Nectar vs Casper Original - Which is the Best Investment?

With the dawn of internet-based commerce, the competition in the sleep industry has become incredibly stiff as many mattress makers relying solely on internet-based delivery have sprung up, giving competition to established names such as Serta and Sealy.

Nectar and Casper Original are two such newcomers who have carved out significant chunks of the market for themselves because of their premium quality features and affordable pricing.


I’ve written this Nectar vs Casper Original comparison to discuss the strengths and limitations of these high-end foam mattresses with respect to each other, with the idea that it will help you decide which one is better suited for your sleep style.

Breakdown of Nectar Mattress

The Nectar is a typical memory foam mattress uses extra-firm lower layers to counter some of the sinkages that are generated by its plush upper layers.

The Nectar boasts a cover made from Tencel® fiber – this material has organic origins since it is derived from eucalyptus trees. It is soft and light, and in fact has better breathability than organic cotton, resulting in a comfortable, cool and skin-friendly surface for you to sleep on.

The manufacturer has a free replacement policy for this cover (separate from the main warranty policy), should it become damaged – all you have to do is call them.


First Layer

1” of quilted gel viscoelastic foam is used to create the top layer of the mattress. It is given a rating of 14 ILD, which corresponds to the highly cushioning and adaptive response that it generates. This layer absorbs some of the initial impact of your body on the bed, and the gel incorporated into its foam structure means that it is much better at transporting heat away from the surface than ordinary memory foam products.

Second Layer

Next, we have a second layer of gel memory foam, but this one has a thickness of 3” and an ILD rating of 15. The increase in thickness and firmness translates into a slightly greater viscous drag i.e. this layer still contours to your body, but in a slower manner than the upper layer – thus, it is responsible for aligning to the posture you assume during sleep.


Third Layer

This layer uses high-end adaptive Hi-Core viscoelastic foam at a thickness of 0.5 inches. This foam is known for its robust lumbar support, and its placement in the transition layer definitely indicates that the manufacturer wanted to incorporate this property into the mattress.

Besides the lumbar support, this layer also slows down the sinkage of your body further inwards and binds the soft upper layers with the stiff base underneath. It has an ILD rating of 45, which is a bit stiffer than most transition layers but is necessary for the resistance it needs to create against your weight.

Fourth Layer

The lowermost layer of the Nectar offers solid, unyielding support for your body after the upper layers have adapted themselves to the contours of your body and absorbed the immediate pressure. This layer keeps your body from sinking down further (which can lead to awkward stress on your joints and muscles due to the resulting misalignment of your spine).

To generate this tough response, this layer has been made from 55 ILD 2.2 lbs./cu.ft. polyurethane foam, and a healthy 5.5-inch thickness.

Firmness and Feel


Comfort and Support

There is only a medium-firm firmness level in which the Nectar is available, and this combines the plush response of memory foam with the stiff reaction of extra high-density polyurethane. As a result, you get an evenly balanced overall feel that has both pressure relief and support.

It is worth noting that the Nectar, by virtue of its Adaptive Hi-Core foam transition layer, is a bit firmer and more supportive than most other viscoelastic products – this isn’t unpleasant: rather, it reduces some of the sinkings feelings that are exhibited by the material. Of course, Casper’s open-celled structure takes care of that in a bit more responsive fashion, so the Nectar is definitely a truer viscoelastic product than the Casper in any case.


Edge Support

The Nectar, like any other mattress that uses viscoelastic foam so generously, tends to sink a bit when you put your weight at sides. However, it doesn’t sink all the way down (like most memory foam products), because the sharp increase in ILD rating in the third and fourth layers is able to counter the yielding nature of the upper layers.

As such, it fares much better than your average memory foam mattress in this department. The Casper’s response, for different reasons, is also quite similar.


The Nectar fares reasonably well in this department (better than most memory foam mattresses at least) thanks to the heat absorbing action of its two upper layers, and the ventilation enabled by the breathable Tencel® cover and the air channels in the base. The stiffer response of the base and intermediate layers also reduces some of the cradling effects of the upper layers, so you don’t feel trapped in your own body heat that much.

That being said, the Casper does better than the Nectar, because its open-cell foam upper layer is more effective at removing heat than all the features mentioned above.

Motion Transfer

The Nectar’s purely viscoelastic upper layers (and an intermediate layer too) ensure that practically all impacts on the surface are absorbed locally and do not disturb the surroundings. Even the little bounce that is present in the Casper because of the open-celled foam is absent in this case: in short, the Nectar yields the typical dead response of a memory foam mattress in terms of motion isolation.

Unique Features

Affordably priced

The Nectar is considerably less expensive than the Casper (particularly when you factor in the discount it currently ships with). Despite its lower cost, it doesn’t compromise on the quality of its materials and has an industry-leading trial and warranty policies. Put short, the Nectar is a premium quality memory foam mattress selling at a bargain price.

Signature viscoelastic feel with lessened sinkage

Where the Casper deals with memory foam’s lack of response and sinkage through modified open-celled foam that gives the mattress some latex-like bounce, the Nectar sticks to the tried and test formula of memory foam, but instead throws in a layer of extra-firm memory foam in the middle to enhance the resistivity of the mattress to your weight.

Although this doesn’t make the mattress more responsive to changes in your sleep position per se, it does reduce the cratering effect that memory foam creates, which makes the surface far easier to move around on.
