What do you recommend for soft ground?

"What do you recommend for soft ground? Our backyard is covered with mulch. I'm worried about the stability and longevity of the trampoline."

If your trampoline will be installed in an area of the yard where grass isn't present, mulch is preferred since it keeps the trampoline from sinking into the mud which is the chief concern. If the mulch is becoming too soft, you can try elevating the frame with a combination of woodblock/mulch or or opt for rubber mulch or even faux-grass/astro-turf tiles to support the areas where the frame contacts.
