your baby can hold their own head up and is ready to see more of the world, convert carrycot plus into a rear facing seat, with the easy switch of fabric sets.

Comfort features for baby

Large, individual 600D canopies with a UPF 50+ rating and flip out sun visors, protect your babies as you stroll, and a peek-a-boo flap quietly allows you to keep an eye on them from above. The duet buggy’s wipe clean polyester fabric is super lightweight, water repellent and durable, and zips easily off the buggy frame.

Padded, tail free harnesses keep your babies secure in their buggy seat and are easily adjusted as they grow. The seat positions transition from full recline for a newborn baby to upright for an older child, and a convenient ‘gate’ opening bumper bar allows you to easily get your babies in and out of the buggy.

duet now comes with a reversible, coloured seat liner for the enhanced comfort of your baby.

mountain buggy duet


The buggy was great initially handles really well and the width is great but my twins are only 7 months old and we've had to buy new tyres and inner tubes for 3 of the wheels. The tyres have completely split and fallen apart and of course they're not covered by the warranty.
