Casper vs. Amerisleep Mattress Comparison

Casper Mattress Review Highlights

• Targeted Support: Casper’s comfort layer features Zoned Support™. That’s their trademarked way of saying that you’ll experience the right amount of firmness for each region of your body.
• Top-Rated for Side Sleepers: The Casper mattress is a tested and true top pick for side sleepers. It scored remarkably high for pressure relief and spinal alignment, both of which are important categories for side sleepers.
• Responsive: Casper is also a slam dunk for combo sleepers. It scored 10/10 in our responsiveness assessment.
• Broad Appeal: Mattresses with a medium to medium-firm feel are comfortable for most sleeping positions. Casper is 6/10, or medium-firm, on the firmness scale, which has a comfy blend of contouring and support for back sleepers, stomach sleepers, and side sleepers alike. 
• Breathable: Casper designers wanted a cooler mattress than traditional memory foam, so they added tiny holes in the foam to allow your body heat to flow away.
• You can also see if the Casper Element, Casper Hybrid, Casper Nova Hybrid, or Casper Wave Hybrid may be better for you.

Amerisleep Mattress Review Highlights

• Motion Transfer: The foam layers absorb motion from movement before they affect the rest of the mattress surface. This is a feature that couples look for, since motion isolation reduces sleep disruptions.
• Cooling: The AS3 mattress features Amerisleep’s Bio-Pur® material, which is designed to keep you cool with an open-cell structure. 
• Eco-Friendly: The Bio-Pur memory foam is made with renewable plant-based oils and way fewer petrochemicals than traditional memory foam. It’s also CertiPUR-US® certified, which is better for your family and the planet because there is less off-gassing in the environment and your home. 
• HIVE Technology: The AS3 transition layer is constructed with Amerisleeps’ HIVE technology, which keeps your spine aligned, reduces stress on pressure points, and creates a sleeping-on-clouds feel.
• 20-Year Warranty: You have 2 decades with your Amerisleep mattress before it’s out of warranty, while most mattresses’ peak performance years happen in the first decade.
• For various firmness levels, check out the AS1, AS2, AS4, and AS5.

Inside The Casper Mattress

• Soft Cover: Casper makes their soft polyester cover from up to 57 recycled bottles. 
• Airscape™ Foam: This is the softest layer on the Casper mattress. It’s made of polyfoam, which is a little lighter than memory foam. It’s also perforated, which creates channels for warm air to travel away from your body. 
• Memory Foam Layer: Casper’s middle foam layer is composed of Zoned Support™ memory foam. The foam under your shoulders is softer, while the foam under your hips is firmer. These ergonomic zones help to keep your spine in its natural alignment, which can prevent or alleviate back pain.
• Durable Base: At the base of the mattress is a thick foam layer. It’s a bit firmer, so it keeps you from sinking too far into the mattress. It also prevents sagging.

Inside the Amerisleep Mattress

• Celliant Cover: Celliant material is engineered to transform your body heat into infrared energy that cools and rejuvenates your muscles, regardless of your body type. It’s a great pick if you notice that you are frequently sleeping hot.
• Bio-Pur Foam: Amerisleep’s proprietary Bio-Pur foam is eco-friendly and breathable. It has an open-cell structure that improves air circulation under your body.
• Affinity Transition Foam: This foam layer is designed with targeted ergonomic support that enhances spinal alignment and eases stress on pressure points.
• Support Layer: The polyurethane foam base is 7” thick. It serves as a durable, supportive foundation for the whole mattress.
