The McKesson Convoluted Foam Mattress Overlay is a simple, cost-effective pressure relief solution designed to improve comfort and promote airflow for individuals who spend extended time in bed. Featuring an egg crate (convoluted) foam design, this overlay helps distribute body weight evenly while reducing pressure on sensitive areas.

Ideal for home care, recovery, or short-term use, this lightweight overlay sits directly on top of an existing mattress to provide added cushioning without the complexity of powered systems.

What is a Convoluted Foam Mattress Overlay?

A convoluted foam mattress overlay, often called an “egg crate” overlay, uses a textured foam surface to improve airflow and help redistribute pressure. It is a non-powered solution designed primarily for comfort and basic pressure relief.

Quick Summary

• Non-powered foam mattress overlay
• Egg crate design improves airflow and comfort
• Helps distribute body weight to reduce pressure points
• Lightweight and easy to position
• Great for short-term use or budget-friendly care setups

Why Choose the McKesson Foam Overlay?

This overlay is ideal for users who need a basic level of pressure redistribution without investing in gel, air, or powered systems. The convoluted foam design increases surface area contact, helping reduce pressure while promoting air circulation for a cooler sleeping surface.

It is especially useful for:

• Short-term recovery after surgery
• Occasional bed use or temporary care
• Budget-conscious setups
• Layering with other support surfaces

While effective for comfort, this type of overlay is generally considered a lower-level solution compared to gel, air, or alternating pressure systems.
