Diono Quantum Stroller Features

3-in-1 Stroller

The innovative design enables the carriage to be transformed to a toddler seat by simply connecting 4 clips. Use the Quantum as a carriage in bassinet mode, as a full-size stroller in toddler seat mode, or as a travel system when you attach a compatible car seat for a complete 3-in-1 system! 

The Quantum’s convertible smart seat is suitable from birth; its flat bassinet with luxury mattress and reversible seat liner converts to an upright toddler seat / pushchair mode in an easy transition, and both options allow for world and parent facing. The best bit about the Quantum’s smart seat is that there are no extra parts to store, which is music to my ears. The XL seat has been tested for children up to 22kg, so it’s a buggy built to last.


Pushing the Quantum stroller feels super easy, from smooth to rough surfaces. It can be comfortably used on river sides, parks, etc.  With wheels in fixed position, it glides over stone filled pathways, uneven surfaces, etc. The wheels are also air-filled and great for all-terrain travel. 

Extra-large Storage Basket

The extra-large storage basket can be said to be a shopaholic’s dream feature for a stroller. The shopping basket is quite impressive in size. The Diono boasts of the fact that it has the space for a cabin sized luggage bag and yet integrated into the stroller’s easy fold.  For extra storage there’s also a pocket at the back of the seat unit which is big enough to fit a kids game, laptop, phone, etc


The one-hand recline is smooth and won’t rock or wake the baby up should you need to change position mid-sleep.

One-Hand Fold

A unique fold system, designed to fold at your pace, and effortlessly unfold.

One-step Brake 

Parents can say goodbye to scuffed and sore toes with the unique “one step brake”, designed for big boots, small shoes and is even flip-flop friendly! A simple step on, step off movement is all that’s needed to bring the stroller to a smooth stop! 

It’s a foot break and it has a one-step, push-on/push-off brake system, which is simple to use.

But it does need a firm push. And if, for whatever reason, you hang a nappy bag on the end of your buggy, you may find it harder to reach. But most importantly the brake works well.

Extra-large Canopy

The Quantum has been designed with a four-tier, eclipse canopy that protects against the elements. This canopy also includes a peek-a-boo window, ventilation panel for airflow, and pull down sun visor for maximum comfort all year long. Whatever the weather is, the canopy got it covered. It’s a four-tier canopy and best in its class. With the pull-out sun visor, it comes up and over the baby spanning the length of the carrycot. With this, you do not need to waste your money on strollers that don’t shade or fall off and it’s a great shield in short showers if you don’t have your rain cover.

It’s also brilliant at blocking out the light and creating the darkness for daytime naps while you’re out and about. Then there’s the mesh ventilation window and the peekaboo window my daughter loves. I could bang on about the hood for longer but I will stop there. 

Car Seat Ready

Quantum is car seat compatible with some strollers such as the; Cybex, Inglesina Zippy Strollers, etc. Adapters are included making it the perfect travel system for every journey.

Adjustable Handlebar

The Diono Quantum handle bar is perfect for tall parents. The 6 position handlebar means it’s perfect for adjusting to people with different heights. It is great for grip and it’s thick. The handlebar provides a comfortable grip that doesn’t quit and split over time. Height-wise it’s high even at its lowest point. The high handle bar has 6 different height positions.

  • Extra-large canopy.
  • Space-saving seat unit cleverly converts in carrycot,
  • Extra-large shopping basket
  • Ventilation mesh window.
  • Weighing 41 lbs, it’s quite heavy
  • Difficult to get up high curbs.
  • Magnetic peekaboo window cover flaps in the wind when open.

  • Another challenge is maneuvering the Quantum with one hand.
