Is the IDLE Sleep Hybrid Mattress Right for You?

Buy the IDLE Sleep Hybrid mattress if you like:

  • You are looking for a mattress suitable for all sleeping styles – The IDLE Sleep mattress provides two firmness options, a medium firm model with good support for all sleeping styles and a higher degree of bounce and responsiveness and firmer model that provides IDLE provides better support for back and stomach sleepers, as well as for heavier sleepers.
  • Mattresses that sleep cool – The Thermocool infused top layer and the IDLE Air Flow foam and IDLE Cooling Buoyancy foam, combined with the innerspring coil layer which by design provides good airflow and discourages heat retention, all make this bed sleep rather cool.
  • Classic memory foam feel – The top foam layers of this mattress will provide that classic memory foam feel of hugging and contour and excellent pressure relief, but they won’t cause you to sink too much into the bed and feel enveloped by it.
  • Durable beds – A unique 2-sided design of the IDLE Sleep Hybrid, which gives you the possibility to flip it over from time to time, allows even wearing and increases the durability of this mattress.

You might not like the IDLE Sleep Hybrid mattress if:

  • You don’t like the bounce and responsiveness of hybrid mattresses – The IDLE Sleep Hybrid mattress is a coil/foam hybrid which has a lot of bounce and responsiveness and if you don’t like buoyant mattresses that are likely to cause a little motion transfer, this mattress may not be the best choice for you.

Construction and Materials – What is the IDLE made up of?

The IDLE Sleep hybrid mattress is a 14″ hybrid pocketed coil and foam mattress made up of 7 layers, with the top comfort layers which are basically duplicated when flipped over.

  • 1″ Top Comfort Layer – This layer is 1″ of IDLE quilting foam that is sewn into the top layer and designed to provide softness and comfort to the top layer of the mattress.
  • 1″ Comfort & Response Layer – This layer is 1″ of IDLE air flow response foam designed to provide cooling as well as responsiveness and bounce to the mattress.
  • 2″ Cooling & Pressure Relief layer – This layer is 2″ of IDLE Cooling Buoyancy foam, a custom blend of foam that promises 4x better pressure relief than traditional memory foam and also helps provide more cooling to the mattress.
  • 6″ Support Layer – This layer is 6″ of Quantum edge-to-edge high quality steel pocketed innerspring coils sandwiched between  that act as the core support to the mattress and provides deep compression support with great edge support.
  • 2″ Cooling and Pressure Relief layer – same as the top layers
  • 1″ Comfort & Response Layer – same as top layers
  • 1″ Top Comfort Layer – same as top layers

The cover of the IDLE Sleep hybrid mattress is infused with Thermocool – a material that aids in heat dissipation and acts as phase-change temperature regulating material that cools you when you’re warm, and warms you when you are cool.

The cover has a nice pattern on it that feels good and has the Thermocool foam quilted within it which aids in comfort and airflow.

Dual Sided Design

The IDLE Sleep hybrid mattress differs from almost every mattress on the market these days (or at least bed in the box models), in that it has the ability to be flipped over and help prevent body indentation and softening up of the bed over time.

Most of the flippable beds we have tested have a different firmness on each side, which at first we thought this bed provided, but instead – IDLE differentiates their offering by having the SAME firmness on each side, so thereby allowing you to flip and rotate your bed like a traditional mattress you may be used to.

This will help extend your mattress life and also prevents any indentations or sagging from occurring if you or your partner is heavier than the other, by enabling you to flip and rotate the bed – preventing any of this from happening.  A first among mattresses we have reviewed for sure!

IDLE also offers you the ability to have different firmness options on each side (Medium on one and Luxury Firm on the other), but this makes it single sided actually, if you don’t flip it over. 

Firmness & Support of the IDLE Sleep hybrid mattress

The IDLE Sleep hybrid mattress comes in 2 different firmness options, Medium and Luxury Firm. We tested the medium firm model, and rate it around a 6.5 out of 10 (10 being firmest). The company says it is more of a 5.5 / 6, but in our experience, and like many hybrid models, it feels firmer.

IDLE mattress firmness

Over time, possibly the mattress may soften up, but initially with the hybrid coil construction we feel it is on the firmer end of the medium spectrum.

The IDLE Sleep mattress feels a little firmer to me, as I am significantly heavier than Kaye, and I tend to press through the top comfort layers and feel more of the support layers in most mattresses.  Most hybrid models feel firmer to me for this reason.

The nice 14″ thickness of the IDLE Sleep hybrid mattress with its high quality pocketed coil support layer helps support both my heavier 230lb weight and combined weight with Kaye.

So in terms of support, the IDLE mattress does a really good job of providing excellent support in all sleeping positions, with the top memory foam comfort layers providing body hug and contour with the underlying spring support layer providing the deep compression support for the body.

Since Kaye and myself are primarily side sleepers, we like mattresses that provide enough give in the top comfort layer to support our shoulders and hips, while also having the firmness if we switch to our stomachs and backs. The Medium version of the IDLE is most likely much more suited for this compared to the Luxury Firm model.

Having a mattress that is too soft causes the spine to be misaligned and results in pain, but the IDLE prevents this with the use of the pocketed coil support layer and the multiple layers of foam in the top comfort layers.

The IDLE hybrid really provides the degree of support a heavier sleeper like myself needs from the pocketed coil foundation layer combined with the dense foam top comfort layers, and the 14″ thick design contributes to this quite a bit.

This is a welcome change for us, as we get quite a few of the thinner 10″ models which just can’t support my heavier weight or our combined weight as a couple.

Back sleepers and stomach sleepers will most likely find the Firm version of the IDLE Sleep good for those styles as well, as it is firm enough to provide support and comfort for those sleeping styles without being too soft and causing excessive sinkage.

How is the comfort on the IDLE hybrid mattress?

Most hybrid mattresses are designed to provide the “best of both worlds” feel of the bounce and support of innerspring coils along with the body hug and contour of memory foam.

The IDLE bed is no different in this regard, and provides exactly that – a nice thick innerspring bed with the support that design is known for, along with the upper foam comfort layers which provide the comfort and body hug that memory foam is known for.

We are big fans of memory foam personally, as we like the feel of “sleeping in” a mattress, compared to the feel of “sleeping on top of” which many latex and hybrids are known for.

While the IDLE does a good job at providing a comfortable sleeping surface, being that is is a hybrid with the majority of its construction being pocketed coils, it gives the bed more of that buoyant, bouncy feel that coils are known for.

The hybrid construction with the pocketed coil support layer provides the expected bounce and the foam mattress top layers provide good body contour and hug, but not as much as an all-foam mattress provides.

If you are looking for significant body hug and contour, the IDLE Sleep hybrid may not be the right choice for you, and you may need to try their all-foam model. If, however, you like the bounce and responsiveness that coils mattresses are known for, but with the added comfort layers of foam, you may like the IDLE Sleep hybrid mattress.

After sleeping on this mattress for a while, we found that our bodies adapted to the mattress and molded to the memory foam without feeling stuck or trapped in the foam. The coils helped provide the bounce needed to switch positions during the night and supported my heavy body weight with ease.

The IDLE Sleep hybrid mattress is also great for sex as well, with the bed providing good push-back and bounce needed for sex without feeling trapped in foam as previously mentioned.

The cooling technologies in the mattress (explained below) also do a great job at preventing heat buildup or that “sticky sweaty” feel that some all-foam mattresses cause you to feel. A big plus if you sleep with a partner!

Sleeping Hot – not on the IDLE Sleep Hybrid

All the various cooling technology in the mattress makes the IDLE Sleep hybrid mattress sleep rather cool. The Thermocool infused top layer as well as the IDLE Air Flow foam and IDLE Cooling Buoyancy foam, combined with the innerspring coil layer which by design provides good airflow and discourages heat retention, all contribute to helping this bed sleep much cooler than many models we have tested.

Sleeping hot is a big pet peeve of ours, and is something that many all foam mattresses struggle with.  The IDLE Sleep mattress, however, solves this issue by the use of the cooling technologies we listed above.

We didn’t wake up feeling hot and sticky during the night, which for us living in Texas and sleeping as a couple, have had issues with in the past with other beds.

The combination of this material with the coil and foam construction used in the mattress does a great job of ensuring the mattress sleeps cooler than most mattresses we have reviewed.

Sinkage & Motion Transfer on the IDLE mattress

The IDLE Sleep hybrid mattress does an good job with sinkage, especially compared to most mattresses we have reviewed. As we always preach, sinkage (and motion transfer) is largely weight dependent.  We say this a lot, but it really is true. Thicker beds such as the IDLE, with their 14″ design, do a lot better in this regard than the thinner 10″ models we have reviewed.

The fact that I weigh around 230lbs tends to have a rather large bearing on the degree of sinkage I experience when sitting and lying on a mattress, something that my partner Kaye doesn’t experience.

Because of my heavy weight, on most mattresses I tend to cause them to compress down quite a bit when sitting on the edge, or sitting upright in bed.  Kaye, being half my weight, experiences much less sinkage than I do as she doesn’t compress down on beds.

With the IDLE mattress, however, this isn’t a problem at all due to its thick 14″ design and high quality coil construction along with layers of foam that helps minimize sinkage quite a bit.

Idle Sleep hybrid profile

Edge support is very good with this mattress as well, and better than many mattresses we have reviewed – due to the edge-to-edge Quantum Coil design of the mattress.  I tested this by sleeping near the edge at times and did not experience any of the “rolling off” the edges or having them compressed under my weight.

Motion transfer, however, is more than most all foam mattresses we have reviewed, and is to be expected with a hybrid coil mattress which provides more bounce than a foam mattress due to the innerspring coils in its construction.

It wasn’t too significant, but the bounce from the springs did cause some shaking of the bed when I got in and out of it during the night or changed positions. Not too much of a deal breaker, but it was present.

Smell / Off-Gassing? Not with the IDLE Sleep Hybrid!

The IDLE Sleep hybrid mattress gets high marks in this category for not having a noticeable smell upon opening the box. The hybrid coil / foam construction minimized the degree of off-gassing that all foam mattresses usually have.

Off-gassing is often a problem for many all-foam beds when compressed and shipped in a box, but thankfully this isn’t the case with the IDLE.

IDLE Sleep’s Customer Service

IDLE Sleep really shines in the customer service department by offering some options that are far above the standard service offerings that most bed-in-a-box online mattress companies are offering these days. This includes the following:

The IDLE Sleep is one of the few mattress companies that offer a lifetime warranty for their mattresses, which will help you feel better about your purchase, knowing that it is supported for the life of the mattresses.

Besides this, the company offers incredible 18 Full Month Home trial which is the longest sleep trial in the industry ever! The company gives you the possibility to sleep on their mattress for more than a year and if you are not satisfied with it, you can return it and get your money back. This is definitely a huge bonus that can help you evaluate the product better and make sure it fits your needs.


The IDLE Sleep hybrid mattress is price very affordable compared to most beds we have reviewed, coming in at $994 for a Queen, which is a great price given the quality materials and construction used in this mattress.

Twin XL$774
Cal King$1294

The IDLE Sleep hybrid mattress is a great hybrid coil / foam mattress that provides the benefits of both innerspring mattresses and memory foam mattresses as well as the option to flip the mattress over and extend its life.

The IDLE Sleep hybrid mattress provides two firmness options, a medium firmness mattress with good support for all sleeping styles, and provides a higher degree of bounce and responsiveness from the coil hybrid design. If choosing the firmer model, the IDLE provides better support for back and stomach sleepers, as well as for heavier sleepers.

The hybrid coil and foam design is great for providing excellent support, and while this makes the mattress have more motion transfer, this is to be expected for these type of mattresses.  Sinkage is minimal due to the thick 14″ design, and edge support is quite good.

The IDLE sleeps cool due to the use of various cooling technologies in its cover as well as in the foam layers. The innerspring pocketed coil construction also helps prevents heat buildup. The cooling features as well as good support makes it a great mattress for couples as well as those that like the bounce of innerspring mattresses and the hug and contour of foam.

All in all, the IDLE Sleep hybrid mattress is a great bed that comes in at more than a reasonable price given the materials used in its construction and for the fact you basically get “two beds in one” due to the flippable design which extends its life and helps prevent indentation and sagging.

Besides this, you will get a lifetime warranty for the IDLE Hybrid mattress and incredible 18 Full Month Home Trial, which is the longest sleep trial in the industry!

  1. I like having the support of coils over just a foam mattress

  2. I think Idle Mattress is a great mattress because I love traditional innerspring mattress and this mattress has that as well as memory foam so would have the best of both worlds! And I also love the fact that it is flippable! This sounds like a mattress I would love to own!

  3. I like the combo of traditional innerspring mattress and memory foam. Impressive.

  4. I love the idea of a Hybrid Mattress and this sounds like a great one. Since I tend to be very hot at night I love that this mattress has the Thermocool infused top layer to help with this.

  5. I love the traditional coils are built into this mattress for extra support.

  6. I tend to get very hot when I sleep so the Thermacool feature is definitely a plus.

  7. I think the fact that the cover of the IDLE Sleep mattress is infused with Thermocool is a really great concept. I also like that it has the same firmness on both sides.

  8. Innerspring coils? Memory foam? Cooling technology? Flip for extended life? Prevention of sagging and indentations? Have I arrived in a mattress Dreamland? This sounds like the perfect mattress for me and everyone! Amazing benefits! My current mattress is an abomination so this one has all the points I look for in a new mattress plus more! As a product tester, I would be grateful to receive, test, review and share my experience with the mattress throughout social media. Thank you for the fabulous review and for the chance to have the best night’s sleep ever.

  9. My husband and I like different temperatures when we sleep, so the Thermocool cooling technolgy is such an amazing feature. The memory foam makes for a great addition to make it feel like you are truly sleeping on a high-end 4 star hotel mattress. This is a dream matters and all these features make it a perfect combination for an amazing sleep.

  10. I love the cooling aspect of the Idle. I also appreciate the ability to flip it.

  11. Great review! We are looking for a new mattress and this helps. I like the fact it has Thermocool which is very important for us because I’m always hot and he’s always cold. Plus I like the fact that it’s flipable because I think this will make the mattress last longer.

  12. I’m loving this Idle Sleep Hybrid Mattress! Love that it’s a 2-sided mattress, not very common in a hybrid mattress, but I think it’s the way of the future in the hybrid mattress industry! The 14″ mattress itself is nice! Love the cooling coils, and the cover that keeps you cool when you’re hot, and warm when you’re cold…. VERY NICE!!!! I’m a hot sleeper, and the hubby is always cold so this would truly be the perfect mattress for us! The Idle Sleep Hybrid Mattress would be a true dream come true for us! Thanks for the great review… lots of good info!!!

  13. One of the best things that I can see with this mattress is the fact that it can be flipped. I have missed that with my current pillow top mattress.

  14. I love that it can be flipped. That’s one thing I really don’t like about my current mattress.

    • Not many mattresses these days can be flipped, the IDLE is one of the few ones that can be…

  15. I Love that it’s flippable to help prevent sagging, that it has both coils and memory foam, and that it has motion transfer. Sounds like a mattress I would love.

  16. I wish the same reviews could be done after sleeping on the mattress for a couple of years. Everything works when it’s new.

    • Not a lot that can be done given some of these beds JUST came out. We have done that with Loom & Leaf and Nectar actually.. Loom and Leaf we updated after 2 years, and they are still one of our top picks. Nectar we evaluated after a year, and they are still our #1 choice and the bed we sleep on. So some of these you just don’t have a chance as they just came out.

  17. Great mattress, thank you for your review, it gave me all the information I needed to make my decision. I can’t wait to receive my mattress and sleep through the night for the first time in a long time.

  18. I love that you can flip it over, I didn’t think about that when I purchased my last mattress and I wish I had. I feel like I’m only getting half the life out of my mattress by having a pillow top. It’s also great that it has thermocool since my husband is a night sweater.

  19. Those are really high ratings! I love the idea of having the comfort of memory foam, yet not abandoning the idea of springs. There seems to have been a lot of research put in to the creation of this mattress. There are so many important, various layers!

  20. I really like that there’s a strong support layer. That seems to me to make this hybrid the best of both worlds.

  21. Question: Would it be possible to get this mattress made with left half of the mattress in medium firmness and right half in luxury firm?

    • They don’t make custom configurations to my knowledge.. that is usually reserved for other brands such as Helix Sleep. If that’s what you’re interested in, I suggest you configure a mattress from Helix or a customizable company..
