Questions We Get a Lot
An SL-track follows the natural curve of your spine from neck all the way down through the glutes and upper hamstrings, offering more comprehensive coverage than a standard L-track. Our SL-track chairs are designed to support full spinal length massage, making them a strong choice for anyone who spends long hours sitting or experiences tension across the lower back and hips.
4D refers to the roller mechanism's ability to move in four dimensions: up and down, side to side, in and out, and with variable speed and intensity mid-massage. This allows the chair to more closely mimic the feel of human hands, adjusting depth and rhythm in a way that earlier 2D and 3D systems could not. If you want a massage experience that feels responsive rather than mechanical, 4D is worth considering.
Zero gravity positioning reclines the chair so your legs are elevated roughly level with your heart, which shifts your body weight distribution and reduces pressure on the spine during a session. Many users find it meaningfully more comfortable than a standard recline, especially for lower back tension. All zero gravity chairs in our collection are designed to reach this position automatically at the start of a session.
We offer 30-Day Returns on massage chairs purchased through Pure Sleep Optimization. If you find the chair is not the right fit, please refer to our Return Policy page for the full process and eligibility details. We recommend reaching out to our team early so we can help find the best resolution for your situation.
