Important Aspects When Choosing The Best Memory Foam Mattress Under $800

Firmness Level

Choosing the right firmness depends on your sleep position:

• Soft (Plush) – Best for side sleepers, as it cushions pressure points.
• Medium – Ideal for combination sleepers who need balanced support.
• Firm – Best for back and stomach sleepers, providing spinal support.

Cooling Features

Traditional memory foam retains heat, so modern models include cooling technologies such as:

• Gel-infused foam to absorb and dissipate body heat.
• Open-cell foam for improved airflow.
• Breathable covers to wick away moisture.

Mattress Thickness

Most memory foam mattresses under $800 range from 10 to 14 inches in thickness. Thicker models offer more support and durability, making them ideal for heavier sleepers.

Motion Isolation

Memory foam is excellent at absorbing movement, making it perfect for couples or restless sleepers who don’t want to be disturbed by motion.

Edge Support

Some memory foam mattresses may lack strong edge support, so look for models with reinforced foam layers if you need extra stability.

Tips for Using a Memory Foam Mattress Under $800

• Let it expand fully – Most memory foam mattresses come compressed in a box and need 24-72 hours to reach full size.
• Use a solid foundation – A platform bed or slatted base works best to prevent sagging.
• Rotate it regularly – Memory foam mattresses don’t need flipping, but rotating every 6 months helps maintain even wear.
• Invest in a mattress protector – Protects against spills, dust, and allergens for a longer lifespan.
