I have 5 kids (11 mo. to 5 yrs.) so we are rather familiar with using playgrounds! By far the best surface material you can get is recycled tire mulch. It is comfortable to walk on, won't degrade, and makes good use of scrap rubber. The civil engineers in my firm spec this most often for elementary and municiple playgrounds. IF I recall correctly, the stuff that looks like bark mulch goes for a premium of $400/yd or thereabouts. The stuff that looks like shredded tires is dirt cheap, which I guess is quite literal in this case. The expensive stuff is treated with anti-microbial coatings and such. Otherwise, well rounded uniformly sized peastone feels pretty good to fall on as a number 2 choice. If you're looking for swingset/playscape ideas, details or structural considerations, I built countless hundreds of them through my teenage years. Despite this, my kids swing on a 16' pair of 2x10s lagged into some trees, and a slide that rests on a 4' high stump with some rungs!
