The article considers the experience of studying the design capabilities of colored plastic in the process of designing furniture for pool locker rooms. Colored plastic is one of the most popular materials - it is a modern, environmentally friendly, and characterized by high impact resistance, resistance to abrasion, and the action of hot and detergent materials. Furniture made of plastic is inexpensive, lightweight and easy to carry; it is stabile, it is resistant to rotting processes, insects and fungi. It is not able to swell or deform under the influence of moisture. Such furniture is easy to care for. Furniture for children is often made of plastic, because it is characterized by low weight and the absence of sharp corners. Due to this, the risk of injury by contact with it is significantly reduced. These advantages have stimulated us to find ways to expand the scope of use of plastic and furniture made of it. A visit to the pool prompted us to use this material for designing furniture for locker rooms for mothers and babies, because it is plastic that is the most suitable option for this subject - spatial environment. A team of teachers and students conducted experimental work to study the possibilities of using colored plastic in furniture for pool locker rooms. The purpose of the experimental work is to design a set of colored plastic furniture for changing the pool to increase the comfortable stay of mother and baby. The development was carried out taking into account the capabilities of the material to create a convenient, safe undressing zone. The study showed that the existing furniture filling of the locker rooms of the pool for mothers with an infant is not fully equipped or does not meet the important requirements for furniture. The experimental work was carried out in three stages, at the first - a sociological study was carried out, at the second - functional ergonomic research, design features and furniture requirements and criteria for evaluating equipment for pools were determined, and on the third - a design proposal for a pool furniture set made of colored plastic was developed. Reviews of employees, managers and visitors to the pools indicate the need for this kit in modern pools in Russia.
