Spuka OrthoBase

Ergonomic Lumbar Support to Eliminate the Lower Back Gap

Standard flat chairs fail to support the natural S-curve of your spine, leaving a critical lower-back gap that forces spinal discs to strain and collapse under pressure. Spuka fills this gap with targeted ergonomic lumbar contouring that cradles your lower back and promotes healthy, upright posture. By replacing flat, rigid chair backs with supportive pressure-relieving foam, it prevents slouching, eases disc compression, and turns office chairs, car seats, or dining chairs into orthopedic-style seating for long hours of pain-free sitting.

• Targeted Lumbar Support: Fills the painful lower-back gap to keep your spine in natural, healthy alignment.

• Disc Pressure Relief: Counteracts spinal strain caused by flat backrests, protecting discs during long sitting sessions.

• Postural Alignment: Encourages upright sitting posture to reduce fatigue across your back, shoulders, and neck.

Tailbone Weight Offloading & Non-Slip Portable Design

Flat seats concentrate your entire body weight straight into your tailbone and pelvic base, leading to sharp pressure points and soreness. Spuka utilizes high-density orthopedic memory foam to absorb and evenly distribute body weight, taking direct pressure off the coccyx and hip joints. Complete with a non-slip rubber base that locks securely onto any seat, a removable machine-washable cover, and a lightweight build, it delivers clean, secure, and portable comfort wherever you sit, drive, or travel.

• Tailbone Pressure Redistribution: Cushions the coccyx to prevent painful weight concentration on hard, flat surfaces.

• Non-Slip Secure Base: High-grip bottom keeps the cushion firmly anchored to your seat without sliding or shifting.

• Portable & Easy Maintenance: Lightweight design features a removable, machine-washable cover for clean, everyday travel.
