The saw horses are the plastic folding type to be found at most big box hardware stores. They are made to lay flat for easy storage. I had used timbers for beds in years past but the various types of stone work better when stacked and eliminates lots of termites. We have a revolving contract with a termite prevention company so it makes no sense to have old lumber all over the yard. At near 76, my brain writes lots of checks my body can't cash but gardening keeps me busy and in good shape.
Add: I just checked our local Lowe's and they have the plastic folding sawhorses in a 2-pak for $25. Should be close to that price in any major home improvement/hardware store.
