They look like a useful shop, quite expensive for the grade of foam I need though. I've been onto ICE and they can send new pads out so I'll go with those.
Incidentally we've decided to sell this trike. It wasn't the plan when I started the refit but it's something we've been mulling over for a few weeks now. We have 3 tandems now and with the daughter no longer interested in riding with us we'll never go out on a pair of tandems again so 3 seems a bit excessive.
We've decided that it will be the Trice that goes because we haven't found it to be very practical, its 100mm wider than a Sprint which is enough thwart it at every Sustrans gate in the UK, and even, as Mrs. B discovered a couple of years ago their Dutch equivalents.
I get the ad up on the for sale board later.
