Snappi Swirl family

Wheelbases & Interfaces

The Snappi, Cloud (Snappi interface version only) and Swirl chassis have been designed to accommodate an extensive range of seating systems, including our own Snappi (as shown in photo) and Modular seats as well as other companies’ modular/moulded seats. This flexibility ensures you achieve the necessary seat whilst retaining both the practical and visual benefits of a buggy.

Tendercare products are designed to be interchangeable and so the our Snappi and Modular seats all use the same Snappi interface and so, should the needs of a client change, you can simply swap the the seat and chassis (ensuring the seat and chassis sizes match) without the need for any parts. It really is that simple.

Chassis Sun & Rain Accessories

Sun and rain accessories can be tricky for custom, modular seating because each seat is built to the client's unique dimensions. To ensure a proper fit, sunhoods typically require modification at the point of manufacture.

Ideally, the seat manufacturer should handle the sunhood during production. Fitting the hood directly to the seat rather than the chassis ensures it sits at the correct back height for the user. If your seating is made by a manufacturer other than Tendercare, you may want to contact them directly to discuss the options available to you.

Below, we have listed the sun and rain options compatible with each of the three chassis when used with custom seating.

Adapted Sunhood for Snappi Chassis

Sunhood

We have made an adaption to one of our pushchair sunhoods so it can fit onto the chassis and be used with modular / third party seating.The hood can slide up the frame but we will fit best with back heights which look like the below image. The sunhood comes with a legcover to provide additional protection from the wind / rain.

All Transparent Raincover for Snappi Chassis

All-Transparent Raincover

A transparent weather cover designed to slip easily over the chassis and custom seat, offering complete rain protection without obstructing visibility. Not suitable for rearward (parent facing) facing Snappi chassis.

Cloud Chassis Sun and Rain Options

All-Transparent Raincover

A transparent weather cover designed to slip easily over the chassis and custom seat, offering complete rain protection without obstructing visibility. Not suitable for rearward (parent facing) facing Cloud chassis. Please note, the photo and raincover pictured is the Snappi chassis version. The design is very similar but we do not yet have this photo. This will be updated to the correct photo shortly.

Swirl Chassis Sun and Rain Options

All-Transparent Raincover

A transparent weather cover designed to slip easily over the chassis and custom seat, offering complete rain protection without obstructing visibility.
