Generally 3-in-1 travel system pushchairs or prams are pricier than regular pushchairs or strollers. This is because these versatile buggies can also be used with a baby car seat or carrycot.
The average cost of the travel system pushchairs we've tested is £500. The cheapest is just £70, while big-name brands, such as Bugaboo, Cybex and iCandy, offer premium travel systems that cost more than £1,000.
Here's what you'll get, depending on your budget:
The cheapest travel system we've tested is usually £120, but it's currently on sale for £70. It's compatible with the Hauck Comfort Fix car seat (£90), making it a complete travel system for around £200, which is very appealing if you're on a tight budget.
Despite its low cost, it has adjustable handlebars and a one-hand fold - features typically seen on pricier travel system pushchairs.
If you're a frequent flier, the Cybex Eezy S is appealing because it's much smaller and lighter than traditional travel systems. It also folds down into a compact package that's small enough to be taken on some planes as cabin luggage.
Silver Cross travel systems tend to cost upwards of £700, but the Reflex is a third of the price and it's feature-packed.
It can be used with the Silver Cross Simplicity car seat, and it comes with a newborn head hugger in case you want to use the seat from birth, as well as a rain cover.
Most travel systems have a 15kg weight limit, which is around three years old, but the Reflex is suitable up until your child reaches 25kg, so it should last until your child no longer needs to sit in a pushchair.
You'll certainly turn heads with the eye-catching Cosatto Wow. On the Cosatto website it costs £600 for the carrycot and pushchair bundle, but it's currently available for £350 from some online retailers.
It can be used with the Port 0+ Cosatto car seat or Dock 0+ Cosatto car seat. You can also buy the multi-brand car seat adaptors (£30) to attach car seats from BeSafe, Cybex, Joie and Maxi-Cosi.
If you live in a rural area, you might want to opt for a travel system with chunky tyres and all-wheel suspension, such as the Maxi Cosi Nova 4 Wheels.
This travel system pushchair can be used with the majority of Maxi Cosi car seats. Alternatively, you can opt for the baby cocoon (£50) for your newborn to lie in, or the Maxi Cosi Oria carrycot (£169).
The Maxi Cosi Nova 4 Wheels travel system also boasts a unique hands-free folding system that's activated with your foot, so you can easily fold it even if your hands are full or if you're holding your baby.
iCandy travel systems can cost more than £1,000, but the Lime is one of the brand's more affordable pushchairs.
There's no need to buy a separate carrycot, as the seat can convert into a pram format, which means you also won't need to find space to store the carrycot when you no longer need to use it.
It comes with a number of accessories, including car-seat adaptors, seat elevators to raise the seat so it can be used as an impromptu highchair at restaurants, and a rain cover.
It has a built-in ride-on board so older siblings can hitch a ride, too.
Earlier this year, we asked 3,862 parents what they consider as 'essential features' when buying a new pushchair.
One in four parents told us that a compatible car seat was top of their list, and just over one in five wanted a corresponding carrycot to use with their pushchair.
But most important to parents is value for money, with 38% telling us it's one of their primary concerns when investing in a 3-in-1 pram.
