Yoga Block Master Kostka MASTER Green 23 x 15 x 7.5 cm — foam support for yoga and stretching

Master Kostka MASTER Green is a foam yoga block measuring 23 x 15 x 7.5 cm that provides stable, lightweight support for yoga, pilates and stretching exercises. Designed to assist alignment and extend reach, this foam support helps both beginners and experienced practitioners modify poses, maintain balance and reduce strain during seated, standing and floor-based movements. Its compact size and low weight make it suitable for studio classes, home practice and travel.

Advantages

The foam construction offers firm yet slightly forgiving support that cushions joints while maintaining stability. The block's rectangular shape and flat surfaces enable reliable placement under hands, feet or hips to improve posture and alignment. Its compact dimensions make it easy to carry and store, and the closed-cell foam resists moisture and is simple to wipe clean after sessions.

Suitable for

• Beginners learning pose alignment and balance
• Practitioners adapting poses to increase comfort or reach
• Pilates and stretching routines that require stable elevation or support
• Home workouts and studio classes where portable props are needed

Key specifications

• Material: closed-cell foam providing firm, supportive feel
• Dimensions: 23 x 15 x 7.5 cm
• Weight: lightweight and portable for easy handling
• Surface: flat faces for stable placement in multiple orientations
• Care: wipe-clean surface resistant to moisture and sweat

How to use

Place the foam block under hands, feet, hips or head to modify the height and alignment of poses. Use the block lengthwise, crosswise or on its thicker edge depending on the required elevation: the 7.5 cm thickness provides higher support while laying the block on its 15 cm or 23 cm faces reduces height. For restorative poses, position the block to support the lower back or neck; for standing balances, use it beneath the hands to reduce the distance to the ground. After use, wipe the block with a damp cloth and allow to air dry.

Usage recommendations

The Master Kostka foam block is intended as a supportive prop to enhance alignment and comfort; check stability before applying full weight and replace the block if it shows excessive wear or deformation.
