You can view her full bio here. Having spent nine years as an outpatient physical therapist specializing in Neurological, Geriatric, and Vestibular Physical Therapy, I understand the importance of quality sleep for overall well-being. The AS2’s balanced support and medium-firm feel particularly caught my attention, aligning well with the needs of my patients seeking optimal sleep conditions.When I had the opportunity to test the Amerisleep AS2 mattress for a month, I approached it with a keen awareness of how proper sleep can impact health. The Amerisleep AS2, with its medium-firm feel, aligns perfectly with the needs of my patients. Later, I was also given the chance to review the Amerisleep AS5 Hybrid.I am a mother and wife, and an active individual outside of these roles as well. I know firsthand jut how much that sleep plays a crucial role in our lives. Through my extensive experience in healthcare, I recognize that investing in a mattress that promotes proper spinal alignment and comfortable sleep can contribute significantly to overall health and vitality.As an experienced outpatient physical therapist, my focus is on the critical role of sleep in overall well-being. In this review, I will integrate insights from Dr. Jordan Burns, a chiropractor and certified sleep coach, who brings a unique perspective on spinal alignment and sleep health.WHO IS THE AMERISLEEP AS2 BEST FOR?Back sleepers: With feel that’s gently firm, the AS2’s surface keeps the spine properly aligned in a neutral position.Combo sleepers: The AS2’s firmer feel is well-suited for combo sleepers who prefer to fall asleep on their backs or stomachs, while still being soft enough that it’s not uncomfortable for side sleeping.Stomach sleepers: The AS2 is firm enough to keep the abdomen from sinking into the surface and causing discomfort, yet not so firm that it feels like a hard board.Hot sleepers: The firmer feel of the AS2 resists heat retention more than a softer mattress would, as it hugs the body less and absorbs less heat.Heavier sleepers: The AS2 mattress easily supports a bulkier body without losing its shape or comfort.Suitability of the Amerisleep AS2 mattress for various types of sleepers, as detailed by Dr. Jennifer Miller, PT, DPT.

Claim Deal Unboxing, Setup and First ImpressionsAmerisleep sent me their AS2 model compressed, sealed and wrapped up in a compact, white box. I unboxed it and set it up for testing, and after I freed it from its plastic wrapping the mattress rose before my eyes.The off-gassing smell lingered for a spell, and I give it a 2 out of 5 (with 5 being no smell and 1 being a strong smell). But overall, it was only mildly noticeable for a brief period after the initial setup and didn’t distract me from the comfort potential that the Amerisleep AS2 offered.Dr. Burns, in his video above, remarks on the absence of a significant off-gassing smell, highlighting that this initial smell sensitivity can vary among sleepers. In my case, upon unboxing the Amerisleep AS2, I noticed a mild off-gassing smell, which dissipated fairly quickly. Off-Gassing Odor Score 2 out of 5Durable Mattress Construction for Thorough Comfort and SupportAmerisleep informed me about the construction of its AS2 mattress, and I remembered its details as I took in the mattress’s design. While a firmer bed, the Amerisleep AS2 features a plush and breathable cover crafted from a unique fiber blend that shares qualities with Celliant, which a material known for its exceptional energy transfer properties. Their Refresh cover fabrics works extra hard to ensure you stay cool at night, a necessity for hot summer nights.Directly beneath lies a remarkable 2-inch layer of Bio-Pur memory foam, skillfully designed to cradle pressure points while maintaining its resilient nature. Amerisleep’s innovative approach has truly transformed traditional memory foam, giving it a stay-cool bounce I appreciated.Adding to this, a 3-inch Affinity transition layer is thoughtfully zoned, incorporating softer foam beneath the shoulders and sturdier foam under the hips. This zoning played a crucial role in maintaining the alignment of my spine during sleep. Lastly, the substantial 7-inch base foam provides robust reinforcement to the entire mattress, ensuring its lasting stability and unwavering support night after night.I stretched out and gave the mattress a thorough test drive during its first month, sleeping and lounging about on it. I was impressed by the mattress’s durability, watching the surface snap back into place within seconds of me moving across it or pressing a hand down. Durability Score 5 out of 5Comfort, Support and Firmness for that Great FeelAs a mattress built to be firm but not too much, the AS2 impressed me with its feel, and I give it a 4 out of 5 stars for firmness. Not the hardest bed around, but few want to sleep on a rock and the AS2 has that needed bit of give for the torso to lightly sink in. I would say the firmness is more firm than medium. Just what you want without too much soft cushion.Now, I’m a regular side sleeper, but the AS2 is a model built for back and stomach sleepers. This model is overall not quite the right fit for me, but I could see if I was the type to drift off on my back it would be supportive and just conforming enough to mold to my back’s muscles and spine. Still, I was surprised by how comfy a mattress not quite suited to my sleep style felt, leading me to giving it a 4 out of 5 for support and comfort. Firmness Score 4 out of 5 Support & Comfort Score 4 out of 5Moving About and Lying Down for Pressure ReliefI tested the Amerisleep AS2 in my preferred side sleeping position, and even though the mattress was a touch too firm for my tastes, I was still impressed by the pressure relief the bed offered. It did a good job of hugging my shoulders and hips so I wasn’t too uncomfortable, and I give it a 3 out of 5 since I didn’t wake up with major aches and pains.Moving about on the AS2 was a simple enough matter. It wasn’t a mattress that unnecessarily gave way as I tried to move, trapping me with a surface too slow to react to my movements. However, its foamy structure still isn’t the easiest to move about on, simply due to its material construction. So I give it a 4 out of 5 for its ease of movement.However, the AS2 thoroughly impressed me with its motion isolation capabilities. It adapted quickly, swallowing my movements so that anyone lying down with me wouldn’t stir and wake up. I give this aspect of the AS2 a 5 out of 5 score, and would recommend it to people who intend on sharing a couples’ mattress.I was also quite pleased with the edge support that the AS2 offered. I could sit on the edge comfortably, letting my feet rest on the floor, and it was easy to just put my hands down on the side and push myself out of bed. I can see this feature being a big help for my patients who have stiffness or debilitating pain in the morning, and I give the AS2’s edge score a 5 out of 5. Pressure Relief Score 3 out of 5 Edge Support Score 5 out of 5 Ease of Movement Score 4 out of 5 Motion Isolation Score 5 out of 5Beating the Heat & Staying Cool at NightThe AS2 is quick to feel cool as I lie down, and I give it a 5 out of 5 for its temperature-neutral feel as I stretched out. Its feel was gently icy, more like sinking into a cool bath than a cold slab of foam.Having just experienced one of the hottest summers on record, it was important for this mattress to stay cool for me as I slept, and the AS2 succeeded quite well at that, helping me to sleep without interruptions or any icky sweating. I am giving it a 2 out of 5 as my sleep temperature score (measuring if I stayed cool overnight or slept hot, 1 being cool, 5 being hot). Temperature Neutrality Score 5 out of 5 Temperature Maintenance Score 2 out of 5Affordable Firmer ComfortThese days I know money is tight for a lot of my patients, just as it is for many others. Buying a new mattress can be a big step for many, and it helps to know that what you’re getting is reasonably priced with high expected value. Drawing upon what I have seen of the AS2’s durability, I can say it met and exceeded my expectations for its value.Amerisleep AS2 Mattress Sizes and PricesAmerisleep AS2 SizeDimensionsSales PriceTwin Size38 inches wide by 74 inches long by 12 inches tall$849Twin XL Size38 inches wide by 80 inches long by 12 inches tall$899Full Size54 inches wide by 75 inches long by 12 inches tall$1049Queen Size60 inches wide by 80 inches long by 12 inches tall$1099King Size76 inches wide by 80 inches long by 12 inches tall$1399California King Size72 inches wide by 84 inches long by 12 inches tall$1399Split King SizeTwo mattresses 38 inches wide by 80 inches long by 12 inches tall$1798What Other Customers ThoughtObviously, I’m not the first person to sleep on the AS2 mattress and I wanted to see what other people who were satisfied customers thought of the experience.
