Material & Construction

Q1. What are the unique technology, design, and materials used in the construction of The Casper Mattress?

The Casper mattress features a three-layer foam design and a cozy knit cover. It begins with a stretchy cover followed by a top layer of breathable aerated foam. Underneath lies a middle section featuring zoned support, concluding with a sturdy bottom layer of high-density poly foam.

This combination of materials aims to achieve a balanced and medium-firm feel.

  • Cover: Crafted from a knit polyester blend, the mattress cover of the Casper boasts a soft and stretchy texture.
  • Comfort Layer: Casper’s Airscape® foam serves as the top layer. This material responds slowly to pressure, allowing sleepers to sink in and experience relief from pressure points, particularly in the shoulders and hips.
    While this contouring effect might typically cause overheating, the foam’s surface features small aerations that enhance breathability, facilitating airflow and dissipating trapped body heat.
  • Transition Layer: The subsequent layer consists of memory foam designed to provide zoned support. It has three distinct zones; each zone offers a slightly different level of firmness.
    Softer foam, situated around the shoulders, alleviates pressure, while firmer foam supports the hips, offering a gentle lift. This meticulous zoning creates a harmonious and well-balanced sensation, promoting a healthy, neutral spine alignment.
  • Base Layer: This mattress rests on a thick layer of high-density poly foam at its base. This layer furnishes structural integrity and stability to the overall mattress design.

Q1. How would you rate The Casper Mattress from a repositioning & responsiveness perspective? 

  • Repositioning refers to how easy or difficult it is to change positions on a mattress. A mattress with good repositioning allows you to move and adjust your body without feeling stuck or restricted. Responsiveness, on the other hand, refers to how quickly a mattress adapts to changes in pressure and movement.
  • The Casper mattress is easy to reposition. This is because the top layer of perforated polyfoam is soft and comfortable but not too soft. This means you can easily move around on the mattress without feeling like sinking into it. The second layer of zoned memory foam also helps prevent sinkage, making repositioning easier.
  • Responsiveness
    The Casper mattress is also responsive. This means that it can quickly bounce back into shape after you move. This is important for people who sleep hot, as it helps to keep the mattress cool. The responsiveness of the Casper mattress also makes it easy to change positions without feeling stuck.

Comfort, Back Support, Pressure Relief


Q2. How would you rate The Casper Mattress for providing comfort and pressure relief to sleepers? 

The Casper mattress is a good choice for people who want a mattress that is both comfortable and provides pressure relief. The perforated polyfoam top layer and the zoned memory foam help to create a soft, cushiony surface that conforms to your body and relieves pressure on your joints and muscles.

Here is a detailed look at how the Casper Mattress offers comfort and pressure relief to sleepers:

  • Comfort: The Casper mattress is comfortable and suitable for a variety of sleeping positions. The top layer of perforated polyfoam is soft and cushiony, but it is also not too soft. This means you can sink in enough to feel supported but not so much that you feel like you are sinking into the mattress.
    The second layer of zoned memory foam provides additional comfort and pressure relief. The zoned memory foam is firmer in the middle, which helps to prevent sinkage and supports your lower back.
  • Pressure Relief: Sleepers often experience pressure points in their hips and shoulders, as these areas tend to be wider and heavier, exerting more pressure on the mattress. Insufficient contouring can result in the accumulation of pressure.
  • The Casper Mattress addresses this issue by providing close conformity to the sleeper’s body, effectively redistributing body weight and alleviating pressure points. The memory foam layer offers additional support, specifically around the midsection, preventing excessive sinking of the hips. This combination of pressure relief and support can be particularly beneficial for individuals experiencing aches and pains.
  • The medium firm feel of the Casper mattress suits sleepers weighing under 230 pounds. Most individuals within this weight range should experience adequate sinkage for comfortable contouring and well-balanced support. However, sleepers over 230 pounds might find the Casper slightly too soft, potentially leading to increased pressure points if the foam compresses excessively.

Cooling & Temperature Control


Q3. How would you rate the cooling and overall temperature control characteristics of The Casper Mattress?

The Casper mattress traps less heat than many other all-foam mattresses. The top layer of perforated polyfoam allows air to circulate, which helps to dissipate heat away from the sleeper’s body.

The second layer of zoned memory foam is firmer in the middle to prevent sinkage, and it is also more breathable than most high-density foams. As a result, the two-layer comfort system conforms closely to the sleeper’s body without trapping as much heat.

Motion Isolation and Sharing a Bed


Q4. Does The Casper Mattresses provide reasonable motion isolation when sharing a bed with others?

The Casper mattress, all-foam mattress is good at motion isolation. This means that movements made by one person on the mattress are less likely to be felt by the other person.

With its two-layer comfort system, the Casper mattress effectively absorbs and minimizes motion transfer. The top layer, made of polyfoam, offers a slightly buoyant sensation, which contributes to reducing the transmission of motion. The layer of memory foam further absorbs movement by contouring the body and preventing it from spreading to other areas of the mattress.

This strong motion isolation proves advantageous for couples who share a bed. If one person tosses and turns during the night, the other person is less likely to be disturbed. This feature is especially valuable for light sleepers or individuals who tend to wake up with the slightest movement or disturbance.

Edge Support


Q5. How would you rate the edge support of The Casper Mattresses?

Many all-foam mattresses lack reinforced edges, which can result in the feeling of instability when approaching the bed’s perimeter. The compression of the foam near the edges may make it more challenging to sit or sleep comfortably in those areas.

The Casper mattress distinguishes itself by incorporating a thicker support core, giving the edges a sturdier feel than many other all-foam models. However, some sinkage may still be noticeable when sitting or sleeping near the edge. Individuals weighing over 230 pounds are likely to experience more pronounced sinkage than those with lighter body weight.

Recommendation based on sleeping style

Side Sleepers:

  • The Casper Mattress suits side sleepers, thanks to its close conforming and pressure relief capabilities. The combination of a polyfoam layer and a memory foam layer in the comfort system provides a contouring effect that alleviates pressure points and offers a comforting embrace. Additionally, the zoned layer prevents excessive sinking of the hips, promoting better spinal alignment for side sleepers.
  • For individuals weighing under 230 pounds, the Casper’s medium firm feel strikes an ideal balance between contouring and support, making it particularly suitable for side sleepers in this weight range.
  • However, side sleepers over 230 pounds may not find it as comfortable. Heavier individuals typically prefer a firmer mattress, and the medium feel of the Casper may result in excessive sinkage and potential misalignment of the spine near the hips and shoulders.

Back Sleepers:

  • Back sleepers generally prefer a medium to medium-firm feel, as they require an even surface that maintains proper spinal alignment while still providing some cushioning. The Casper, being a medium-firm mattress, leans towards the softer end of the range that back sleepers typically favor.
  • Back sleepers weighing under 230 pounds and desiring a softer feel may find the Casper Mattress enjoyable. The two comfort layers of the mattress cradle the sleeper and relieve pressure points. The zoned memory foam layer also provides enhanced support around the hips, preventing excessive sinking for lighter back sleepers.
  • On the other hand, individuals weighing over 230 pounds usually require a firmer mattress to achieve an adequate balance between cushioning and support. The medium feel of the Casper might not provide enough firmness to prevent deeper sinkage around the hips for heavier back sleepers, potentially leading to pressure points and spinal misalignment.

Stomach Sleepers:

  • Stomach sleepers often carry more weight around their midsections, necessitating a mattress with sufficient support to prevent excessive sinking of the hips. Excessive sinkage can lead to poor alignment and strain the sleeper’s spine.
  • The Casper’s zoned layer, which offers extra support in the midsection, can be beneficial for stomach sleepers. However, the medium feel of the mattress may not provide adequate support for some stomach sleepers, particularly those weighing over 230 pounds.
