Weelko SPONG Flat-Base Physiotherapy Positioning Half Bolster

SPONG Half-Round Bolster: Stable Low-Level Elevation

There are two reasons to choose a half-round bolster instead of a full-round bolster. The first is height: sometimes you only need slight elevation to relieve tension on a joint without causing compensatory movement. The second, particularly useful in daily professional practice, is that a half-round bolster has a flat base and does not roll. Once positioned, it stays in place when the patient readjusts or when you mobilise the body segment.

SPONG is the half-round positioning bolster in the Weelko range. It features medium-density foam, a washable cover and a weight of just 0.4 kg, making it the easiest accessory to handle on the service trolley.

Technical Specifications

When to Use the Half-Round Bolster

• Gentle cervical support. Maintains the natural curve of the neck without causing flexion, ideal for trapezius and suboccipital treatment.
• Under the ankles in the prone position. Provides sufficient minimal elevation to help prevent knee hyperextension.
• Under the knee for patients with limited mobility. Suitable when a full-round bolster places excessive tension on the hamstrings.
• Wrist and forearm support. For upper-limb treatments performed with the patient seated.
• Lateral stabilisation. Used as a support wedge in the side-lying position.

SPONG or PLUM

The SPONG provides less elevation but remains stable. The PLUM, a full-round bolster, provides maximum elevation but may roll unless held in place by the patient's weight. They are not competing products: they cover different height ranges and are often used together in professional physiotherapy practices where patient positioning is a priority. If you only require one and work without an assistant, the half-round bolster is easier to manage.

Maintenance

Clean with a damp cloth, neutral detergent and a healthcare-grade surface disinfectant between patients. Avoid high concentrations of alcohol. Store it resting on its flat base with no weight on top so that the foam retains its shape.
