Best lightweight buggy for 2-4 year old?

[Kowr]

hello,
what are your recommendations for a lightweight buggy to walk 15 mins and back to the nursery, would need to fold up quickly and easy and not take up too much space.
must have a rain cover option and ideally fold vertically if you know what I mean.
we’ve got a silver cross huge thing which is fine but we can’t fit it in the nursery shed easily.
would love it to be suitable for our 2 year old and she will need it until preschool (4 ish?)

I have a Bugaboo Bee and absolutely love it. Lightweight, easy to push and steer, parent and world facing option and great basket space, it folds in one piece quickly and can be done one handed. Both my 10 month old and 2.5 year old love it (use it separately of course). It can be used from birth up to 4 years old. Bought ours brand new and it comes with it's own rain cover included in the box.

I’ve got a joie nitro one. They’re about £70 and come with rain over etc. am really pleased with mine, use it for school run and on holiday recently
