In Nu assis sur un tabouret, a seated nude figure dominates the canvas. The colors are bold and vibrant, with a strong contrast between warm and cool tones. The figure's posture is relaxed, yet it exudes a sense of confidence.

The background is simplified, allowing the viewer to focus on the figure's form and colors. The painting is characterized by Matisse's signature use of color and form. The brushwork is loose and expressive, contributing to the overall sense of movement. The composition is balanced, with the figure placed centrally against a contrasting background.

This work exemplifies Matisse's exploration of the human form and color relationships. Henri Matisse was a leading figure in the Fauvist movement, known for his use of color as a means of expression. Nu assis sur un tabouret reflects his interest in the nude as a subject, which he explored throughout his career. An interesting fact about this work is that it showcases Matisse's transition towards a more simplified and abstract style.

This painting is part of the collection at the Musée d'Orsay in Paris.
