Casper Original vs. Loom & Leaf – Which One is the Best?

Having originally been developed for aeronautical and space-flight purposes, memory foam has taken over the sleep industry, backed by its plush comfort and soft contouring response. Today, manufacturers incorporate memory foam into their products in its pure form, by modifying its structure or by combining it with layers of other materials.

Casper Original and Loom & Leaf are two products that are primarily built upon the enveloping response of memory foam.


The manufacturers have used modified viscoelastic foam, injecting it with gel to counteract heat retention issues while also using materials such as polyfoam to provide firm support to the sleeper. This Casper Original vs. Purple comparison aims to explore each product’s strengths and weaknesses, helping you decide which suits your need in the best manner possible.

Casper Original Breakdown

Memory foam is popular for its soft, contouring response, but at the same time, it lacks in some respects, particularly thermal regulation and responsiveness. Casper Original has attempted to tackle these issues by incorporating a layer of special open-cell foam over the viscoelastic layer.

The entire mattress is held tightly together by a cover of pure polyester. Soft upon touch and significantly thick, it is fairly breathable, setting up airflow at the surface. Being removable, the cover can be washed and reused.

First Layer

The first layer is composed of 1.5 inches of special open-cell foam, featuring a response similar to that of memory foam. It adjusts according to the body’s contours, sinking in, but at a reduced pace, neutralizing any feelings of uneasiness or entrapment. Furthermore, as it has an open cell structure, it is more responsive to any changes you may make to your sleeping posture during the night, something that can’t be expected from the dead response of viscoelastic foam. Heat dissipation is achieved through the cellular design that sets up airflow and keeps the surface cool.

Second Layer

The layer is responsible for injecting plush response, working in conjunction with the open-cell foam to sink your body into the mattress. The main reason for placing memory foam beneath the open-cell foam is to counter non-responsiveness and heat retention. The strategic placement lets you enjoy the typical contouring response of memory foam but at the same time lets you move around easily over the mattress. In addition, as the layer doesn’t make direct contact with your body, it would be difficult for any trapped heat to cause annoyance as you sleep.


Third Layer

This marks the end of the comfort layer and the beginning of the transition layer that ensures that the body gets a smooth transition between the soft memory foam and the harder polyfoam base. With a thickness of 1.5 inches, the layer is made of transition foam that elicits a mixed plush-conforming response, slowing down the pace at which the body is sinking.

The layer features special zoned design, meaning it is firmer at concentrated pressure points, e.g. lower back, and softer at lighter points such as shoulders. The zoning gives the body targeted pressure relief and maintains spinal alignment for individuals with varying body weight.

Fourth Layer

5.5 inches of high-density polyurethane foam forms this layer, providing unyielding support to the mattress’ layers and the body. After the initial layers contour according to your body’s posture, it is this layer’s responsibility to stop any sinkage, which may otherwise lead to excessive strain on the joints.

Firmness and Feel

Comfort and Support

Medium-firm is the only comfort level in which the mattress is offered. ILD ratings of each of the layers have been kept discrete to prevent imitation from competitors, however, it has been stated that the mattress adapts according to the sleeping styles of all users. The unique design of the comfort layer does make this possible as it brings both softness and responsiveness to the mattress, the latter being missing in typical memory foam products leading to excessive sinkage and nuisance. The base provides ample compressive support to the body and keeps the spine aligned, with its high-density structure improving the mattress’ longevity.


Edge Support

Memory foam mattresses are notorious for poor edge support due to their compressive response to load. But as the Casper Original features a responsive open-cell foam layer, it is able to fare much better compared to typical viscoelastic products. Furthermore, the polyurethane base generates a stiff response and keeps the upper layers upright as pressure is applied to the edges.



Viscoelastic foam is the culprit behind pockets of heat buildups within mattresses. By placing the layer beneath the open-cell foam, Casper Original has been able to keep the surface cool. This has been aided by the structure of the first layer, which is breathable and sets up airflow, making the mattress suitable for hot sleepers.

Motion Transfer

Excessive sinkage within the mattress is a common complaint by people who use memory foam products. The incorporation of the responsive open-cell foam helps counter this problem, making it easier for the body to change positions. One may think that this responsiveness may lead to poor motion isolation.

This isn’t true, as the uppermost layer has a primarily contouring response, damping any movements locally rather than transferring them sideways. Surely, the layer does possess an inner push of its own, but it is hardly noticeable while you’re sleeping.

Unique Features

Plush Comfort aided by Conformity

The Casper Original gives you the chance to enjoy the contouring response of a memory foam mattress, minus any potential episodes of entrapment. In a nutshell, the mattress possesses properties of both viscoelastic and latex rubber, yielding to bodily pressure but conforming your posture at the same time. This makes the mattress suitable for a wide range of sleepers with varying styles and weights.


Cool for a Plush product

Memory foam mattresses carry the risk of heat retention with them. The manufacturer’s strategic placement of viscoelastic foam beneath the first layer allows the sleeper to reap its soft response but avoid its thermal pitfalls. The open-cell foam is breathable on its own and eliminates any heat buildups that may otherwise affect the sleeper.

Edge Support

As you’ll read later, the Loom & Leaf doesn’t have an upper responsive layer, resulting in poor edge support. On the contrary, the Casper Original has an open-cell layer that has a slightly latex-like push of its own, which when combined with the stiff response of polyurethane foam leads to better edge support, allowing you to utilize the maximum surface area.


Targeted Support

The transition layer of the mattress doesn’t follow a uniform ILD rating, being stiffer at high-pressure points and softer at low ones. This zoned design results in the body getting optimum pressure relief as well as spinal alignment, making the mattress a good choice for consumers with varying weight.

Less Expensive

Compared to Loom & Leaf, the mattress is less expensive, with the price going down further through our coupon code. This means that for a reasonable price, you get to enjoy the plushness of memory foam and latex-like responsiveness, without worrying about the thermal issues associated with the former.

Loom & Leaf Breakdown

The Loom & Leaf consists of various modified viscoelastic foam layers but largely issues a plush, contouring response. The mattress is available in two firmness levels.
