The premium 316 stainless steel baseplate is an optional upgrade for the Riviera cantilever umbrella, making any installation onto a wooden deck or a concrete patio stronger.
A base plate is also great option if you are wanting to move a single Riviera between two locations. Moving between locations is best done seasonally, as the Riviera is a heavy umbrella and usually not frequently moved. Sometimes multiple umbrellas are the best solution.
