On a hot summer day, there is nothing like taking off your shoes or using sandals to expose your toes for a walk through a low garden or lawn. Taking it (literally) to the next level, sod-upholstered couches are a great way to cool down with a book in the backyard.
In Black Rock City, Nevada, this author even saw (and sat in) a grass couch set up in the middle of the desert – perhaps not the most sustainable design solution, but it sure was comfortable (and on very hot and dry days: even better when freshly watered).
Note: for most arid climates, it might be a bit more eco-friendly to just use something of the astroturf variety (though it sounds a little scratchy, to be honest). Still, it saves that pesky problem of trying to mow in difficult corners or up vertical green surfaces.
Best of all, though, anyone can build a sod sofa for themselves right at home – and perhaps an ottoman, coffee or side table to go with it. Build a pair of benches and you could make the perfect above-but-on-the-ground picnic spot.
