We're sort of in the same boat. Got the camper in April, panic bought everything we thought we'd need, then realised shortly after we only needed half of it.We've really struggled with chair choice.
We started-off with some that we used when we were tent camping - these were neither compact nor comfortable.
Then we bought some ultra portable ones - excellent for taking down to the beach, but difficult to get out of and too low for sitting at a table.
Then we bought some that promised a size/comfort compromise - these were fairly compact but only marginally more comfortable than our originals.
Now we've gone all-out for comfort (and sod the size) with the Zempire Halo chairs - they're really comfortable - and we also carry the ultra portables in the van just for beach use.
I'm really hoping we've cracked it now and that we won't have to buy any more bloody chairs!!
The chairs we currently have fold flat, but are just a cheap set of 2 from somewhere like b&m. They work well, just very uncomfortable
