Can outdoor furniture be put on the grass?

We don’t have a patio and I have no idea how to build one without interferring with other existing structures. We’d like an outdoor sitting area, though. Can outdoor furniture be put just on the grass? If so, does it matter what kind?

Please don’t suggest picnic tables. They’re too hard on my husband’s back.
