Why you need this foot rest - Improves posture and comfort during long periods of sitting by supporting your feet and raising the lower-body center of gravity. - Reduces pressure on thighs and helps keep your back straight, easing lower-back stress and fatigue so you feel more comfortable and productive. - Adds simple ergonomic support to any under-desk workspace without changing your chair or desk. Key benefits and features - Six adjustable heights: 3.5", 4.3", 5.1", 5.9", 6.7", 7.5" — choose the best height for your body, chair, and desk. - Easy adjustment: turn the screws on both sides to set and lock the height quickly and securely. - Ergonomic design: raises and supports your feet to promote correct sitting posture and reduce pressure on your thighs. - Dual massage surfaces: a large area with small particle massage texture plus four large massage rollers — alternate surfaces to soothe feet, promote circulation, and help legs relax. - Stable and durable construction: designed for stability and long-term use; includes non-slip pads on the four legs to keep the foot rest in place. - Low maintenance: will not warp or collapse like memory foam pads and is easier to clean than memory foam. - Color: black — neutral and suitable for most office and home settings. How it solves common problems - Slumped posture and lower-back discomfort: by supporting the feet and adjusting height, it helps you maintain an upright spine and reduces load on the lower back. - Leg fatigue and poor circulation: rolling the massage rollers or using the textured surface stimulates the soles of the feet and improves blood flow. - Unstable or messy foot supports: non-slip leg pads keep the unit steady; the solid construction avoids sagging or deformation over time. Simple operation - Place the foot rest under your desk. - Turn the screws on both sides to raise or lower the platform to one of six height positions. - Use the textured surface or roll your feet over the four massage rollers as needed. Practical use scenarios - Office workstation: keep the foot rest under a desk to support feet during long workdays and reduce back fatigue. - Home computer or study area: adjust height for different chairs or shared workspaces so every user can sit comfortably. - Remote meetings and focused tasks: use the massage rollers between tasks to relieve tension and improve circulation without leaving your desk. What to expect - A stable, adjustable under-desk foot rest that improves posture and comfort. - Quick height changes using side screws and two massage options for added relief. - Durable performance with non-slip feet and easier cleaning compared with memory foam alternatives.
