Happy Hips Service

Car Seat for Babies with Hip Dysplasia

 

If your baby has been diagnosed with Hip Dysplasia, finding a safe and suitable car seat can feel overwhelming. Babies undergoing treatment often need extra leg space and support, and adapting a standard car seat with towels or cushions can be unsafe.

The Maxi-Cosi Happy Hips Service supports UK parents by providing a car seat designed specifically for babies receiving treatment for Hip Dysplasia, helping you travel with confidence and peace of mind.

Why standard car seats aren’t suitable for Hip Dysplasia

Babies with Hip Dysplasia have specific positioning needs during treatment. They often require:

  • additional space to support correct leg positioning
  • enhanced back and body support
  • a secure and stable seating position

Standard car seats are not designed to meet these needs. Having the freedom to travel safely with your baby during treatment is essential for family life, whether it’s getting to appointments or simply maintaining daily routines.

The Maxi-Cosi Happy Hips Service

At Maxi-Cosi, child safety is at the heart of everything we do. That’s why we created the Happy Hips Service — a UK loan service that helps families access a car seat suitable for babies with Hip Dysplasia during treatment.

Designed with medical specialists

Working closely with medical specialists in baby Hip Dysplasia, our engineers adapted one of our trusted car seats to meet the unique needs of babies undergoing treatment, without compromising on safety or comfort.

 

Maxi-Cosi Opal HD car seat

Based on the Maxi-Cosi Opal, the Opal HD has been specially adapted to provide:

  • extra leg space to support Hip Dysplasia treatment
  • improved back support and comfort
  • Maxi-Cosi safety standards you can trust

Through the Happy Hips Service, UK parents can borrow the Opal HD and feel confident their baby is travelling safely on every journey.

How the Happy Hips Service works

The Happy Hips Service is designed to be simple and accessible:

  • A £120 refundable deposit is required
  • £10 is deducted per month (or part-month) the car seat is used
  • Any remaining balance is refunded once the seat is returned in good condition

This allows families to use a Hip Dysplasia car seat without the need to purchase one outright.
