Idle Sleep is an online, direct-to-consumer mattress retailer. Idle gives customers an exceptionally long 18-month sleep trial during which they may try out mattresses risk-free. Idle Sleep sells four mattress models: the Idle Gel Foam, the Idle Gel Plush, the Idle Hybrid, and the All Natural Latex. This page focuses on the Idle Hybrid Mattress.

According to Idle Sleep, the Idle Hybrid Mattress is their best seller. The support coil and foam mattress costs less than Idle Sleep’s All Natural Latex Mattress, but more than the Idle Gel Foam and Idle Gel Plus.

The Idle Sleep Hybrid is available in two firmness options: “medium,” which measures six out of 10 on the firmness scale, and “luxury firm,” which measures at an eight out of 10. Customers may also opt for a mattress that measures “medium” on one side and “luxury firm” on the other.

All of the Idle Hybrid Mattress options are flippable. The mattress with both firmness levels gives customers two options in one bed. Mattresses with the same firmness on both sides allow sleepers to extend the lifespan of their mattress by distributing wear across both sides.

In this Idle Hybrid Mattress review, we provide details about the bed’s construction, materials, and performance. We also review Idle Sleep’s relevant policies, such as their shipping practices, sleep trial, and warranty.

Idle Hybrid Mattress Review Breakdown

As a hybrid mattress, the 14-inch Idle Sleep Hybrid contains a mixture of materials. At the center of the mattress sits the bed’s primary support core. This core consists of a 6-inch thick layer of pocketed coils.

Because the pocketed coils are individually encased (unlike traditional innersprings, which interconnect), they reduce both noise and motion transfer across the surface of the bed. Compared to polyfoam support cores, coils allow increased airflow, which keeps the bed cooler.

On each side of the coil layer lies the same sequence of foam layers. Since the Idle Sleep Hybrid is a flippable bed, these layers serve dual purposes. The layers sitting above the coil layer act as comfort layers. When these layers sit below the coil layer, they act as part of the support core.

The deepest foam layer consists of polyfoam and measures one inch in thickness. This layer acts as a transitional layer and helps provide support. Above it is a two-inch layer made with what the company calls IDLE Buoyancy Foam. Buoyancy Foam is similar to memory foam, but more responsive.

A softer foam, called IDLE Contouring Foam, forms the outermost layer. One inch of this foam is quilted into the mattress’s cover. The cover is made of Thermocool fabric, a material designed to promote cooling.

The Idle Sleep Hybrid Mattress comes in two firmness levels. The company calls these options “medium,” which measures medium firm, and “luxury firm,” which measures firm. Mattresses of all firmness options are constructed with the same materials and measure the same height.

Prices and Sizing

The Idle Sleep Hybrid costs more than Idle Sleep’s foam mattress offerings, but less than its latex mattress. This pricing is as expected. Generally, hybrid mattresses cost more than all-foam beds but less than latex mattresses due to costs associated with each material type.

Compared to other hybrid mattresses, the Idle Sleep Hybrid sells at prices toward the upper end of average.

Mattress Performance

Motion Isolation

Medium Firm: 3/5, Firm: 2/5

Because it contains contouring foam layers, the Idle Hybrid isolates motion well. These comfort layers tend to absorb movement, rather than allow it to travel across the surface of the mattress. The medium firm firmness option isolates motion even better than the firm option because it’s softer.

Motion isolation is important to sleepers who share a bed with a partner, especially those who are sensitive and wake up easily. When a bed isolates motion well, sleepers aren’t likely to be disturbed when their partner moves around during the night or gets in and out of bed. Hybrid beds like the Idle Hybrid transfer less motion than innerspring mattresses because of their individually encased pocketed coils and foam comfort layers.

Pressure Relief

Sleepers can expect to experience pressure relief while lying on the Idle Hybrid. The beds’ materials and construction promote an even distribution of weight across its surface. The transitional layer helps relieve pressure by allowing heavier parts of the body to sink in more deeply while still being supported. The contouring foam layers conform to the body, providing further pressure relief.

Beds that do not relieve pressure well cause pressure points that can create discomfort and even pain over time. Oftentimes, a bed doesn’t relieve pressure well because it is too firm for the sleeper’s body weight. When heavier parts of the body such as the hips and shoulders do not sink into the bed at least a little, spinal alignment is compromised and pressure points tend to develop.

Temperature Control

Medium Firm: 3/5, Firm: 4/5

Most sleepers find that they remain cool on the Idle Hybrid throughout the night. The coil support layer allows for increased airflow compared to the support cores of all-foam beds. Also, Idle Sleep notes that they designed their foam comfort layers to make them sleep cooler than memory foam does. Finally, the fabric used to cover the mattress is also designed for cooling.

Sleepers who tend to sleep extremely hot might still find themselves warm on the Idle Sleep, especially if they purchase the medium firm option. Because of differences in the foam layers, the medium firm option doesn’t sleep quite as cool as the firm option.

Edge Support

Medium Firm: 3/5, Firm: 4/5

Due to its pocketed coil support layer, the Idle Hybrid provides adequate edge support for most sleepers. Edge support factors into how much of a bed’s surface a sleeper may use. When a bed has strong edges, sleepers can use the full surface of the bed without feeling at risk of rolling off due to buckling edges. Edge support tends to be most important to people who share a bed with a partner, children, or pets and need to make full use of the space.

Some sleepers, especially those of heavier weights, might prefer a mattress with even stronger edges. The edges do bend some beneath body weight. The firm option provides edges that are a bit stronger

Ease of Movement

Medium Firm: 3/5, Firm: 4/5

Foam layers combined with a pocketed coil support core give this bed a feel that is both conforming and responsive. As a result, moving across the surface of the Idle Hybrid feels relatively easy to most sleepers. The IDLE Buoyancy Foam comfort layer is specifically designed to allow sleepers to move freely on the bed while enjoying the conforming feeling associated with memory foam.

Although the Idle Hybrid doesn’t technically contain memory foam, it provides a similar feel. Some sleepers, especially those who do not like to feel “hugged” by their mattress, might find this sensation inhibits some of their movement on the mattress. The firm option is a bit bouncier and easier to move around on than the medium firm.


Medium Firm: 3/5, Firm: 4/5

Most people find the Idle Hybrid works well for sex. It’s a virtually silent bed with adequate edge support on which movement is relatively easy. Generally, hybrid beds like this one work better for sex than highly conforming all-foam beds, which can inhibit movement and make changing positions awkward or uncomfortable.

Although most sleepers find the Idle Hybrid works well for sex, some prefer an even springier mattress. Innerspring mattresses and less conforming hybrids provide more bounce, which facilitates movement more than a bed with conforming properties.


Like most mattresses, the Idle Hybrid off-gasses a limited amount. Off-gassing refers to the release of volatile organic compounds (VOCs) from newly manufactured materials. Customers can expect to smell a slight odor upon opening their sealed mattress as a result of off-gassed VOCs. This odor should dissipate quickly, likely within hours.

Hybrid mattresses like this one tend to off-gas less than all-foam beds. Foam is the mattress material known for off-gassing the most. Pocketed coils make up six inches of the Idle Hybrid’s thickness. Not only does this coil layer off-gas less, it allows for airflow that can help carry away off-gassed VOCs from the foam layers.

Sleeping Style and Body Weight

Side Sleepers:
The Idle Hybrid rates exceptionally well with side sleepers weighing between 130 and 230 pounds. This group finds that the bed’s construction promotes spinal alignment and relieves pressure. The transitional layer allows the heavier parts of the body to sink into the mattress in a way that supports all body parts.

Side sleepers of all body weights find comfort on the Idle Hybrid. Side sleepers weighing less than 230 pounds generally prefer the medium firm mattress option. The firm option is too firm for them and may cause pressure points. Those weighing over 230 pounds can choose whichever firmness level feels most comfortable to them. The more a person weighs, the more likely they will prefer the firm mattress option.

Back Sleepers:
Back sleepers of all weights also find comfort on the Idle Hybrid. In this sleep position preference group, sleepers weighing less than 230 pounds may enjoy either the medium firm or firm mattress options depending on their preferences. Both firmness levels provide adequate support, but the medium firm feels softer and more conforming while the firm feels more responsive.

Back sleepers weighing over 230 pounds tend to require the support provided by the firm option of the mattress. The mattress rates exceptionally well with this group. On it, they experience adequate lumbar support, so their backs don’t over-arch. For this reason, many mattress reviewers on the Idle Sleep website note that the mattress helps alleviate back pain they experience on other mattresses.

Stomach Sleepers:
Of all sleepers, those who prefer sleeping on their stomachs rate the Idle Hybrid the highest. Stomach sleepers weighing over 130 pounds in particular tend to find adequate support on the firm option of this bed. Stomach sleepers weighing less than 130 pounds may enjoy both the medium firm and firm levels. The flippable option with different firmness levels on both sides might work well for this group.

Stomach sleepers generally require a firmer mattress, which is why sleepers in this group weighing 130 to 230 prefer the firm option. Soft mattresses can allow the bodies of stomach sleepers to sink in too far, putting strain on their necks. These pressure points often lead to discomfort and even pain. Stomach sleepers do not run into that problem on the Idle Hybrid. Instead, the entire body is well supported and spinal alignment is promoted.
