Hi Neil, not out at lustleigh yet then..?
we had the same model (edit but double trailer) for ours, (£69iirc) it survived both our two, and we’ve since lent it to 2 friends with kids, still going strong!
when they were really young we propped ours up with pillows etc to make them more comfy/safe, as it can get pretty bumpy and corners must be harsh for their little necks!
mine used to fall straight to sleep pretty much all of the time so it can’t have been that bad.
