Pushchair for short thighs but average torso

[Pancakefam]

Does anyone know of a pushchair with a shallow seat depth?

We currently have a silver cross zest and a Joie stroller for my 2 yo but both are too deep.

For my little one's knees to reach the edge of the seat, her back is forced away from the backrest and this puts her into an awkward position.. We used to keep the footrest horizontal but she's a bit big for that now and it also doesn't stop her shifting forwards.

Any ideas much appreciated..

place a cushion or rolled up blanket behind her?

I actually might try with a whole pillow, as I'm not getting very far with my search. Thank you for your reply @olympicsrock
