The Casper Cooling Select Hybrid is an inexpensive hybrid mattress available exclusively at Costco U.S. It's a Medium-Plush mattress with a pocket coil support system beneath layers of polyfoam, memory foam, and gel-infused polyfoam. Like the Casper Cooling Select, the all-foam variant of this mattress, each layer is CertiPUR-US certified, meaning they contain lower levels of indoor air pollutants and heavy metals.

The Casper Cooling Select Hybrid is best-suited to average-weight and heavier side sleepers. If you fall into either of those categories, you'll sink far enough into the mattress to relieve pressure on your arm, shoulder, and hip when sleeping on your side, which keeps your body in the proper alignment so you don't wake up sore. Unfortunately, lighter-weight side sleepers don't compress the mattress enough, leading to uncomfortable pressure, especially on the shoulder.
Fantastic pressure relief for heavier people.
Excellent pressure relief for average-weight people.
Mediocre pressure relief for lighter people.
Lack of contouring, leaving less cushioning for your joints.

The Casper Cooling Select Hybrid is a satisfactory option for back sleeping. It's most supportive for lighter people who don't sink very far into the mattress. If this describes you, your hips should stay lifted, keeping your back in a fairly straight line. Its performance is nearly as good for average-weight and heavier people, so regardless of your weight, you should find that it's supportive enough to keep you decently comfortable throughout the night.
Satisfactory support for most sleepers.

The Casper Cooling Select Hybrid is decent for stomach sleepers. It provides moderate support, regardless of your weight, which helps keep your hips lifted, so your back doesn't arch when sleeping on your stomach. You may want a firmer option if you consistently sleep in this position, but it's supportive enough to avoid considerable discomfort.
Satisfactory support for most sleepers.
The Casper Cooling Select Hybrid offers mediocre durability. This mattress uses a combination of low-, good-, and high-quality foam, so you can expect it to sag and form permanent body impressions faster than options that only use higher-quality materials. The upper comfort layer is made of dense, high-quality gel-infused polyfoam, so you can expect it to withstand wear and tear. However, the lower comfort layer is made of low-quality memory foam, while the lumbar section of the transition layer is made of low-quality polyfoam. The transition layer at the head/foot of the mattress uses slightly denser, good-quality foam, so you can expect this mattress to sag in the lumbar section first.
High-quality upper comfort layer.
Lower layers may begin to sag sooner.
The Casper Cooling Select Hybrid's pressure relief performance depends on your weight. It relieves the most pressure for heavier people who compress the mattress the most. Sleepers in this category will find that their shoulders and hips sink far enough into the mattress to keep them comfortable through a night of side sleeping. Similarly, average-weight sleepers get excellent pressure relief, making it a solid choice for side sleepers in this weight range. Lighter sleepers, however, will probably find this mattress too firm, especially for side sleeping. It's not very contouring, either, which means less cushioning for your joints.

The Casper Cooling Select Hybrid offers decent support. Light-, average-, and heavier-weight sleepers will all find that this mattress keeps their hips lifted high enough to stay pretty comfortable. You may find that your spine is not in the ideal alignment when sleeping on your back or stomach, but it's supportive enough to avoid any serious discomfort.
Satisfactory support for most sleepers.
The Casper Cooling Select Hybrid delivers impressive cooling performance. It transfers enough heat to keep most sleepers feeling refreshed throughout the entire night. If you have trouble falling asleep because of the heat, you might need something with slightly more efficient cooling, but its performance should leave almost everyone comfortably cool, especially as the night progresses.
Cooling enough for most sleepers.
The Casper Cooling Select Hybrid is very good at dissipating motion. While you feel movement nearby, it doesn't spread across the entire mattress, and it doesn't last long. For example, when your pet jumps onto the foot of the bed, you feel it around your feet, but not at your head, and it fades quickly enough that it's unlikely to wake you up.
Motion subsides quickly.
Motion stays localized, helping you sleep soundly with a partner.
The Casper Cooling Select Hybrid is a very bouncy and responsive mattress. It responds quickly when you compress it, which avoids any lifeless or sluggish feeling and ensures that shifting sleeping positions is easy.
Highly responsive, making it easy to move around.

Popular Mattress Comparisons
The Casper Cooling Select Hybrid is an affordable mattress with a Medium-Plush firmness level. This mattress is the hybrid variant of the Casper Cooling Select, and as such, there are some noticeable comparisons between these two Costco exclusives. The all-foam version is a bit more supportive, making it a better bet for back and stomach sleepers, while the Hybrid's pressure relief is better suited to side sleepers. The addition of a spring layer makes the mattress bouncier and more responsive, but also means that it can't isolate motion as well. This makes the foam variant better for couples who want to sleep peacefully together, and the Hybrid ideal for sleepers who want a mattress that's easy to move around on.
If you're looking for a more supportive option available at Costco, consider the Novaform Legacy, which provides better performance for stomach sleepers. It's also more responsive, and it does a better job of dampening movement from a partner who tosses and turns. If you want better pressure relief, on the other hand, you might like the Novaform Serafina Pearl, which is a better choice than the Casper Cooling Select Hybrid for side sleepers. It also isolates motion well to help you sleep soundly, but it's less responsive and more difficult to move around on.

The Kirkland Stearns & Foster Pillow Top Lakeridge and the Casper Cooling Select Hybrid are pretty evenly matched overall, but they have a few differences to consider. Go for the Kirkland Stearns & Foster if you sleep on your side, since it offers a little extra pressure relief, which helps cushion your shoulder in this position. Its excellent motion dissipation also makes it a better choice for partnered sleepers, especially if one tends to toss and turn. The Casper, on the other hand, offers more support for back and stomach sleepers. It's also a better choice for hot sleepers, since it transfers more heat away from you throughout an eight-hour night.
The Casper Cooling Select Hybrid is a better mattress than the Saatva Classic (Luxury Firm). It provides better support and pressure relief, making it a more comfortable option for a range of body types and sleeping positions. The Casper is also a better choice for couples; its effective motion isolation means that movement is less likely to wake you. It's also more cooling, so it's a good choice for hot sleepers. And while it's not the most durable mattress out there, its denser foam layers should help it resist sagging and indents longer than the Saatva.
The Casper Cooling Select Hybrid is a better mattress than the Novaform ComfortGrande Plus for most people. While both mattresses offer decent support, the Casper provides more pressure relief, making it more comfortable for side sleepers. It's also more responsive, making it easier to change sleeping positions, and it offers more efficient cooling for hot sleepers. That said, if you sleep with a partner, you'll feel less of their movements on the Novaform, so it's a reasonable option for couples.
The Silk & Snow Mattress provides a better overall performance than the Casper Cooling Select Hybrid, but either option can be a good choice depending on your priorities. Choose the Silk and Snow if you sleep on your side or if you sleep with a partner. It provides more pressure relief, which helps cushion your shoulder and hip while side sleeping, and you notice less movement across the mattress, helping you sleep peacefully. Go for the Casper if you sleep on your back or stomach, since the extra support helps lift your hips, keeping your back in more of a straight line in either position. It's also more responsive, so you might like it if ease of movement is important to you.
Test Results
The Casper Cooling Select Hybrid is nearly 12 inches tall, so standard fitted sheets should work well.
This Medium-Plush mattress is best-suited to average-weight and heavier side sleepers, but its mix of decent support and good pressure relief makes it a solid choice for back and stomach sleepers, too. Lighter side sleepers may find that they need an even plusher option.
The Casper Cooling Select Hybrid is most conforming for average and heavier-weight sleepers who sink most deeply into the surface. Sleepers in either of these categories will compress the mattress enough to relieve pressure on the arms, shoulders, and hips when sleeping on their sides. Lighter-weight sleepers still get passable pressure relief, but if you fall into that category, you'll probably want a softer option for regular side sleeping.
Regardless of your weight, this mattress provides decent support. Lighter-weight sleepers will find it most supportive, but the difference is minor for average and heavier-weight sleepers. It does a satisfactory job of keeping your hips lifted, which helps keep your back in a straighter line. If you sleep on your back or stomach most nights, you may want something with more robust support, but you shouldn't find that your hips sink too far into the surface.
The spring layer at the bottom of this mattress is quite bouncy. While the foam layers, which aren't particularly resilient, dampen some of this bounciness, it's still a lively, springy option overall, and it feels very easy to move around on.
The soft comfort layers allow you to sink deeply into this mattress, but they don't provide much contouring. As a result, you feel like you're sleeping more 'in' than 'on' this mattress, but without the hugging sensation commonly associated with memory foam.
The surface of this mattress regains its shape very quickly after you compress it. This responsiveness supports each of your movements, making it easy to roll over or reposition yourself throughout the night.
The Casper Cooling Select Hybrid provides very good motion isolation. Nearby movement is very noticeable, so you feel it when your partner rolls over, or your pet jumps on the bed, but only near the source. It doesn't travel across the mattress, and it fades quickly, meaning that it's less likely to bother or wake you up.
Although this mattress has polyfoam built into the sides, it's not very supportive. Sitting or sleeping near the edge creates a ramp that leaves you feeling like you might slip off. The cover is very slippery, too, which exacerbates this feeling. In fact, when we tested this mattress using our naturalistic loading pad, the cover slipped out from underneath it, causing the mattress to 'bottom out.' Ultimately, if you need a solid surface to get in and out of bed or just want to maximize the usable sleeping surface, you should consider an option with sturdier edges.
This mattress offers impressive cooling. Its performance in this regard improves throughout the night, so if you sleep hot, you may find it a little too warm as you fall asleep. Still, its heat transfer is effective enough for most people and keeps hot sleepers comfortably cool throughout most of an eight-hour night.
The cover contains 59% polyester, 40% polyethylene, and 1% spandex. Although it has a zipper, the cover is not removable or washable.
Although there's an additional layer of polyfoam built into the sides, it doesn't provide much support. As a result, this mattress offers inadequate edge support.
There are three layers of foam above the pocket spring support system. The upper comfort layer is made of gel-infused polyfoam; it's less resilient, or bouncy, than standard polyfoam, contributing to the mattress's very good motion isolation. Below that is a memory foam comfort layer, which allows you to sink a little farther into the mattress. The polyfoam transition layer is zoned, with softer polyfoam at the head and foot of the mattress and firmer polyfoam in the lumbar region, which ensures your hips don't sink too far.
This mattress uses a mix of low-quality, good-quality, and high-quality foam. The polyfoam upper comfort layer is dense enough to be considered high-quality and should resist forming indents for longer than the less dense layers below. The memory foam lower comfort layer is made of low-quality foam, so you may notice that it starts to sag prematurely. The zoned transition layer uses low-quality polyfoam for the lumbar section and slightly denser foam that just reaches the cut-off for good-quality foam (27kg/m3) at the head and foot of the mattress. As a result, you may find the mattress sags more noticeably in the lumbar area.
There are 4.1 inches (10.4 cm) of foam above the pocket springs. The gel-infused polyfoam in the top layer is 1.5 inches (3.8 cm) thick. Regardless of your weight, you'll sink through this layer and into the 1.3 inches (3.4 cm) memory foam lower comfort layer. The transition layer is also 1.3 inches (3.4 cm) thick, which helps ensure you don't notice the individual coils below.
The support layer contains 14-gauge springs, which help support the heaviest parts of your body that sink through the comfort layers.
All of the foam layers in this mattress are soft. The gel-infused polyfoam upper comfort layer is the firmest overall, though it's still fairly cushy. The memory foam lower comfort layer is much plusher, allowing you to sink quite deeply into the mattress. Both sections of the transition layer are also soft, but the lumbar section is firmer than those at the head and foot of the mattress, giving you extra stability for your hips. Together, these layers contribute to the mattress's effective pressure relief and make it a good choice for most side sleepers.
The spring layer is very firm. It's slightly firmer at the head and foot of the mattress, but the difference isn't noticeable. The zoned transition layer, which is firmer in the lumbar section, also counteracts this effect, making the mattress as a whole a little firmer in the lumbar region.
The gel-infused polyfoam in the upper comfort layer is less resilient than standard polyfoam, but it still bounces back a fair amount when you compress it, making it easier to move around. The memory foam in the next layer down is much less resilient, which is expected of this material, and allows you to sink more deeply into the mattress. The polyfoam transition layer provides the most resilience overall, in both the head/foot and lumbar areas, adding to the mattress's overall bounciness.
