Important Aspects When Choosing The Best Innerspring Mattress Under $400

Firmness Level

Your sleep position affects which firmness level is best for you:

  • Side sleepers: A medium or plush mattress offers better pressure relief.
  • Back sleepers: A medium-firm option provides proper spinal alignment.
  • Stomach sleepers: A firm mattress helps keep the spine in a neutral position.

Coil Count and Type

A higher coil count generally means better support and durability. Look for at least 500 coils for a full-size mattress and 600+ coils for a queen. Pocketed coils help with motion isolation, while traditional coils offer firmer support.

Edge Support

A mattress with reinforced edges prevents sagging and makes it easier to sit or sleep near the sides. If you need a larger sleep surface, look for mattresses with strong edge support.

Motion Isolation

If you share your bed, a pocketed coil mattress reduces motion transfer, making it less likely to disturb your partner. Traditional innerspring models may not be as effective at absorbing movement.

Cooling Features

Innerspring mattresses naturally have good airflow, but some models add gel-infused foams or breathable covers to stay even cooler. If you overheat at night, look for cooling features.

Tips for Using an Innerspring Mattress Under $400

To get the most comfort and durability from your budget-friendly innerspring mattress, follow these simple tips:

  • Use a supportive bed frame – A strong foundation or box spring helps prevent sagging and extends mattress life.
  • Rotate the mattress regularly – Flipping may not be needed, but rotating your mattress every 3-6 months can prevent uneven wear.
  • Pair with a mattress topper – If you prefer a softer feel, a foam or pillow-top topper can add extra comfort.
  • Protect with a mattress cover – A waterproof or dustproof cover keeps your mattress clean and extends its lifespan.
  • Let it fully expand – Some mattresses arrive compressed. Allow 24-48 hours for full expansion before sleeping on it.

Popular Questions About Innerspring Mattresses

Is an innerspring mattress good for back pain?

Yes! A medium-firm innerspring mattress with good support can help maintain proper spinal alignment, which is important for back pain relief.

Do innerspring mattresses last long?

With proper care, a good innerspring mattress can last 6-8 years. Higher-quality models with strong coils and durable materials may last even longer.

Can I use an innerspring mattress on a platform bed?

Yes, but make sure the platform has slats close together (no more than 3 inches apart) or a solid base to prevent sagging.

What’s better: innerspring or memory foam?

It depends on your preference. Innerspring mattresses offer firm support, better airflow, and more bounce, while memory foam mattresses provide pressure relief and motion isolation. Some people prefer a hybrid mattress, which combines both.

With so many affordable innerspring mattresses under $400, you don’t have to sacrifice comfort for price. Whether you want a firm traditional model or a plush pillow-top, there’s a great option to fit your budget and sleep style.
