Sounds good right? Well there’s more — it’s also a flippable model, which means you can use both sides of the mattress. Two is better than one!

This almost sounds too good to be true, so I wanted to find out if the Idle Hybrid delivered on its promises. I put the mattress through a variety of tests getting all the details from performance to motion isolation, breathability to bounce, and much more.

Is the Idle Hybrid a Good Mattress for You?

Let’s hit the ground running with some of the basics about the Idle Hybrid to help you decide if it’s a good mattress for you. Depending on your height, weight, and preferred sleeping position, the Idle Hybrid may or may not work for you. While I can’t make that decision for you, I can provide you with some recommendations to help you get there on your own.

Who I recommend the Idle Hybrid mattress for

  • The Idle Hybrid’s medium-firm rating makes it a nice model for all sorts of sleepers
  • I recommend back sleepers seriously consider this bed because it provides a mixture of support and pressure relief, which should keep these sleepers’ spines in a nice alignment. 
  • Back and side combo sleepers should like this mattress. The pocketed coils offer a little bit of bounce, allowing for ease of movement.

Who I don’t recommend the Idle Hybrid mattress for

  • I recommend that stomach sleepers go with a firmer mattress, or the Luxury Firm version of this mattress, so that their hips don’t sink too far down, moving their spine out of alignment.
  • If you are a strict side sleeper who prefers a plush feel, this might not be the best pick for you. 

How Firm is the Idle Hybrid Mattress?

One of the most important factors to consider when buying a new mattress is firmness level, which is the initial feeling you experience when you first lie on the mattress. As a disclaimer, firmness is pretty subjective. What’s soft for me might be medium, or even firm, for someone else! I’m around 5’10” and 190 lbs, and I’m a stomach sleeper. These factors might mean that my firmness ratings are different from yours.

Idle Hybrid Firmness
I found the Idle Hybrid to be medium firm

The Idle Hybrid comes in three firmness types: Medium, Luxury Firm, or Medium on one side and Luxury Firm on the other. I tested out the Medium, and I gave that model a 6.5 out of 10 on the firmness scale (1 being the most plush and 10 being super firm). The industry standard is a 6.5 rating for medium firmness, so this is right in line with that.

Idle Hybrid Mattress Performance

Firmness is just one thing to consider when you’re picking out a new bed. To really determine whether a bed is a good match for you, it’s also important to consider how it performed in different sleeping positions, how it relieved pain and pressure, and how it might feel for couples sharing the bed. Let’s dive into those tests.

Testing the Idle Hybrid Mattress in Different Sleeping Positions

Different sleeping positions and weights require different amounts of support. Generally, light sleepers don’t need the same amount of support as heavy sleepers. Read on below to see how the Idle Hybrid mattress performs for sleepers of different weights.

Is the Idle Hybrid a Good Mattress for Light Sleepers (Under 130 lb)?

  • Light Back Sleepers – Light back sleepers tend to feel mattresses a bit firmer than advertised, so I think this bed would be a good option for these folks — if they prefer a firmer touch. This mattress might feel more firm than medium-firm to these sleepers, but will provide tons and tons of much needed support.
  • Light Side Sleepers – This mattress may be a touch too firm for light side sleepers, unless they prefer a firmer feel. Generally, side sleepers need a bit of  sink to relieve pressure at their hips and shoulders, which they won’t get on this bed.
  • Light Stomach Sleepers – Light stomach sleepers are the only stomach sleepers I would recommend this model to. Because of their lighter weight, they may experience the necessary lift to keep their hips in healthy alignment. 

Is the Idle Hybrid a Good Mattress for Average Weight Sleepers (130 – 250 lb)?

  • Average Weight Back Sleepers – I think average weight back sleepers will find a lot to like with this mattress. The hybrid build will make these sleepers feel evenly balanced with a bit of contouring  at pressure points.
  • Average Weight Side SleepersI think the Idle Hybrid is a great option for average weight side sleepers. The bed’s construction will help align their spine, while still relieving pressure at the shoulders and hips.
  • Average Weight Stomach Sleepers Stomach sleepers should only consider the Luxury Firm version of this mattress, as it will better suit their needs.

Is the Idle Hybrid a Good Mattress for Heavy Sleepers (over 250 lb)?

  • Heavy Back Sleepers – Heavy back sleepers will sink too deeply on the Medium version of this mattress, but might find enough support in the Luxury Firm model. 
  • Heavy Side Sleepers – Heavy side sleepers should opt for the Medium version of this mattress, which will provide the sinkage they need while still giving them ample support.
  • Heavy Stomach Sleepers – I recommend heavy stomach sleepers look for a mattress with a stronger innerspring build, but they might find adequate support on the Luxury Firm version of this bed.

Idle Hybrid Pain Relief Performance

Instead of just going by feel, I like to run some specific tests to see how each mattress performs. Pressure/pain relief refers to how well a mattress alleviates tension at pressure points found at the hips, shoulders, and lower back. To figure out how the Idle Hybrid relieves pain, I rolled out a pressure map on top of the model, and then lay in different positions. The device creates a colored map showing pressure, which ranges from blue to green in areas of low pressure to yellow and red in high-pressure areas.

Idle Hybrid Pressure Map
Back and side sleepers will find low levels of pressure on the Idle Hybrid

Back Pain – The pressure map shows blue across the board for this one, suggesting that the Idle Hybrid offers great pressure relief for back sleepers. The combination of foam and coils here works to relieve pain at the lumbar region. On the other hand, stomach sleepers with back pain should opt for a firmer mattress that will prevent their hips from sinking out of alignment with their shoulders.

Shoulder Pain – When lying on my side, the pressure map shows that my shoulders sway into the green range. In my opinion that’s okay for a lot of side sleepers, but it’s not ideal for sleepers with shoulder pain who might want something softer to absorb pressure. Sleepers that really need pain relief at the hips should look for an all-foam mattress that will allow deeper sinkage.

Hip Pain – My weight was pretty evenly distributed when I laid on my stomach. That said, I felt like my hips sank down into the mattress a little bit, which is something strict stomach sleepers should keep in mind as it can lead to back pain. I think back sleepers with hip pain would benefit more from this bed, as the pocketed coils will allow for the necessary structural support to keep sleeper’s hips elevated, while the foam will cushion any existing pain!

Idle Hybrid Performance for Couples

When sharing the bed with a partner, you’ll want to keep a few more things in mind while shopping for a new mattress. Features you’ll want to consider include motion transfer, performance during sex, cooling, and edge support.

Motion Transfer

Motion transfer is particularly important if you share your bed with a partner… or pets. Basically, this test helps evaluate how much disturbance you feel on your side of the bed if someone on the other side starts rolling around or gets out of bed at night.

For this test, I dropped a 10 lb steel ball from heights of 4 inches, 8 inches, and 12 inches onto the top of the mattress, and measured the disturbances using a seismometer: the bigger the lines, the bigger the disturbance.

Idle Hybrid Motion Transfer
Low motion transfer results for the Idle Hybrid make it a nice choice for couples

Overall, I thought the Idle Hybrid did a pretty good job isolating motion. The foam layers in the mattress help to absorb and isolate motion, though the bounce from the pocketed coils does cancel this out a little bit! Overall, I give couples or folks who let their pets sleep on the bed a thumbs up to pursue this mattress.

The pocketed coils in the Idle Hybrid’s structure make this an excellant mattress for sex. The coils beneath the mattress’s foam add bounce and responsiveness, which both assist in changing positions and moving quickly. I would recommend this bed to those looking for a little more activity in the bedroom.


Just as the coils benefit this mattress in terms of sex, they also help with temperature regulating — a win-win! Rather than trapping heat like some all-foam models, this hybrid mattress allows for increased airflow with its pocketed coils. The Idle Hybrid also features a custom foam known as Cooling Buoyancy Foam to keep you from overheating. As if that isn’t enough, the bed’s cover is made with Idle’s Thermocool fabric, which is specifically designed to keep the hottest of sleepers cool.

Edge Support

Last but not least, I evaluated the edge support properties of this model. Basically, a mattress with good edge support allows you to roll all the way to the edges of the bed without worrying that you’ll slide off the bed. This is an important consideration for couples or heavier folks, as good edge support means there is more usable surface area on the bed. 

I was able to roll all the way to the side of the bed without falling off, which means the Idle Hybrid is solid in terms of edge support. The pocketed coils are to thank as they provide support throughout the entire perimeter of the bed.

What is the Idle Hybrid Mattress Made Of?

The Idle Hybrid is—you guessed it!—a hybrid model, meaning it has pocketed coils and layers of foam. It offers a cover made with contouring foam, comfort layers of cooling foam, and six inches of individually wrapped coils for support.

I actually opened up the mattress to look at the specifics. Here’s what’s inside:

Cover – The cover is quilted with 1 inch of contouring foam, providing a soft feel and some pressure relief right off the bat. The cover is made with Idle’s Thermocool™ fabric, which is designed to work with your body temperature. The idea is that the cover feels warm when you’re cold, and cool when you’re overheating. Right below the top layer is a fire-resistant barrier, which the Idle website says is free of carcinogenic chemicals, gases, toxins, HCN, HCI, and bromine.

Comfort Layer The comfort layer consists of 2 inches of Idle Cooling Buoyancy Foam, which is a custom blended foam. This foam reacts a little faster than memory foam, but still does a nice job relieving pressure. It also offers some support and cooling technology.

Transition Layer Under the custom cooling foam, comes 1 inch of a transition foam layer, which is firmer than the foam layers above it. This adds a little more support to the mattress beneath the cushiony, contouring foam included above. Next up comes 6 inches of pocketed coils. The coils offer support and a little bit of bounce, as well as edge support. Having the coils beneath the foam means you don’t get “stuck” in the model, or feel like you’re sinking.

Base – Because the Idle Hybrid is a two-sided, flippable mattress, there isn’t a traditional base layer. Instead, after the transition layer, there is another comfort layer identical to the one above, and then another cover layer. The model has carry handles to make flipping the mattress easier.

Idle Hybrid Unboxing and Off-Gassing

The Idle Hybrid is a bed-in-a-box mattress, which means it will arrive compressed and will have to be unboxed at home. As with all bed-in-a-box mattresses, you’ll need to wait at least 24 hours for this bed to fully decompress. 

As with many new mattresses, the Idle Hybrid will likely emit a smell when it is first unboxed — this is known as off-gassing. If you do detect an odor, I suggest unzipping the mattress cover and leaving it in a well-ventilated room for a few days while the smell completely dissipates.

My Final Thoughts about the Idle Hybrid Mattress

Now that we’ve learned all there is to know about the Idle Hybrid mattress, I want to recap some of my favorite things about it and my complaints. Though I can’t tell you if the Idle Hybrid is the right bed for you, I hope these final remarks will help you decide.

My favorite things about the Idle Hybrid mattress

Because of the low motion transfer and great edge support, I really like the Idle Hybrid for couples. I’d also recommend this mattress for back and side combo sleepers, as it offers nice mobility and a little bit of bounce, making it easy to roll around and switch positions during the night. Plus, the medium firmness offers appropriate support for those sleeping positions! The mattress is really durable. It’s flippable, something not every option on our best hybrid mattress list can say, and has a lifetime warranty. If you’re looking for something to last you a long while, this might be a great pick.

My Idle Hybrid mattress complaints

I found a lot to love about this bed and not too much to complain about! However, this particular bed lacks sinkage and body-contouring. For that reason, I wouldn’t recommend it for people who love that particular feel—a model with more memory foam layers might provide the kind of sensation you’re looking for!

Yes, the Idle Hybrid comes with a lifetime warranty! 

Does the Idle Hybrid mattress come with a sleep trial?

Yes, Idle offers you 18 months, or 540 nights, to try this mattress in your own home!

Well, it really depends. How long a bed will last depends on a bunch of things, including your body weight and your preferred sleeping position. The good news is that the Idle Hybrid comes with a lifetime warranty, and it’s flippable! If I had to guess, I think most people could get about 10 years of solid use out of this model. But obviously, your experience may vary!

Nope, no box spring is necessary!

Idle Hybrid Mattress Vs

So now that we have a pretty good idea of what’s going on in the Idle Hybrid, let’s take a moment to compare it to some of its biggest competition on the market. Below, I’m going to briefly compare the Idle Hybrid to two of its competitors: the Helix Midnight and the Casper Wave Hybrid.

Idle Hybrid vs Helix Midnight

Idle Hybrid vs Casper Wave Hybrid

  • While both beds offer pressure relief and support, the Casper Wave Hybrid has Airscape Foam to keep you cool and zoned support.
  • The Casper Wave Hybrid could be very beneficial to sleepers with back pain.
  • The Casper bed is a lot more expensive than the Idle, not too shocking as it is known as the brand’s luxury mattress.
  • To learn more about this bed, check out my full Casper Wave Hybrid mattress review.

Other Models from Idle

Wondering what else Idle has to offer? Below, I’ll share the three other mattresses from Idle. Let’s see how the Idle Hybrid compares to the Idle Gel Plush, the Idle Gel Foam, and the Idle Latex Hybrid!

Idle Hybrid vs Idle Gel Plush

  • If you couldn’t tell by its name, the Idle Gel Plush is a softer, more plush mattress with cooling qualities! 
  • The Gel Plush is designed with multiple soft foam layers, and no coils like the Idle Hybrid has!
  • The Idle Gel Plush does not have nearly as sturdy of edge support as the Idle Hybrid does. 
  • The price tags between these two mattresses are very similar.
  • To learn more, read my full Idle Gel Plush mattress review.

Idle Hybrid vs Idle Gel Foam

  • The Idle Gel Foam is an all-foam mattress and has more sinkage than the Idle Hybrid — making it a better mattress for sleepers needing deep pressure relief.
  • While both mattresses fall at a 6.5 firmness rating, they have quite a different feel due to their different builds!
  • The Idle Gel Foam has more cooling properties — something for hot sleepers to consider!
  • The Idle Gel Foam is much more affordable than the Idle Hybrid.
  • For more check out my full Idle Gel Foam mattress review.

Idle Hybrid vs Idle Latex Hybrid

  • The Idle Latex Hybrid is also a double-sided mattress, but incorporates latex foam rather than memory foam, giving it a more springy feel.
  • The Idle Latex Hybrid is a great choice for combination sleepers as the latex materials offer a ton of mobility.
  • The Latex Hybrid model is a bit more expensive than the Idle Hybrid, but probably not enough to weigh your decision one way or the other.
  • If you want more info on this model, head over to my full review of the Idle Latex Hybrid mattress!
