I'd love to have this kind of hammock in my garden someday. I would make it much "happier" though. More colors, twinkle lights and/or chinese lanterns, and higher, less contemporary, foliage would surround mine. ;]
For more berries, you should make sure to replace your entire bed after 3-5 years. Once the strawberry plants are older than five years, they start to decrease in productivity. By replacing your beds the younger plants will be able to take over and produce lots of new strawberries.
