My softwood table is sitting on a paved area (so I would go for small pads under legs on grass) but Ive also added some scraps of teak scewed and gorilla glued to the feet as pads and the whole lot is sitting on nylon glides,,phew! That sounds complicated when spelt out, but the idea is to try to lift the softwood off the wet, the teak pads should be more durable and in any case could be cut off and replaced if they deteriorated,,,mind you its possible that moisture could find its way into the joint between the pad and leg and I will still find it rotting! But we do the best we can. I will report back on how its doing in 20 yrs,,
Steve.
