Firmness Info

The AS4 is our medium-soft mattress. It offers plush comfort with targeted support that helps you sleep your best. Plus it stays cool all night, making it our most popular model with side sleepers.

We make one model of mattress that is designed to be universally comfortable and medium firm, in order to benefit all different types of sleepers regardless of factors such as age, height, weight, or the way you sleep. We like to describe it as firm enough to be supportive, yet soft enough to be comfortable!
We've designed our foam to work with those who like soft mattresses as well as those who like firm, so we encourage everyone to give us a try regardless of your usual preference. If you're not 100% satisfied, you can return it for a full refund.

Mattress Construction

Materials Overview

Three layer construction:

  • Bio-Pur® foam
  • HIVE® transition layer
  • Bio-Core® foam support layer
  • Refresh Cooling Cover.

Two-layer blended foam designed by and proprietary to Tuft & Needle:

  • The comfort foam layer is 3" of a very high-density foam that we created to achieve our universally comfortable, cool and responsive properties. The density is about 2.8 lbs/cubic ft.
  • The support foam layer is 7" of a high-density poly-foam. The density is about 1.8 lbs/cubic ft.

Comfort Info

Traditional memory foam is made from dense material, so it traps your body heat and can make you sweaty and uncomfortable while you're in bed - and who can sleep like that?
We developed our foam with an enhanced "open cell structure", which means there is more air space between the foam particles. That space wicks away heat while you sleep, and can keep you cooler and more comfortable.

Our foam works in three ways to draw heat from your body and disperse it out of the mattress.
Heat Wicking
Heat is drawn into the mattress where gel and graphite work together to disperse heat outward and away from your body.
Breathable
With the help of our fabric, air flows through the foam cells to boost the speed of heat transfer through the mattress.
No More Quicksand
Our support layer helps hold you closer to the surface to avoid the oven effect caused by sinking in too deeply.

Support Info

Our Bio-Core® foam support layer won't sag even after decades of use. And, like our Bio-Pur® foam, it's partially made from plants instead of petroleum so it's eco-friendly.
The HIVE® layer features hundreds of foam hexagons grouped into five comfort zones. Each zone is designed to provide extra cushion where you want it and support where you need it. That way your body gets the support it needs to stay properly aligned, so you can sleep your best.

Designed to be one type of comfort, we are continuously tweaking the mattress to be universally comfortable for everyone. Our foam supports the natural posture of your spine, relieves back, shoulder, and neck pain and naturally breathes so you don't sleep hot.

Comfort Specs

The HIVE® transition layer has precision-cut channels that carry away even more heat and moisture. It's enough to make you feel like you're weightlessly resting on a cloud.
Amerisleep's Bio-Pur® material features an advanced-open cell design. This makes Bio-Pur® more breathable and responsive than memory foam, which will keep you cool and comfortable all night. Plus we make Bio-Pur® from partially plant-based sources using a zero-emission process. That means it's the most eco-friendly material of its kind.

Tuft & Needle Adaptive® Foam
We've engineered a new foam based purely on customer feedback, unparalleled in comfort and support. It's not memory foam or latex. It's Tuft & Needle Adaptive® Foam.

Support Specs

Bio-Pur® contours to your body to relieve pressure points and bounces back fast, so you won't feel "stuck" during the night.
Our HIVE® transition layer provides targeted support and pressure relief so you can sleep in perfect alignment. It gives your head, back, and legs more support, and your shoulders and hips more cushion.

Supportive Base Layer
Our custom Tuft & Needle Adaptive® Foam is paired with a high-quality support layer that forms the perfect foundation for our mattress.
Our foam is ideal for sleepers of any size or weight - and this is what makes it unique. The more pressure you put on it, the more it reacts to support you.

Fabric Specs

Refresh Cooling Cover
The Refresh Cover draws heat from your skin for a delightfully cool-to-the-touch feel. On average, your sleeping surface will stay 7 degrees cooler over an eight-hour night of rest compared to a traditional 100% polyester cover. This scientifically engineered fabric uses minerals to help convert your natural body heat into far infrared energy. This type of energy increases blood circulation to help speed up muscle recovery and improve quality of sleep.

Our plush Tuft & Needle Original Mattress cover is made with a blend of micro polyamide and polyester. It has a lofty, soft feel which is very pleasant to the touch. Micro Polyamide is commonly used in clothing for men, women, and children as an alternative to cotton that dries 6-8 times faster, helping you sleep cooler, longer. With durability in mind, we've designed a fabric that will last. Our mattress cover fabric is pilling-and tearing-resistant. We ask that customers do not remove our cover at any time, as the cover is not designed to be removed for any reason. The zipper on the bottom of the mattress is for assembly only.
Add antimicrobial protection by HeiQ for an additional $50.
