Let’s delve deeper into what makes the Casper Select 12” Hybrid Medium-Firm Mattress a standout choice.

Overview of the Casper Select 12″ Hybrid Medium-Firm Mattress

The Casper Select 12″ Hybrid Medium-Firm Mattress is a Costco exclusive, designed to provide a balanced combination of support and comfort. This mattress aims to cater to a wide range of sleepers by blending multiple foam layers with pocketed coils.

Construction and Materials

The Casper Select features a thoughtful construction that includes several layers, each contributing to its overall performance:

• Poly Foam: The top layer is 1.5 inches of poly foam. This layer is designed to provide immediate comfort and contouring. It also helps in limiting heat retention, ensuring a cooler sleep experience.
• Memory Foam: Beneath the poly foam lies 1.5 inches of gel memory foam. This layer offers pressure relief by molding to the sleeper’s body shape. The gel infusion helps in maintaining a neutral temperature.
• Support Foam: The next layer is another 1.5 inches of poly foam, acting as a transition layer. This foam has a higher density to distribute weight and pressure into the support layer below.
• Support Layer: The base consists of 7.5 inches of high-density support foam. This layer provides the foundational support and structure for the mattress.

All the foams used in the Casper Select are CertiPUR-US certified, meaning they are made without harmful chemicals and have low VOC emissions.

The mattress is topped with a hand-sewn cover made from a blend of polyester, cotton, rayon, and lycra. This cover is thin, breathable, and has a zipper for easy removal.

Firmness and Feel

The Casper Select 12″ Hybrid Medium-Firm Mattress is rated at a 6.5 out of 10 on the firmness scale. This medium-firm feel is designed to offer a balanced foam feel that caters to a broad range of sleepers.

• Balanced Foam Feel: The combination of poly foam and memory foam layers provides a balanced feel. It offers enough contouring for pressure relief while maintaining support.
• Zoned Support: The mattress includes zoned support, which means the foam is firmer under the hips and waist for better spinal alignment, while softer under the shoulders for pressure relief.

This construction and firmness level make the Casper Select suitable for various sleeping positions and body types, although it might be more comfortable for back and stomach sleepers due to its supportive nature.

Performance Tests and Results

Cooling Performance

The Casper Select performs well in cooling, but it’s not exceptional. During tests, the mattress reached a maximum temperature of 85.8°F after 15 minutes of lying on it. This temperature dropped by 6.1°F in the first minute and by 11.2°F after five minutes.

The open-cell foam layer helps with breathability, allowing some airflow. However, the all-foam construction limits its cooling capabilities compared to hybrid or coil-based mattresses.

Motion Transfer

Motion transfer on the Casper Select is moderate. In our tests, the acceleration range was 11.73 m/s², which is higher than the average of 8.64 m/s². This means you might feel your partner’s movements more than you would on other foam mattresses.

The minimal sinkage of 1.63″ and the medium-firm feel contribute to this higher motion transfer. The mattress doesn’t absorb movement as well as others, making it less ideal for light sleepers who share a bed.

Edge Support

Edge support is one of the strong points of the Casper Select. During sitting tests, the sinkage was 3.75″, better than the average of 4.07″. When lying down, the edge support remains excellent, providing a stable and supportive feel.

This makes the mattress suitable for couples who need to use the full surface area of the bed, ensuring you won’t feel like you’re about to roll off when sleeping near the edge.

Response Time and Bounce

The Casper Select has a very fast response time. It mostly recovers in 0.3 seconds and fully recovers in 0.9 seconds, which is average. This quick response time helps prevent a stuck feeling and makes it easier to move around on the mattress.

However, the mattress has a low level of bounce, with a total bounce height of 6.93″, compared to the average of 9.69″. While this might make the mattress less ideal for sex, it does help with motion isolation.

Pressure Relief

The Casper Select offers good pressure relief, thanks to its combination of comfort and support layers. The comfort layer is 4.5″ thick, providing enough cushioning for pressure points like hips and shoulders.

The zoned support foam underneath ensures that heavier parts of the body, like the hips, sink in just enough to maintain proper spinal alignment. This makes it a good option for back sleepers and some side sleepers, although it might not be soft enough for those with severe hip or shoulder pain.

In the next section, we’ll explore how the Casper Select performs for different sleeping positions and its overall support.

Sleeping Positions and Support

The Casper Select 12″ Hybrid Medium-Firm Mattress is designed to cater to a variety of sleeping positions and body weights. Here’s how it performs:

Back Sleepers:

Back sleepers will find the zoned support system particularly beneficial. The mattress is firmer in the middle, providing excellent lumbar support. This helps keep the spine in neutral alignment, which is crucial for avoiding back pain.

Side Sleepers:

The top layers of poly foam and memory foam offer good pressure relief for side sleepers. However, some side sleepers, especially those with sensitive hips or shoulders, might find the mattress a bit too firm.

Stomach Sleepers:

Stomach sleepers require a firmer surface to keep their hips from sinking too far. The Casper Select offers decent support for stomach sleepers, but those who primarily sleep in this position might prefer a firmer mattress.

Weight Categories:

• Lightweight Sleepers (Under 130 lbs): Lightweight back and side sleepers will find the mattress supportive and comfortable. Stomach sleepers in this category will also find adequate support.
• Average Weight Sleepers (130 – 230 lbs): Average weight back and side sleepers should feel well-supported. Stomach sleepers might find it slightly lacking in firmness.
• Heavyweight Sleepers (Over 230 lbs): Heavyweight back sleepers up to 270 lbs can find comfort, but those above this weight might need a more supportive mattress. Heavyweight side and stomach sleepers may find it too soft and lacking in support.

Durability and Off-Gassing

Durability:

The Casper Select is expected to last between five and seven years. It uses high-density foams, but the absence of coils might lead to sagging over time, especially for heavier users.

Off-Gassing Period:

As a bed-in-a-box, the Casper Select does have an initial off-gassing period. When unboxed, it emits a chemical smell, which is typical for foam mattresses. Most of the smell dissipates within 48 hours in a well-ventilated room. However, some users have reported the smell lingering for up to a week.

Sex and Noise

Bounce and Response Time:

The Casper Select is quite responsive, making it a good option for sex. The top poly foam layer adds some bounce, and the mattress allows for easy movement without feeling stuck.

Edge Support:

The mattress has surprisingly good edge support for an all-foam model. This allows couples to use the entire surface area without feeling like they might roll off the edge.

Noise Levels:

Being an all-foam mattress, the Casper Select is virtually silent. You won’t hear any creaking or squeaking, which can be a plus for light sleepers or those who share their bed.

In the next section, we’ll compare the Casper Select with other popular mattresses like the Casper Original and Nectar to help you make an informed decision.

By understanding these general characteristics, you can better assess whether the Casper Select meets your specific sleep needs and preferences.

Frequently Asked Questions about the Casper Select 12″ Hybrid Medium-Firm Mattress

Is the Casper Select the same as the Casper Original?

No, the Casper Select is not the same as the Casper Original. Although they share some similarities, there are key differences:

• Construction: The Casper Select features an additional memory foam layer beneath the top layer, offering a slightly different feel and support.
• Price: The Casper Select is generally less expensive than the Casper Original, but you need a Costco membership to purchase it.
• Availability: The Casper Select is exclusively sold at Costco, while the Casper Original is available through multiple retailers, including Casper‘s own website.

The extra layer of memory foam in the Casper Select provides more contouring, which some sleepers might prefer.

How firm is the Casper Select mattress?

The Casper Select is a medium-firm mattress, rated about 6.5 out of 10 on the firmness scale. This firmness level provides a balanced feel, combining support and comfort:

• Back Sleepers: Ideal for maintaining spinal alignment.
• Side Sleepers: Offers decent pressure relief at the shoulders and hips.
• Stomach Sleepers: Provides enough support to keep the hips from sinking too much.

This makes it a versatile choice for various sleeping positions and weight categories.

Does the Casper Select sleep hot?

The Casper Select does a decent job of keeping sleepers cool, but it may not be the best option for those who tend to sleep very hot. Here’s why:

• Open-Cell Foam: The top layer features open-cell technology, which promotes airflow and helps dissipate heat.
• Breathability: The mattress is designed to be breathable, but it might not be as effective as some hybrid mattresses with coils for airflow.

For those who are particularly concerned about sleeping hot, a mattress with additional cooling features or a hybrid design with more airflow might be a better fit.

The Casper Select 12″ Hybrid Medium-Firm Mattress stands out as a solid choice for those seeking a balanced blend of support and comfort. Exclusively available at Costco, this mattress combines the best of both worlds: the supportive nature of coils and the contouring comfort of foam.
