Firm Mattresses

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.

I Love This Mattress
My wife has a bad back so we needed a very firm mattress. Our old mattress was sagging and had to go so we bought a very nice split king mattress but it was just not firm enough. We saw Amerisleep and took a chance. No more back pain - we are amazed but love it. Would highly recommend.

Finally, a mattress that's firm enough for me! My back pain has significantly improved since I switched to the AS2.
John S.
I'm a stomach sleeper and have always struggled to find a mattress that provides enough support. The AS1 is perfect! It's firm but still comfortable.
Sarah L.
As a heavier individual, I need a mattress that won't sag. The AS2 is incredibly supportive and durable. I'm sleeping better than ever!
Michael B.
Very satisfied customer
Love the mattress! I have back problems and this mattress is so comfortable. I sleep better and the usual soreness I felt every morning with my previous mattresses has disappeared. We liked the first mattress so much, we bought another for the guest room.

I would definitely buy this product again.
We are both back and side sleepers and the mattress works great for us. This mattress made sleeping with a bad hip before and after hip replacement surgery possible. Our old mattress made sleeping especially on the side intolerable.

Liked the king size so much I bought my daughter one!
I like a firm mattress and shopped in stores for months trying to find the right one for me. None were comfortable. I took a shot with the Amerisleep AS1 after many reviews said it was a firm mattress. Best decision! It was so comfortable that I turned around and bought one for my daughters full size bed.

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.

Is a Firm Mattress Right for You?

Firm mattresses are often recommended for:

  • Back Sleepers

    Provide optimal support to keep the spine aligned in a neutral position.

  • Stomach Sleepers

    Prevent the hips from sinking too deeply, which can strain the lower back.

  • Heavier Individuals (230+ lbs)

    Offer the necessary support to prevent excessive sinking and maintain spinal alignment.

  • Those with Back Pain

    Can help alleviate back pain by providing proper support and reducing pressure points. Dr. Jordan Burns recommends the AS2 for patients with degenerative disc disease and spinal stenosis.

If you're unsure whether a firm mattress is right for you, we encourage you to take our mattress quiz or visit our Scottsdale, Arizona showroom to speak with a sleep expert.

Investing in a Firm Mattress: Value and Affordability

At Amerisleep, we offer a range of firm mattresses to fit different budgets. While firm mattresses may sometimes have a slightly higher upfront cost due to the use of high-density foams and durable support layers, they are a worthwhile investment in your long-term health and well-being.

AS2: Our Chiropractor-Recommended Firm Mattress for Back Pain Relief

The AS2 is our top recommendation for those seeking a firm mattress for back pain relief. It features a medium-firm feel, combining 2 inches of our pressure-relieving Bio-Pur® foam with 3 inches of targeted support from our HIVE® technology and 7 inches of our durable Bio-Core® base.

Chiropractor Dr. Jordan Burns frequently recommends the AS2 to his patients, stating, "The medium-firmness of the AS2 mattress, as well as the five zones of targeted support, make this mattress my top choice for my patients suffering from DDD" and "Studies have shown that firmer mattresses like the Amerisleep AS2 provide pressure-relief support which can help to reduce pain associated with spinal stenosis."

Choosing a Firm Mattress

Watch as Dr. Jordan Burns, a practicing chiropractor, shares his expert tips on reducing back pain while sleeping, including the importance of choosing the right mattress firmness:

Key takeaways from Dr. Burns:

  • Choosing the right mattress firmness is crucial for spinal alignment.
  • Proper pillow support is essential for neck pain relief.
  • Sleeping position can significantly impact back pain.

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.

What is the best firm mattress?

We recommend taking our mattress quiz to discover which firm mattress best suits your needs. You can read more in our best firm mattress blog.

Where can I learn more about choosing a mattress to avoid back pain?

Many charities accept mattress donations. You can also check with your local waste management company for recycling options. We also offer old mattress removal services in select locations. Learn more about mattress donation options here: https://amerisleep.com/blog/mattress-donation/.

Do you have any showrooms where I can try out the mattresses?

Yes, we have a showroom located in Scottsdale, Arizona at the Optima Camelview. We encourage you to visit us and experience the comfort of our mattresses in person. Our knowledgeable sleep experts can answer any questions you have and help you find the perfect mattress for your needs.
