A raised bed is ideally 18 - 24 inches deep, but if you are building your raised beds on top of existing earth you wilI have some leeway here. I have successfully gardened in boxes built over earth with only one foot of soil depth. You can find both detailed instructions for building a raised beds and multiple choices for buying raised beds here.
Raised beds offer excellent drainage. Soil compaction in no longer an issue, so working the soil and weeding will be much easier. Every square inch of soil will go towards food production as none will be wasted underfoot. Depending on how high you choose to build your raised beds, you could completely eliminate the need to bend over. At worst, even if your raised beds are only a foot and a half high, you would not be bending as far.
