The most common floats for children and adults are

, they are much less dense than water because they are composed mainly of air, surrounded by a thin layer of synthetic material.
Float-assisted swimming can be more difficult than free swimming, because if the float is held in front of the swimmer a more vigorous workout for the legs is given as the swimmer's weight is propelled solely by the legs, and vice versa for the arms.
Swimming board
Swimming boards (often referred to as kickboards or flutter boards) are a flotation aid used for fun or to develop a swimmer's kicking action. They can be used on all strokes but are primarily used on

Swimmers of all ability can use them. Young swimmers can develop their kicking action while elite swimmers can refine their kick. They are also used to strengthen a swimmers' legs.

Construction
Kickboards are usually made from EVA foam
Ethylene-vinyl acetate (EVA), also known as poly (ethylene-vinyl acetate) (PEVA), is the copolymer of ethylene and vinyl acetate. The weight percent of vinyl acetate usually varies from 10 to 40%, with the remainder being ethylene. There are thr ...
. Some are made of more durable HDPE
High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a thermoplastic polymer produced from the monomer ethylene. It is sometimes called "alkathene" or "polythene" when used for HDPE pipes. With a high strength-to-density ratio, ...
. The EVA foam boards can break easily and become very worn after long use. So it causes the board to slowly disintegrate over time.
Variations
There are some variations of kickboards from the traditional form with two hand grips. Some can be used as a kickboard and a pull buoy
A pull buoy or leg float is a figure-eight shaped piece of closed-cell foam used in swim workouts. Swimmers place the buoy between their thighs or their ankles to provide support to the body without kicking their legs; this allows the swimmer to ...
. These are often oddly shaped so they can be used for both of the training aspects.
Other floats
Especially-large floats can be used as seats to float or sit on top of a pool for the user to stand on top in the manner of a raft
A raft is any flat structure for support or transportation over water. It is usually of basic design, characterized by the absence of a hull. Rafts are usually kept afloat by using any combination of buoyant materials such as wood, sealed barrel ...
