Need a better way to sit for long periods without feeling sore? The Sedens 500 Alternating Pressure Seat Cushion by Wellell helps reduce pressure from sitting too long by slowly shifting your weight. It’s lightweight, easy to carry, and fits most chairs and wheelchairs. The solid foam base with thigh support keeps you steady and well-positioned.

Powered by a built-in lithium-ion battery, it runs for up to 12 hours on a single charge. Visual and sound alerts help keep you safe. With six size options and a 264 lb weight capacity, it’s a great choice for anyone who needs better support while sitting throughout the day.

Battery-Operated Wheelchair Cushion for Daily Use

The Pressure Relieving Seat Cushion is a lightweight, battery-powered wheelchair cushion designed to provide support for individuals who sit for extended periods. Ideal for both wheelchairs and standard chairs, it’s easy to carry with the included adjustable strap and carry bag.

Visual and audible alarms notify users of low battery and low pressure, enhancing safety. With its user-friendly interface and customizable weight settings, this portable seat cushion is built for convenience and reliability.

Alternating Pressure Relief Cushion with Static Therapy

Engineered to help prevent pressure sores and improve blood circulation, this alternating pressure cushion offers five air pressure levels and three timing cycles to promote consistent pressure redistribution. The optional static mode helps maintain support during transfers or when repositioning is needed, making it an excellent pressure relief cushion for elderly or immobile users.

Supportive Foam Base for Stability and Safety

Underneath the air system is a solid foam cushion base designed for stability and posture control. It includes medial thigh support to prevent the legs from turning inward, improving pelvic alignment and overall balance. This makes the seat cushion for posture support ideal for daily use in both home and clinical settings.

Breathable Cushion Cover for Moisture Protection

The 4-way stretch top cover enhances breathability and moisture control, reducing the risk of skin irritation and overheating. It allows for optimal body envelopment without sacrificing support, ensuring the cushion contours gently to the user’s shape. This pressure relief wheelchair cushion is also easy to clean, making it suitable for long-term use.
