We picked up a s/h tandem recently and it came with an unbranded suspension seatpost on the rear that seems a little to firm given I ride with 9yo and 11 yo kids who are in the 30 to 40kg range
Had a quick google round and prices seem to run from £20 to "how much!!"
Anyone found/recommend a decently soft 27.2mm one at the lower end of the price range
It may be that the consensus is you get what you pay for, so happy to be advised that more is worth spending more here, but I think Thudbuster et al are out of budget
UPDATE: Had a go at pulling it apart and it looks like this a Kalloy one. Got the bottom adjuster off, pulled out a 2" black plastic spacer and another 5" cream/white spacer - can seem to get it apart any more. Stiction is real high so lubed with teflon spray but would like to strip it fully and see what condition its in - any ideas?
