Idle Hybrid Mattress Review

The Idle Hybrid mattress is a mattress-in-a-box model built with both contouring memory foam and individually wrapped coil layers. It’s also a flippable model, which means you can use both sides of the mattress. It comes in two different firmness levels, and has a bouncy but supportive feel. Plus, one model allows you to switch back and forth between both of the two different firmness levels

I researched this model and did a bunch of tests like a pressure map test and a motion isolation experiment, to get all the details you need to know. Read on to learn more about the Idle Hybrid, and whether it’s a good selection for you and your needs.

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” 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 – The comfort layer consists of 2” 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 – Next up comes 1” 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” 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.

How Does the Idle Hybrid Mattress Feel?

After evaluating the materials, I tested out the bed to see how it feels. 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 6.5/10 on the firmness scale (1 meaning 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.

Due to the firmness rating, I think this is a nice model for all sorts of sleepers. On my back it provided a mixture of firmness and comfort, and kept my spine in a nice alignment. The pocketed coils offered a little bit of bounce, so I didn’ feel “stuck” when I tried to change positions by rolling around. So if you are a back and side combo sleeper who rolls around at night, you might like the feel of this model.

If you are a super strict side sleeper who prefers a plush feel, this might not be the best pick for you. That said, the mattress did provide some nice comfort on my shoulders and hips! Generally, I recommend that stomach sleepers go with a firm model so that their hips don’t sink too far down into the mattress and move their spine out of alignment.

Testing the Idle Hybrid Mattress

Firmness is just one thing to consider when you’re picking out a new bed. I tested this model to see how it performs in terms of pressure relief and motion isolation, which helped me get more info on the mattress to narrow down who I would recommend it for.

Pressure Relief

Instead of just going by feel, I like to run some specific tests to see how each mattress performs. For the first test, I roll out a pressure map on top of the model, then lie down on that in different positions. The device creates a colored map showing pressure, which ranges from blue in areas of low pressure through to red in high-pressure areas.

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

Back – The pressure map shows blue across the board for this one, suggesting that the Idle Hybrid offers great pressure relief for back sleepers.

Side – When lying on my side, the pressure map shows that my shoulders go a little bit into the green range. In my opinion that’s okay for a lot of side sleepers, but it’s not ideal for very strict side sleepers who might want something softer on their shoulders. This is also relevant if you have shoulder or upper back injuries!

Stomach – As you can see, my weight was evenly distributed when I lay down on my stomach. The pressure map is blue across the board. 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. Generally, stomach sleepers do better with a firmer mattress to keep their spine in alignment.

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 10lbs steel ball from heights of four, eight, and 12 inches onto the top of the mattress, and measured the disturbances using a seismometer.

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 can recommend it for couples or people who share their bed with pets based on these motion isolation results.

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 usually an important consideration for couples or people with larger bodies, 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.

Should You Buy the Idle Hybrid Mattress?

The Idle Hybrid is a medium firm mattress in a box that has a nice support level for back and side sleepers. The strong edge support and motion isolation make it a good choice for couples.

Idle Hybrid Pros

  • Because of the low motion transfer and great edge support, I really like the Idle Hybrid as an option for couples.
  • I’d also recommend it for back and side combo sleepers. The model 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 seems really durable. It’s flippable and has a lifetime warranty, so if you’re looking for something to last you a long while, this might be a great pick.

Idle Hybrid Cons

  • I personally found that this mattress sleeps a little bit hot. So if you tend to overheat at night and you’re looking for something with really excellent cooling technology, this may not be the ideal selection for you.
  • This particular bed lacks a sinking, body contouring feeling. 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!

FAQs

I also wanted to address some common questions we get, which don’t always fit into our standard review.

Can you flip Idle Sleep Mattresses?

You sure can! These beds are designed to flip, so you can flip the Idle Hybrid seasonally or on whatever schedule you choose. This can help reduce any sagging in the mattress, and help the model last for a little bit longer than a non-flippable bed.

How long will the Idle Sleep mattress last?

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!

Does the Idle Sleep Mattress need a box spring?

Nope, no box spring is necessary!
