Wellell Domus 1 Alternating Bubble System

Introduction

The Wellell Domus 1 Alternating Bubble System is a specialized alternating pressure mattress overlay designed to prevent and treat early-stage pressure ulcers (bedsores). Its lightweight, compact design makes it an ideal solution for patients at low to moderate risk of pressure injury, particularly those who are bedridden or have limited mobility. The system works by alternating air pressure within its bubble cells to redistribute pressure evenly across the body, reducing the risk of tissue damage.

Key benefits of the Domus 1 system include easy setup over existing mattresses, quiet operation, and portability, making it well-suited for home care, long-term care, and transitional care settings. Its medical-grade materials ensure hygiene and durability, while the adjustable pressure pump allows caregivers to tailor comfort and therapeutic effect. With an estimated price range of around $90 to $220, depending on the retailer and package, the Domus 1 offers an affordable yet effective pressure relief solution that competes well with heavier, bulkier alternatives.

This system targets caregivers and healthcare professionals managing patients with early pressure injuries, as well as family members seeking reliable, user-friendly pressure care at home. It is especially useful for individuals with body weights up to 220 pounds and those needing a compact, easy-to-handle mattress overlay that does not require relocating the patient during therapy.
