Abstract

La présente invention se rapporte à un coussin fonctionnel à ressorts. Le coussin fonctionnel à ressorts selon la présente invention est fabriqué de telle façon que les caractéristiques des ressorts, y compris leur hauteur, leur dimension et leur module d'élasticité, sont ajustées en fonction des emplacements des ressorts. Ainsi, le coussin de la présente invention empêche que le bassin d'un utilisateur soit en contact direct avec le sol afin d'améliorer la ventilation et assurer le confort de l'utilisateur. Les ressorts du coussin de la présente invention distribuent de manière efficace le poids de l'utilisateur pour réduire efficacement les douleurs et supportent le bassin et les cuisses de l'utilisateur afin que celui-ci conserve une posture correcte. De plus, selon la présente invention, la surface supérieure du revêtement est constituée d'une maille aérée d'une extrême perméabilité à l'air, améliorant ainsi la perméabilité à l'air du coussin et assurant à l'utilisateur confort et douceur.
