While this patio is clearly a deck for a tropical resort, it still has some good ideas using this wicker furniture that you may use for your own residential patio or courtyards.
As with all types of garden design, consistency and repetition of elements helps create unity and continuity. In this design, the furniture as well as the trees and other plantings are matched and spaced uniformly. Uniform spacing isn't necessarily important but does help if you're looking for a symetrical element.
And of course, all things combined with the wicker furniture and especially the palm trees and plants is what gives this deck patio and tropical landscaping its tropical flavor. It's the same with all design styles and garden themes. Many times, simply changing the type of plants will change the entire atmosphere of a garden or landscape.
