I concur O Wise One..the seat front raised and the inflatable lumbar support on my 2014 4/4 does the job.
People have asked what the rubber bulb used to inflate the support is for...depending on my mood the answer ranges from: urine exp-elation device or penis enlargement !!!!!
Sorry !!!
I would seriously worry when your passenger pumps it slowly whilst keeping eye contact..
I've been toying with tilting the seat up a bit at the front, too. We'll see how we fare on the 'Trip' and report back.
