A better firm mattress for all sleepers
Why Choose a Firm Mattress?
Firm mattresses provide optimal support for back and stomach sleepers, helping to maintain proper spinal alignment throughout the night. They offer a solid sleep surface that prevents excessive sinking, which can lead to back pain and discomfort. Our firm mattresses are also a great choice for heavier individuals who need extra support.
Dr. Jordan Burns, a chiropractor, explains that research has shown that firmer mattresses, like the Amerisleep AS2, provide pressure-relief support to help to reduce pain and keep your spine in a neutral alignment.

Experience the Benefits of a Firm Mattress
- Optimal Spinal Alignment: Firm mattresses help maintain proper spinal alignment, especially for back and stomach sleepers. They prevent excessive sinking, which can cause the spine to curve unnaturally, leading to pain and discomfort.
- Superior Support: Our firm mattresses provide a solid and supportive sleep surface, distributing weight evenly and reducing pressure points. This is particularly beneficial for heavier individuals who need extra support.
- Long-Lasting Durability: We use high-density foams, like our Bio-Core® base layer, to ensure that our firm mattresses resist sagging and maintain their supportive properties for years to come.
- Pain Relief: Many customers, especially those with back pain, find that a firm mattress provides significant pain relief. As Dr. Jordan Burns notes, "firmer mattresses, like the Amerisleep AS2, provide pressure-relief support to help to reduce pain and keep your spine in a neutral alignment".


The Science Behind Our Firm Support
- Bio-Pur®: Our plant-based memory foam, featured in all our mattresses, conforms to your body even in our firm models, providing pressure relief while maintaining a supportive feel.
- HIVE® Technology: Featured in our AS2 model, HIVE® technology provides targeted support with five distinct zones, ensuring optimal spinal alignment.
- Bio-Core®: Our firm mattresses rely on a high-density Bio-Core® support layer. This durable base prevents sagging and ensures long-lasting support, making our firm mattresses an excellent investment in your sleep health.

Frequently Asked Questions
Will a firm mattress help back pain or cause discomfort for side sleepers?
A firm mattress can be beneficial for back pain, especially for back and stomach sleepers. However, side sleepers generally need a softer mattress to cushion their shoulders and hips. If you're a side sleeper with back pain, a medium-firm mattress with good pressure relief, like our AS3, might be a better option. You can also learn more about choosing the right mattress firmness.
How does Bio-Pur® foam adapt in a firm model?
Even in our firm models, Bio-Pur® foam still conforms to your body, providing pressure relief while maintaining a supportive feel. The density and thickness of the Bio-Core® support layer are what primarily determine the firmness level.
What's the difference between a firm and an extra-firm mattress?
An extra-firm mattress offers minimal give and feels very solid. A firm mattress provides a balance of support and cushioning, with slightly more give than an extra-firm model.
