The goal of this clinical trial is to evaluate the impact of different sitting environments on general well-being and movement patterns in healthy young adults aged 18-35. The main questions it aims to answer are:

Does floor sitting lead to increased movement and postural changes compared to chair sitting? Over a month-long period, how does sustained floor sitting influence overall well-being, posture, and movement habits?

Researchers will compare the effects of chair sitting and floor sitting in a controlled lab environment (Aim 1) and observe the longer-term effects of habitual floor sitting in participants natural environments (Aim 2) to see if consistent floor sitting promotes more dynamic movement and comfort.

Participants will:

Undergo two 30-minute experimental sitting sessions, one in a chair and the other on the floor, while engaging in typical desk activities (Aim 1).

Participate in a month-long study where they integrate an hour of floor sitting into their daily routines, recording their experiences and any changes in sitting habits through daily diaries and in-depth interview (Aim 2).

Inclusion Criteria:

• age 18-35 years
• English-speaking
• willing and able to complete study procedures.

Exclusion Criteria:

• Any injuries or conditions that would limit participants from sitting on the floor in a safe manner, mental states that would preclude the complete understanding of the protocol and compliance, and prior knowledge of the study hypotheses, as it may potentially influence participant behavior and compromise the integrity of the study.
