Earthlite Three Quarter Round Massage Bolster: Positioning and Biomechanical Benefits
The Earthlite Three Quarter Round Massage Bolster is a specialized positioning tool designed for clinical settings. Its half-cylinder shape with a flat base provides reliable stability and targeted support. As a bolster in Earthlite's range of massage accessories, this product is ideal for supporting the knees, ankles, and cervical region during treatment to reduce muscular tension and spinal strain. Investing in this bolster promotes better patient alignment, aiding muscle relaxation and improving session efficiency.
Using this bolster under the knees while clients lie supine decreases lumbar lordosis and unloads lower back muscles, a crucial element in managing lumbar discomfort. When placed beneath the ankles in a prone position, it assists in relaxing hamstrings and gastrocnemius by facilitating controlled ankle dorsiflexion, which reduces tension prior to deep tissue work. Supporting the neck in proper alignment reduces cervical muscle fatigue, extending patient comfort and improving treatment outcomes.

Structural Core and Upholstery Performance
This bolster features a high-density, supportive foam core engineered to maintain shape through repeated clinical use. It withstands sustained pressure without prematurely compressing, preserving both client comfort and alignment precision. The Comfort-Flex upholstery consists of 100% polyurethane vinyl with a rayon backing, formulated for long-lasting resilience and resistance to common irritants such as oils, water, and disinfectants.
From a hygiene standpoint, this material tolerates commercial spa-grade cleaning protocols without cracking or peeling over a multi-year lifespan. Its surface resists staining and fading, ensuring the bolster remains suitable for professional environments where stringent sanitation is mandatory.
Target Audience
Ideal for high-volume sports massage practices, physical therapy clinics, and independent bodyworkers requiring exceptionally durable, resilient positioning tools that optimize client alignment and pelvic downregulation.

Fit and Maintenance Guidelines
The Earthlite Three Quarter Round Bolster integrates smoothly with standard massage tables, its flat base preventing unwanted movement. The integrated carry handle simplifies transportation between treatment rooms without compromising stability during use. Upholstery resists oils and creams typically applied during sessions.
Cleaning is straightforward: use mild soap and warm water or a clinical surface disinfectant free from alcohol and harsh chemicals. Avoid saturating seams and steer clear of solvents that dry out vinyl. With proper care, this bolster resists cracking and maintains performance through rigorous sanitation cycles.
Frequently Asked Questions
Will this bolster flatten out over time under heavy client weight?
No. Engineered with high-density, professional-grade foam cores, this cushion is structurally built to maintain its original loft and rebound resilience day after day, avoiding the compression failures common in retail foam alternatives.
How do I properly clean and sanitize this cushion between sessions?
Wipe the surface down immediately between clients using a mild soap and warm water solution, or a gentle, alcohol-free disinfectant wipe. Avoid saturating the seams or using harsh chemical solvents, which can dry out the vinyl and lead to premature cracking.
Does this specific shape help with lower back discomfort?
By elevating the knees while the client is supine, or supporting the ankles while prone, this cushion immediately reduces stress on the lumbar spine and hamstrings. This passive structural support triggers profound muscular release, making deep tissue work far more effective.
Shipping Information
Most supplies, accessories, and on-the-shelf items typically are shipped out within 1 to 2 business days, barring unforeseen backorders. If you’ve also ordered items that are "built to order" such as some customized tables they typically ship from the manufacturer's warehouse within 7 to 14 business days or longer for larger stationary or lift tables. If you’ve ordered multiple items from multiple brands then you’ll probably receive multiple box shipments that arrive on different days. Weather and backorders will increase these estimates.
