LiquidSeat has a built-in weighting system so there is nothing to do except throw it in the pool when you are ready to use it. Easy as that! It can be used as a seat IN and OUTSIDE of the pool. Once thrown in the pool, the LiquidSeat will self right itself. There are small holes in the top of the seat that let the water flow through that allow it to sink. The weight at the bottom causes it to sit properly at the bottom of the pool.
One big advantage of the LiquidSeat is that it can be removed from the pool at anytime and stored. It is easily stackable outside the pool when not in use. With traditional built in seating, the seat can not be removed and the pool cleaner can easily get wrapped around it.
