Memory�Foam�Technology�Explained:

How�Memory�Foam�Works

Memory�foam,�technically�known�as�viscoelastic�polyurethane�foam,�responds�to�body�heat�and�pressure�by�softening�and conforming to your body shape. This creates a custom sleeping surface that:

• Distributes weight evenly across the mattress
• Eliminates pressure points that cause discomfort
• Returns�to�original�shape�when�pressure�is�removed
• Provides excellent motion isolation

Types�of�Memory�Foam:

Traditional�Memory�Foam

• Slow�response�time�(3-5�seconds)
• Excellent pressure relief
• Retains body heat
• Budget-friendly�option

Gel-Infused�Memory�Foam

• Enhanced�cooling�properties
• Faster response time
• Maintains�pressure�relief�benefits
• Mid-range pricing

Plant-Based�Memory�Foam

• More�responsive�than�traditional�foam
• Better temperature regulation
• Eco-friendly�manufacturing
• Premium pricing

Copper-Infused�Memory�Foam

• Natural antimicrobial properties�
• Enhanced�cooling�and�conductivity
• Improved durability
• Luxury�segment
