Idle Sleep is a direct-to-consumer mattress company founded in 2017. In addition to bed sheets, pillows, and mattress foundations, the company currently makes five mattresses. Options include the all-foam Idle and Idle Gel Plush, the Dunlop and Talalay Latex Hybrids, and the Idle Hybrid. This review will focus on the Idle Hybrid.

The Idle Hybrid is a 14-inch flippable mattress constructed with pressure-relieving foams and a pocketed coil support core. The mattress comes in a choice of two firmness levels: medium firm and firm, or a 6 and an 8 out of 10, respectively. Customers can choose whether to order the same firmness level for each side of the mattress, or a different firmness level on each side.

Idle Sleep offers an 18-month long sleep trial and a lifetime warranty for every mattress. These policies are both well above the industry standard, removing much of the risk for consumers who need more time to decide if they like the mattress or not.

The Idle Hybrid’s flippable design, durable construction, and extra-long sleep trial have earned it a spot on our list of the best mattresses of 2021. After a brief look at how the Idle Hybrid compares to the other Idle mattresses, we’ll examine the features of the Idle Hybrid to help you decide if it could be well-suited to your sleeping style.

Idle Hybrid Mattress Review: Our Verdict

With an appealing blend of support and pressure relief, the Idle Hybrid offers all the typical advantages of a hybrid mattress. Its breathability and bounce are well-suited to hot sleepers and combination sleepers of most body types. Couples appreciate its strong edge support and fairly quiet construction. One of the major selling points is the 18-month sleep trial, which gives customers plenty of time to test out the mattress for comfort and durability.

As with most hybrid mattresses, the Idle Hybrid offers neither the deep conforming nor the absolute silence of an all-foam mattress. Moreover, while the Idle Hybrid is reasonably priced for a mattress of this type, budget-minded shoppers may find the price-point slightly out of their range.

Shoppers who favor plush, pressure-relieving foam mattresses may prefer the Idle Gel Plush mattress, while eco-minded customers will be enticed by the Idle Latex mattress. The flagship Idle mattress offers a more affordable all-foam option that’s easier on the wallet.

Choose the Idle Hybrid if…

  • You want more than a year to test out the mattress
  • You’re looking for an extra-supportive mattress that still provides some pressure relief
  • You sleep with a partner and you value ease of movement
  • You tend to sleep hot

Keep Shopping if…

  • You prefer the deep “hug” of a memory foam mattress
  • You’re a very light sleeper and you share your bed with another person
  • You’re on a strict budget

How Does the Idle Sleep Hybrid Mattress Feel?

The Idle Sleep Hybrid mattress is sold in two firmness options, medium firm and firm. Both are constructed with a quilted cover and several layers of pressure-relieving foams over a pocketed coil support core. Depending on firmness level and body type, sleepers will sink more or less into the foam before receiving pushback from the pocketed coils.

The medium firm option offers closer contouring, while the firm option keeps sleepers mostly “on” instead of “in” the mattress. As the mattress is double-sided, customers are offered the choice between having the same firmness option for both sides or a different one for each.

The pocketed coils flex in proportion to the weight applied, meaning they are able to provide targeted support to the areas that need it most. The coils also add responsiveness to the surface for easier movement. Due to the thick comfort layer section and pocketed coil core, the Idle Hybrid provides sufficient support for most sleeper types, including those who weigh more than 230 pounds.

What Is the Idle Hybrid Mattress Made Of?

The Idle Hybrid has a flippable design consisting of three foam layers on each side, plus a shared support core made of pocketed coils. This comes to a total of seven layers overall. With its 14-inch profile, the Idle Hybrid is taller than average and customers may have to buy deep-pocket fitted sheets.

Ordering an Idle Hybrid mattress with the same firmness level on both sides allows customers to periodically flip the mattress in order to delay the onset of body impressions. Those with evolving firmness preferences, or who aren’t sure what firmness they prefer, can request a different firmness on either side. Split King mattresses can also be ordered with a different firmness level for each person.

Cover Material

The cover is made of Thermocool fabric designed to regulate temperature. The cover has sewn-in handles for easier flipping when you want to rotate the sleep surfaces. Beneath the cover sits a natural fire barrier that is free of petroleum-based synthetic materials.

Comfort Layers

Both sides of the Idle Hybrid mattress have the same layers, regardless of firmness level. A 1-inch layer of contouring polyfoam is quilted into the cover for added pressure relief and cushioning. This is followed by 2 inches of a proprietary foam called Cooling Buoyancy Foam. Constructed with breathability in mind, this foam is also highly resilient to prevent sleepers from feeling stuck in the mattress. A final inch of transitional polyfoam helps prevent sleepers from sinking into the coils.

Support Core

The Idle Hybrid mattress has a 6-inch pocketed coil support core. This single layer of coils functions as a support core for both sides of the mattress, providing targeted support for the different areas of the body while reinforcing the edges and keeping motion transfer to a minimum. The queen size mattress has a total coil count of 1,130 coils.

Does it Isolate Motion?

Rating 3/5 (firm), 4/5 (medium firm)

The medium firm Idle Hybrid mattress absorbs most motion to prevent disruptions from sleep partners. This is largely thanks to the comfort layers, which conform closely to the sleeper. As its comfort layers don’t contour as closely, the firm Idle Hybrid allows a little more motion transfer.

Pocketed coils tend to eliminate more transfer than interconnected innerspring mattresses. This is because each coil is wrapped individually, allowing it to move independently of the neighboring coils. While not as effective at motion isolation as an all-foam mattress, the Idle Hybrid should still grant a night of fairly sound sleep to those who sleep with a partner.

Does It Sleep Cool?

Rating 4/5 (firm), 3/5 (medium firm)

As with most hybrid mattresses, the Idle Hybrid sleeps fairly cool. The support core of pocketed coils promotes steady airflow to keep the interior cool. The foams are also designed to be more breathable than traditional memory foam.

In particular, the firm Idle Hybrid model sinks to a minimal extent, resulting in consistent surface airflow for most sleepers. By contrast, the medium firm model hugs the body more closely and may trap a larger amount of heat. However, both models are good options for hot sleepers and should sleep noticeably cooler than most all-foam mattresses.

Will It Sag Along the Edges?

Rating 4/5

The Idle Hybrid is quite supportive around the perimeter due to its pocketed coil support core. The coils prevent excessive sagging around the edges, allowing sleepers to sit on the edge of the bed or sleep near the edge of the bed without feelings of roll-off.

Edge support is a key factor for couples, who rely on a strong perimeter for full use of the bed. It’s also important for those who have trouble getting in and out of bed, and may lean on the edges for extra balance.

Is It Good for Sex?

Rating 3/5

For couples, the Idle Hybrid provides a fairly responsive surface that lends itself well to sex. The pocketed coils provide the necessary pushback to facilitate movement, while the foam comfort layers provide some traction. The breathability and decent edge support of the mattress also help establish a more comfortable surface.

Those who prefer a very bouncy surface for sex may find that the Idle Hybrid falls a little short of expectations. This is especially true of the medium firm model, which can restrict motion due to its closer conforming.

The pocketed coil support core may also start to emit some squeaks and creaks over time, which can be a problem for those who need to be discreet. However, as the coils are individually wrapped, they make much less noise than the coils found in a traditional innerspring mattress.

What About Off-gassing?

Rating 3/5

Some people may notice a faint “off-gassing” smell when they first unbox the mattress. This is the result of volatile organic compounds (VOCs) being released into the air, and it is a process that occurs with virtually any mattress that contains synthetic foams. The smell is not harmful, and in most cases it dissipates within a short time.

Because each mattress is made to order, there’s not much time for odors to build up inside the plastic. The pocketed coil construction of the Idle Hybrid also facilitates airflow and speeds up the off-gassing process. All of the foams used in Idle’s mattresses are CertiPUR-US certified to be low in VOCs and free of other harmful chemicals.

What Type of Sleeper Is the Idle Hybrid Best For?

The Idle Hybrid is best-suited to back sleepers, who benefit from above-average lumbar support thanks to the combination of contouring foams and pocketed coils. The mattress also performs quite well for side sleepers and stomach sleepers, though this may vary depending on body type.

Side Sleepers

Pressure-relieving foams and pocketed coils in the medium firm Idle Hybrid mattress form a comfortable cradle for side sleepers. This mattress cushions the hips and shoulders to reduce pressure points, especially for side sleepers who weigh more than 230 pounds. By contrast, the firm version won’t provide enough cushioning for most side sleepers with the possible exception of those who weigh more than 230 pounds. For those who require extra pressure relief, the Idle Sleep Gel Plush mattress offers a slightly softer feel and closer body-contouring.

Combination Sleepers

Combination sleepers can easily switch positions on both the firm and medium firm Idle Hybrid mattresses. Moreover, the mattress rates well for almost all preferred sleeping positions and body types, making it a good choice for people who move frequently in their sleep. Some stomach sleepers may find that the mattress does not provide enough support to keep the hips from sinking into the mattress. Those who spend most time sleeping face-down would do better to choose the firm version of the Idle Hybrid, or perhaps consider the Idle Latex mattress instead.

Back Sleepers

The Idle Hybrid offers a balanced feel that suits back sleepers of all body types. In general, back sleepers do best on a mattress that provides equal parts support and pressure relief. With four inches of pressure-relieving foams backed by a pocketed coil core, the Idle Hybrid fills in the lumbar area to prevent pressure build-up. Back sleepers weighing less than 230 pounds receive enough support from either the medium firm or the firm model. Back sleepers who weigh more than 230 pounds may lean towards the firm model, which offers more lumbar support.

Stomach Sleepers

As with back sleepers, the Idle Hybrid should be comfortable for stomach sleepers of all body types but their ideal firmness level depends on their weight. Those who weigh less than 130 pounds are more likely to prefer the medium firm feel of this mattress, as the firm option may not contour closely enough or provide enough cushioning. Stomach sleepers weighing more than 230 pounds will probably find the firm feel more comfortable instead. This firmness level will sag less and keep their bodies on a more even plane compared to the medium firm. For stomach sleepers weighing 130 to 230 pounds, either the medium firm or firm feel is potentially suitable. These sleepers should test out both to determine which firmness level best meets their individual needs.

How Does Body Weight Impact Performance?

While the Idle Hybrid mattress comes in medium firm and firm options, sleepers may find that the firmness changes depending on their body weight.

Individuals who weigh less than 130 pounds don’t put as much pressure on the mattress. These sleepers may prefer the plusher feel of the medium firm model as opposed to the firm model. This is most important for those who sleep on their side, as a mattress that’s too firm can cause pressure points to build up in the hips and shoulders.

Those who weigh between 130 and 230 pounds sink in further, deriving closer contouring from the foams. The medium firm model is a better choice for those who prefer to sleep more “in” than “on” the mattress, or side sleepers who need extra cushioning for the hips and shoulders. Stomach sleepers and those who prefer a firmer feel may wish to opt for the firm model instead.

While both Idle Hybrid mattresses feature a robust support system made with pocketed coils, the firm feel is more appropriate for back and stomach sleepers over 230 pounds. These sleepers typically prefer a firmer surface to keep the spine on an even plane. By contrast, side sleepers may choose either the medium firm or the firm model, depending on personal preference. These sleepers sink further down into the mattress and experience conforming pressure relief from both models.

Is the Idle Hybrid Good for Couples?

Both the medium firm and firm Idle Hybrid mattresses include features and characteristics that appeal to couples.

The foam comfort layers and pocketed coil core keep noise levels to a minimum, and the medium firm model isolates motion to a significant extent. This helps to prevent disruptions when one person shifts positions or gets in and out of bed. The firm model allows a little more motion transfer, but offers better temperature neutrality as it doesn’t conform as closely to the sleeper.

Both models offer relatively good ease of movement, with a somewhat bouncy surface that should be adequate for sex. The edges should also hold up under pressure, allowing couples to spread out instead of crowding toward the middle of the mattress.
