All terrain pushchair with very upright seat?

[YouHaveNoAuthorityHereJackie]

I’m looking for the above and my search is proving fruitless. My dd has incredibly bad reflux problems which don’t always respond to medication. We are very outdoorsy but recently she’s been screaming when in the buggy. She’s child number 4 and over the last 15 years with the others I’ve had various great buggies but all seem to have the kind of seat that doesn’t quite sit upright. Right now we have a Thule Urban Glide which I love as it’s so light and easy to push over really rough ground, but it doesn’t sit upright, and in the past we’ve had a Mountain Buggy, which again was fantastic but I hear the build quality of newer ones isn’t what it was. Open to any suggestions as this is really causing a problem for us now and it’s horrible to see dd so uncomfortable. She’s almost 2 but very small, only just 20 pounds. I’d love to carry her as I did with my others but I have back and hip problems now so please no sling suggestions, I promise I’ve tried! Our everyday town buggy is a Bugaboo Buffalo which is great as it sits bolt upright, but despite it being ‘all terrain’ it’s not going to stand up to the forest trails and beaches I want to take it on. Any ideas? Something available second hand probably preferable as she’s an independant little thing and won’t be in it past about the next year I’d imagine. Thanks x

Bugaboo fox?

Our Phil & teds had a very upright position but you’d need to check newer models.

Thanks for the suggestions. We actually got rid of a Bugaboo Fox in favour of the Buffalo, it felt so flimsy in comparison and go’s knows why they market it for all terrain. The Buffalo is great, so sturdy but I still wouldn’t want to take it into the forest. The Phil and Teds is a good shout, I had one back when dc 1&2 were tiny and they were new in the country then and quite novel. I think that did sit quite nicely upright, I’ll have a little look.

We test drove a Phil & Teds sport alongside a MB urbagn jungle. The difference in lightweightness and apparent build quality was heavily in the MB's favour.
If you liked the MB's upright position before, maybe don't rule it out. Is there anywhere you can try them out?

Can you get an old bugaboo runner frame and use your bugaboo buffalo seat on it?

I have a icandy peach all terrain which I got second hand. The seat you use from 6 months sits very upright
