Important Aspects When Choosing The Best Mattress Under $400
Firmness Level
Your sleep position plays a major role in choosing the right firmness level:
- Soft (Plush) – Best for side sleepers, as it cushions shoulders and hips.
- Medium – Ideal for combination sleepers who need balanced support.
- Firm – Best for back and stomach sleepers, keeping the spine aligned.
Mattress Size
Many mattresses under $400 come in various sizes:
- Twin/Twin XL – Ideal for kids, teens, and smaller spaces.
- Full – Great for single sleepers needing more space.
- Queen – The most popular size for couples and single adults.
- King – Available in some models but harder to find in this price range.
Cooling Features
If you sleep hot, look for:
- Gel-infused memory foam to absorb heat.
- Breathable covers for moisture control.
- Hybrid models with coils for improved airflow.
Motion Isolation
If you share a bed, motion isolation is key. Memory foam and hybrid mattresses help absorb movement so you won’t disturb your partner.
Durability and Warranty
A good mattress in this price range should last 5-8 years. Look for brands that offer at least a 10-year warranty.
Tips for Using a Mattress Under $400
- Allow full expansion – Many mattresses are compressed in a box and need 24-72 hours to fully expand.
- Use a supportive base – A platform bed or box spring helps prevent sagging.
- Rotate it regularly – Rotating every 3-6 months promotes even wear.
- Consider a mattress topper – If it feels too firm, a foam topper can add extra comfort.
