Who Makes It?

The mattress is made by IDLE Sleep, whose founder has more than 18 years of experience in the industry. IDLE Sleep currently makes four 2-sided mattress models, including an All-Foam option and a Latex option.

Comfort Levels

IDLE Sleep makes a range of 2-sided mattresses but if you’re particularly interested in the 14” Hybrid option, you can choose between two different comfort levels: Medium and Luxury Firm. Learn more on which to pick HERE.

My review is for the Medium bed. As you can see, it comes in at about a 5.5-6 out of 10 in the firmness range, according to the company. Typically, average firmness is about 6.5-7 out of 10, which makes this just slightly under average firmness.

The medium is designed for all sleep positions and may suit people who sleep in multiple positions at night. Since it is just under average firmness and contains softer contouring layers on top, it really is probably the best fit for side sleepers who benefit from added pressure relief.

The Luxury Firm comes in just above average and is a good fit for those who sleep primarily on their stomach, back or are heavier or have a larger body frame.

Mattress Construction & Durability

The 14” Hybrid mattress is made up of layers of foam surrounding a coil unit. Keep in mind that the mattress is 2-sided. This means that you can flip the mattress over and it’ll be the same layers on one side as the other.

Here is a breakdown of each layer of the Hybrid mattress:

  • The cover is made with Thermocool™ fabric. Idle Sleep says the fabric is designed to work with the body’s natural thermal capabilities through smart fiber cross-sections. It helps you to feel “warm when you are cold and cool when you feel hot.”
  • 1” IDLE quilting foam is quilted into the cover for added comfort.
  • 1” IDLE Air Flow Response Foam: This is a bouncier latex-like layer that’s custom blended for IDLE sleep and aerated to promote breathability. 3.6lb density; IFD 20
  • 2” IDLE Cooling Buoyancy Foam is another custom blended foam that IDLE says has billions of microscopic air bubbles within the foam that provide a cloud-like feel and exceptional pressure relief (as compared to a traditional memory foam). 3.5lb density
  • 6” Quantum Edge-To-Edge Pocketed Coils – this coil unit system has over 1,000 coils in a Queen size mattress which helps enhance its durability and the coils come right up to the edge to promote edge support as well.

The three foam layers at the top of the mattress will then be featured underneath the coil system since the mattress is 2-sided.

In terms of durability, the density of both the IDLE Air Flow Response Foam and the IDLE Cooling Buoyancy Foam is high and the Quantum Edge pocketed coil system is also considered good quality. All of these factors combine to make the bed a nice quality and durable mattress.

You Might Like The 14” Hybrid Idle Sleep Mattress If…

  • Sleep on your side. The mattress is about a 5.5-6 out of 10 on the firmness scale. While 6.5-7 is about average and the best for back sleepers, anything under the average tends to be softer and most pressure relieving – ideal for side sleepers who put weight on their shoulders, hips, and knees overnight.
  • You are looking for the pressure relieving benefits of memory foam without sinking in too much. The top foam layers of the mattress are interesting because they have the bounce and quick response of latex but once you lay on the bed you feel the foam contour to your body. This really gives it a pressure relieving feeling overall but you won’t feel “stuck” in your bed.
  • You are a hot sleeper. One of the nice features of a hybrid mattress is that the coil system inside the bed tends to help promote airflow (compared to an all-foam bed). The IDLE Hybrid has a layer of Cooling Buyoancy foam and an aerated layer of IDLE Air Flow Response Foam that will help it breathe. Finally, the Thermacool fabric woven into the outer fabric helps regulate the body’s natural temperature as well.
  • You want your mattress to last a very long time. One of the perks of a 2-sided mattress is that you can increase the longevity of your bed by rotating it and flipping it consistently so it wears evenly over a longer period of time. With the quality of the materials, you will certainly have this mattress for the long haul.

You Might Not Like The 14” Hybrid Idle Sleep Mattress If…

  • You like that traditional memory foam feel.  Memory foam gives you that feeling of slowly sinking further and deeper into your mattress. You are more likely to say you’re sleeping “in” your bed than “on” it.  It’s cozy and it’s comfortable, but this bed – with its coil system and faster response foam layers – has more of a bounce and spring to it.
  • You are a heavier person. The mattress in a Medium is on the softer side and may not be as comfortable or supportive enough for stomach sleepers or heavier individuals. The best bet would be to go with a Luxury Firm (or another option entirely)
  • You’re on a budget.  The Queen mattress runs for $1,499 at full price and probably won’t fit everyone’s budget. If you’re looking for something a little less expensive, check the site for sales and promotions and you can also consider the IDLE Dual Feel mattress option for $1,199 for a Queen.

Firmness & Feel

As you can see from the video, the foam layers on the top of the mattress have a quicker response than traditional memory foam. The coil system underneath the layers also helps provide some overall bounce to the mattress.

The firmness is close to a 5.5-6 out of 10 – with a 6.5-7 being about average firmness. This puts the mattress at just below average firmness and, based on my experience, it even felt a little softer than Medium.

Check out the video below to get an idea of how the mattress feels.

Motion Isolation

The mattress is quick to respond and has more of a bouncy feel than traditional memory foam so I wasn’t sure if the motion isolation would be perfect. As you can see from the video, the foam layers still do a good job of isolating motion and I believe the coil system is helping to stabilize weight distribution as well.

Edge Support

The Quantum Edge-to-Edge coil system goes to the very edges of the mattress to provide support. However, the mattress also has  4″ of softer foam on top. I could use most of the surface area of the bed but when I sat up to get off the bed, I could feel that foam compression on the edge.


What Makes This Mattress Stand Out?

What really makes this mattress, and pretty much all IDLE Sleep mattresses, is their 2-sided design.

The pressure relief is also very noticeable. I don’t sink into the mattress but it feels soft and buoyant, which probably has to do with this foam combination on top, including their custom blended Cooling Buoyancy foam layer.

I enjoyed reviewing my first 2-sided mattress. One thing I appreciated was that the company used good quality materials and good construction, so the bed should last you a very long time (especially if you increase the longevity by flipping it).

The Medium firmness option felt a little bit softer than Medium to me and I really liked the pressure relief I felt when I laid on my side. Heavier individuals or those sleep primarily on their stomachs may prefer the Luxury Firm version.

The mattress comes with a 120-night trial period.
