Memory foam, also known as viscoelastic foam, is popular because it relieves pressure while still bouncing back quickly enough to be supportive. Because of its density, memory foam tends to trap heat. Amerisleep offsets this problem by using plant-based Bio-Pur®.
Made with castor oil instead of petrochemicals, it releases minimal off-gassing odors upon opening and circulates air easier than traditional memory foam.

Thanks to the premium quality materials in each of our mattresses, you can sleep comfortably for years to come.
Stretchy, soft cover ensures the top layer stays cool.
Plant-based Bio-Pur® hugs your body and bounces back to its original shape quickly.
The Affinity Layer with HIVE® offers pressure relief and enhanced lumbar support.
The durable Bio-Core® base layer distributes your weight evenly across the sleep surface, ensuring the mattress lasts for the entire length of the warranty.
We absolutely love our AS3! We both had back pains prior to purchasing this bed and can honestly say, after 4 months, we haven't noticed a single ache or pain since. Would purchase again and again!
Lake Charles, LA
I purchased the AS3 mattress 3 months ago, and it has been a lifesaver. My husband and I have back issues, and we needed a bed that would help us get quality sleep. We have always struggled with being able to sleep through the night due to aches and pains and now that we have been sleeping on our AS3 mattress for 3 months now, we finally are able to sleep comfortably through the ENTIRE night!
Sioux Falls, SD
I purchased the AS3 and couldn't be happier, I now own 2! A king size and a king size and I will never buy another brand again. I would definitely recommend the king size AS3 over and over again, if you're considering buying this mattress because you're not getting great sleep or you're simply due for a new mattress... TREAT YOURSELF. I promise you will not regret it.
Westchester County, NY
We've slept on this bed for 9 months now. It's the perfect blend of softness and support. It's so comfortable we have accidentally slept till noon on many occasions! My husband has had knee and shoulder surgery and this bed is comfortable for him to sleep on his side. My back and hip pain from standing at work all day is decreased. My kids are always trying to sneak in to sleep on it. This is the best bed we've ever owned.
We have had our Amerisleep AS4 for about two months now. It is living up to the hype so far. My husband and I both have back problems and needed support plus give in the mattress. The Amerisleep AS4 fits our needs perfectly (for reference purposes, my husband and I are both under 160lbs). In fact, the first night we had our new Amerisleep, my husband slept for 10 hours straight! That has never happened in the 20+ years we've been married!
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 was skeptical of ordering a mattress online even though I was able to test it in the store prior to ordering. The delivery was a breeze and the mattress didn't even need to off-gas, but it's the sound sleep provided that is the point of this review. I sleep on my back now and haven't in years. Who knew I was a back sleeper? This mattress (A2) is firm and supportive yet still soft and cozy and has provided the best sleep I've ever had. Thanks for making me excited about bed again!
This is an excellent mattress. I was a bit worried about getting the AS2, as I am primarily a side sleeper, but I am getting the best sleep of my life whether I am on my side or my back. The best part is how sturdy yet quiet the bed is. My partner and I go to sleep and wake up at different times, and neither of us notice when the other gets in/out of bed. I also run pretty hot, and in my previous bed was no stranger to waking up sweaty, but this mattress keeps me cool and dry.
The AS2's firmness is exactly as explained— firmer than the middle-ground AS3 but not super firm which is exactly what my fiancé and I wanted. We really liked knowing that we could exchange it within 100 days if we needed to but we sleep very well on this mattress and intend to keep it for a long long time.
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.
I have always had back issues waking up and difficulties getting to sleep on my current mattress and previous ones but when my new mattress was delivered I noticed a difference the first night! I now look forward to using it and sleep like a rock.
This is my first memory foam mattress. I have always had a pillow top. I was afraid to order the wrong type for my body/sleep type. I spoke with customer service and was recommended the AS5 since birth my husband and I are smaller people (I'm 112 pounds and 5'2 and my husband is 5'8 and 165 pounds), and we both are side sleepers primarily (I also sleep on my back). I was worried it would be too soft or not soft enough, but it is perfect.
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.
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.
My wife and I use this bed every single night now. We chose the firm model in hopes we would wake up with less aches and pains after a night of sleep. It’s done that and more! Super comfortable bed while being extremely sturdy. Can’t believe how easy and fast the purchasing process was either. I would highly recommend this bed to anyone and everyone. What are you waiting for??
I just got married and my wife wanted. A different bed. I already had the AS2 which is more firm, but she wanted a softer one. I sleep on my back and side so the AS3 worked best for both of us.

A king-size bed is wider and shorter, measuring at 76” by 80”, while a California king size mattress is longer and more narrow at 72” by 84”.
Also known as a “western king” California king size mattresses were created in California to accommodate larger living areas, and have since grown in popularity.
It depends on what you value more—length or width. California king size mattresses are better-suited for sleepers over 6-feet-tall who need the additional legroom. Standard king mattresses are best for couples who prefer extra personal space to get comfortable.
The best California king size mattress should relieve pressure points, especially in heavier sections of the body, evenly support weight, and last at least 7 to 9 years. You can determine the best mattress for your sleep needs by considering your sleeping position and body weight—a mattress should be soft enough to alleviate pressure and firm enough to facilitate proper spinal alignment no matter how you sleep.
Choose mattress firmness based on your body weight and preferred sleep position for pressure point relief and consistent spinal alignment. For example, sleepers over 230 pounds will find themselves most comfortable on firmer mattresses since these beds don’t allow for much sinkage. On the other hand, petite sleepers will like softer beds better because they offer enhanced cushioning comfort.
Each of our mattresses come with a 100-night sleep trial, a 20-year warranty, free shipping, and free returns. If you decide during your sleep trial that the mattress isn’t right for you, just give us a call, and we’ll arrange for it to be picked up free of charge and will issue a full refund.
We offer eight mattress models: five memory foam mattresses and three hybrids—our California king size mattresses range in price from $1199 to $1749.
Our mattresses feature innovative pressure-relieving Bio-Pur® to alleviate aches and pains and prevent future discomfort. Bio-Pur® molds to the body to offer immediate cushioning comfort and relieve tension in throughout your body, especially in the back, shoulders, and hips.
Each of our mattresses (besides the hybrids and AS1) also features HIVE® technology, HIVE® offers zoned support to promote healthy spinal alignment and prevent backaches. HIVE® offers firm support under your torso, head, and feet to maintain healthy alignment and is softer under the shoulders and hips for improved pressure relief.
If you’re looking for the best mattress for back pain, consider our AS2, as it was previously voted by Business Insider as one of the best mattresses for back pain relief.
Memory foam mattresses, on average, last about 7 to 10 years, whereas hybrid mattresses last 6 to 9 years, usually. We build our mattresses with highly-durable materials to help you get the most for your money. Plus, we offer a 20-year warranty with each of our beds, protecting you from manufacturing defects and sags.
Each mattress comes with a 20-year warranty, covering sagging greater than 0.75” and any manufacturing defects causing damage to the mattress.
