Casper Select Mattress Firmness and Feel

Casper Select Mattress Firmness

At Mattress Nerd, we like to rate mattress firmness on a scale of 1–10, where a 1 is the softest possible and a 10 is like sleeping on bricks. That said, the Casper Select comes in at a medium-firm 6.5 on the scale.

The middle-of-the-road firmness will appeal to most sleepers, especially lighter sleepers and back sleepers. However, some heavier sleepers may want to opt for something firmer.

What Does the Casper Select Feel Like? 

The Casper Select is an all-foam mattress, so you can expect to get less bounce and more sinking than a spring mattress. This also means that the Select does a solid job of muffling unwanted movement or noise from the bed. However, the Casper Select is still quite responsive and bouncy for an all-foam mattress. Overall, this bed feels lifted but soft.

And, since this Casper mattress is less on the firm side, it still feels lifting and supportive, especially on the lower back. And lastly, for temperature, this bed doesn’t stand out among other foam mattresses, but it does feel slightly cool to the touch when you first unbox it.

What Sleeping Position Is the Casper Select Mattress Best For?

Weight CategoryBACK SLEEPERSSTOMACH SLEEPERSSIDE SLEEPERS
Lightweight< 130 lbs:544
Average weight130 – 230 lbs:543
Heavyweight> 230 lbs:532

1 = Very poor     2 = Not good     3 = Fair     4 = Good     5 = Excellent

Back Sleepers

The best mattresses for back sleepers do their job by supporting the natural curves of the sleeper’s spine and keeping pressure off of the back. And, not coincidentally, it seems like the Casper Select was literally made for back sleepers. Whether you’re a lightweight, average-weight, or heavyweight sleeper, this all-foam bed has an ideal balance of softness, cushioning, and firm support for your lower back.

Side Sleepers

Next up, the best mattresses for side sleepers are beds that reduce pressure on key areas like the hips and shoulders, and also have enough softness to “sink” into. For the Casper Select, you shouldn’t have any issues getting that support and cushion if you’re a lightweight or average-weight sleeper, but heavyweight side sleepers may need a firmer mattress.

Stomach Sleepers 

Stomach sleepers do best on a bed that will keep their hips from sinking; the best mattresses for stomach sleepers are usually a little firmer and supportive. So, for the Casper Select mattress, lightweight and average-weight sleepers shouldn’t have any issues with staying lifted enough on top of this bed, despite its softness. However, this sinking will be an issue for heavyweight sleepers who need more hip support.

Combination Sleepers 

The best mattresses for combination sleepers allow you to move around and change positions without having to fight against the mattress. For lightweight combination sleepers, the Casper Select should provide enough bounce and support to do this, but average-weight and heavyweight sleepers may want a more responsive, lifted mattress.

Casper Select Mattress Performance

Is the Casper Select Mattress Cooling?

If you tend to sweat or overheat during the night, the Casper Select probably shouldn’t be at the top of your list. While this mattress feels slightly cool initially, it doesn’t have any noticeable cooling when lying down on it.

Edge Support 

The best mattresses for couples usually have solid edge support, meaning that you and your partner can spread out and lie on the edges without falling off onto the floor. For seniors too, edge support can also be important for getting in and out of bed. And, in this case, the Casper Select has pretty killer edge support for a foam mattress—you shouldn’t have any issues here.

Responsiveness

Responsiveness is how well your bed lets you move across it, something that’s a must-have for combination sleepers. For the Casper Select, although this mattress is on the softer, more sinking side, it still has enough bounce to it for combination sleepers to enjoy.

Motion Isolation: Is it good for those who share a bed?

For couples, if your mattress has good motion isolation, then you won’t feel your partner tossing, turning, and getting up during the night. The Casper Select, like many other all-foam mattresses, has outstanding motion isolation—its foam layers absorb any disturbances.

Noise

Just like with motion isolation, the Casper Select’s all-foam design kills it at keeping your bed quiet. So, if your partner’s (or your own) movement is causing creaking on your current bed throughout the night the Casper Select might make a great next mattress.

Pain Relief

For sleepers needing pain relief, the Casper Select’s supportive foam design targets back pain the best, but sleepers with shoulder and hip pain may not be as satisfied. For heavier sleepers, especially side sleepers, the Casper Select can cause pressure to build up in the shoulders.

Sex

The best mattresses for sex are quiet, responsive, and cooling. Although the Casper Select isn’t great for couples who might overheat, this mattress has all of the quietness you’d expect from an all-foam mattress with extra bounce.

Off-Gassing

Just like the “new car smell,” mattresses can come with a new smell too. In the case of the Casper Select, you shouldn’t have any issues with odor when unboxing it. Also, this mattress is CertiPUR certified against any harmful emissions.

Durability 

Usually, foam mattresses aren’t the most durable due to them being softer and deforming more easily. However, the Casper Select has a durable construction, along with its strong edge support which prevents warping on its edges.

Casper Select Mattress Construction: What’s it made of?

The Casper Select mattress is made entirely from foam, similar to the original Casper mattress, but is still designed to provide a medium firmness and bounce. Overall, the Casper Select comes in at 12 inches tall and has a soft feel on top with responsive support layers.

Let’s take a closer look at this mattress’s layers:

inside casper select

Open-cell foam: First up, this top layer of foam is breathable and soft, designed to keep excessive heat from building up around the sleeper. 

Memory foam: Next, below the Casper Select’s top layer of foam, is a dense, comfort layer of memory foam. For sleepers, this layer offers contouring and pressure relief.

Zoned support layer: Getting deeper in the Casper mattress, next up is the foam Zoned Support layer. This layer is responsible for most of the firmness in the Casper Select, and it provides alignment for sleepers’ backs. 

High-density foam base: Finally, the Casper Select’s high-density foam base layer is the firmest of all the layers and serves to keep you elevated when lying on the bed.

Addressing Casper Select Mattress Complaints

  • Pain for stomach sleepers: Some stomach sleepers have reported the Casper Select mattress feeling uncomfortable and placing unwanted pressure on their hips. Specifically, customers have cited that the mattress sinks too deep, lacks firmness, and sags under their bodyweight. This issue applies mostly to heavier sleepers and some average-weight sleepers as the Casper Select lacks enough firmness for these kinds of sleepers.
  • Odor: Several customers have also reported that the off-gassing smell of the Casper Select was unusually strong and didn’t dissipate, even after days of ventilating their room. One customer complained that their mattress has a noticeable smell up to a month after they had purchased it. Although we didn’t notice any significant odor when unboxing the Casper Select, any odors you may notice are nontoxic and harmless.

The Casper Select comes in a little bit softer than the Tuft & Needle mattress, but it is also more durable (meaning you’ll get better edge support and longevity out of your mattress).

Casper Select Mattress FAQs

What Makes the Costco Casper Different?

Between the Casper Select from Costco and the original Casper, the main differences are cost and construction. Firstly, you’ll actually be saving on the Casper Select, although you’ll need a Costco membership to buy it. For construction, the Casper Select actually comes with an additional layer of foam support.

Can You Sleep on a Casper Mattress Right Away?

Yes. Once you’ve unboxed your Casper Select mattress, and it has expanded to its full size, you can sleep on it as soon as you put the sheets on. However, Casper recommends securing the mattress on an appropriate frame and orienting it right side up before lying down.

Are Casper Mattresses Toxic?

No. The Casper Select is made in the United States and is certified by CertiPUR-US against any harmful or toxic emissions to you or the environment. Also, the Casper Select mattress does not contain any harmful compounds and will not affect your home’s air quality.

The Nerd’s Take: What’s the Bottom Line?

The Casper Select is an all-foam, medium-firm, and budget-friendly mattress that works best for back sleepers and lightweight sleepers. Also, this bed’s foam construction provides surprisingly good edge support plus excellent motion isolation and noise reduction, but some hotter sleepers may want a cooler mattress.
