Casper vs. Nectar Mattress Review

Below, we compare the beds’ construction, materials, firmness levels, and more to help you decide whether to buy the Nectar or the Casper mattress. We also share shipping and return policies, warranty coverage, and information about company reputation.

Casper Construction

The Casper mattress is a mixed-foam mattress that’s made with a 100% polyester cover that has stretchy side panels for easy unzipping and cleaning. It contains two comfort foam layers: one 1.5-inch layer of standard polyfoam and a second 1.5-inch layer of 4 PCF memory foam. Together, the comfort layers give the bed a light bounce and body-contouring pressure relief. The transitional layer contains 1.5 inches of 2.5 PCF polyfoam and prevents sleepers from sinking too deeply into the base layer, which contains 7.5 inches of 1.8 PCF high-density polyfoam to stabilize the bed. Altogether the Casper measures 12 inches thick and a medium feel that is conforming yet supportive as it cushions the body.

Nectar Construction

The Nectar mattress is a mixed-foam mattress that’s made with a breathable TENCEL lyocell and cotton cover that’s removable and machine-washable for easy cleaning. It contains two comfort foam layers including a quilted gel memory foam layer that’s one inch thick and three inches of 3.5 PCF gel memory foam. Together, these layers hug but the body but do not sink deeply. The transitional layer contains 1.75 inches of high-density memory foam and enhances the slight body hug of the top layers. The support core of the Nectar Mattress contains 5.25 inches of 2.2 PCF high-density polyfoam that contributes most to the firmer feel of the mattress. Altogether, the Nectar measures 11 inches thick and has a medium-firm feel yet conforms to the body.

Things to Consider When Picking A Mattress

Firmness / Feel—The Nectar mattress is considered medium-firm, whereas the Casper mattress is considered medium on the firmness scale. The Nectar may feel a little too firm for some sleepers, especially lightweight sleepers and side sleepers who require a softer mattress for better hip and shoulder pressure point relief and alignment. 

Motion Isolation—Motion isolation is essential for those who sleep with partners and wake easily in the middle of the night. Both of these beds offer minimal motion transfer well and hardly make any noise while bearing weight. See: Best Mattresses for Couples 

Edge Support—Edge support generally refers to whether a bed sinks when sleepers sit on its edges, and most memory foam mattresses tend to sink a bit. Both the Casper and the Nectar have significant sinkage when seated at the edges, but they do perform a little better than other all-foam mattresses in this category. Edge support is most important for mattress durability and for those who have trouble getting in and out of the bed, like the elderly or the disabled.

Pressure Relief—Pressure relief, or a mattress’s ability to conform to areas of the body where pressure, pain, or discomfort typically occur in any sleeping position, is essential regardless of your weight, height, or preferred sleeping style. If you enjoy the sensation of sleeping “in” a mattress, you may enjoy the Casper more. However, both beds offer pressure-relieving conforming, you’ll just notice a deeper hug with the Casper. The Nectar conforms but the overall feel isn’t as soft.

Spine Alignment—Spinal alignment is essential for overall health whether you’re a side, stomach, or back sleeper. How well a bed contributes to your spine’s health will vary based on your weight, sleeping position, height, and whether the bed is tailored to offer proper support for your body type. The Nectar best supports spinal alignment in back and stomach sleepers who are average weight or heavyweight. Side sleepers may find proper spinal alignment on the Nectar if they weigh more than 230 pounds. The Casper conforms more closely and is suitable for side, back, and stomach sleepers who are lightweight or average weight. 

Durability—Both beds are relatively new to the market (2014 and 2016), so their maximum longevity is still being determined. You can expect both models to have an average lifespan of about seven years, which is standard for the mattress industry. Durability is an essential factor to consider in all-foam beds, which are generally less durable than hybrid mattresses and innerspring mattresses because they lack a responsive coil support core. Keep in mind that, with any foam mattress, you may notice body impressions forming over time. We recommend rotating both of these mattresses every six months to avoid this.  

Cooling / Temperature—All-foam mattresses tend to sleep hotter than innerspring and hybrid beds because of their support foam cores, which aren’t as breathable as pocketed coils. Solid-foam base layers don’t promote as much airflow, but the Nectar and Casper offer relatively good temperature neutrality for all-foam beds, with the Casper sleeping a little cooler than the Nectar.

As we’ve seen, the Nectar Mattress and the Casper Mattress share some similarities and also differ in several ways. We think the key differences between these online mattress models are the deciding factors. Setting motion isolation and temperature control aside, as both beds excel in these areas, consider your sleeping position, weight, and sleeping circumstances. If you enjoy a medium-firm feel and moderate conforming and weigh at least 130 pounds, you’ll probably enjoy the Nectar. If you enjoy a slightly softer feel with more noticeable conforming and are lightweight or average weight, you’ll probably enjoy the Casper.
