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.

The 13" Cypress is a medium feel - great for back, side and stomach sleepers or partners with different sleeping preferences. The 11" is great for back and stomach sleepers that occasionally sleep on their sides.
Want extra support? The hybrid is the one for you.

Mattress Construction

Materials Overview

Three layer construction:

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

Redesigned for 2020, the new Cypress Memory Foam Mattress costs less than the competition while ensuring greater comfort and quality. This top-selling mattress is made in Los Angeles and available in two thicknesses offering different feels (prices and construction based on the 13" all-foam model):

  • 2" Charcoal Infused Memory Foam
  • 2" Charcoal Infused Memory Foam
  • 1" Foam
  • 8" Contour Cut Polyurethane Base Foam.
There is also two options for support : All-foam or Hybrid. Prices and info based on the 13" Luxe version.

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.

The key to quality sleep is staying cool. In this regard, the Cypress truly excels. The breathable knitted cover, charcoal-infused memory foam, and contour cut foams work together to promote airflow and cooling, all night long.

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.

The Cypress mattress delivers deeper contouring support, relief from pressure points and a softer sleep experience.
The hybrid includes all the benefits of the Memory Foam Mattress plus our innerspring unit with coil support. Precision crafted, pocketed coils effortlessly distribute your body's weight, absorb partner movement, and relieve aching pressure points, while structurally reinforcing the perimeter to eliminate that "roll-off-the-edge" feeling.

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.

Charcoal is full of beneficial properties that are perfect for mattresses, like temperature and moisture control. Plus, charcoal is completely natural. The Cypress Memory Foam mattress is charcoal-infused, so while the bed has plush contouring comfort, it is also super breathable. The charcoal-infused foam works hard to move moisture and heat away from your body, so all you do is stay dry, cool, and comfortable - all night long.

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.

Charcoal-infused memory foam relieves pressure points by distributing weight evenly across the mattress. Ideal for couples, it isolates motion so you won't disturb your partner while you sleep. With the perfect amount of cradle and cushion, the memory foam creates a medium plush feel that's great for partners with different sleep preferences.
A solid support base absorbs your weight to dampen motion transfer and prevent noise.

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.

The cover is a luxurious soft knit that breathes effortlessly made of 99% polyester, 1% spandex.
