Sleeping Position Overview

The Idle 14in Foam mattress is a medium-soft mattress which would be considered comfortable by most people. However, if you sleep on your stomach consistently, you may want a firmer mattress, like the Idle Hybrid instead.

  • Back Sleepers: If you sleep on your back, you're most likely to like a medium to medium-firm mattress. The Idle Foam mattress is considered a medium mattress when it comes to firmness and should be comfortable for most back sleepers. It was great at keeping your entire body fully supported without any sinking feelings. 

  • Stomach Sleepers: If you sleep on your stomach, the Idle Plush Foam mattress may be too soft. The foam does sink when you lie on it, which may strain your back and neck if you sleep on your stomach. The Idle Hybrid or Latex mattresses would be better suited for this sleep style.

  • Side Sleepers: If you sleep on your side, you'll love this mattress. Its soft yet supportive, which is traditionally what side sleepers find to be the most comfortable. There's enough give in the foam to be able to conform to and support all areas of your body while you sleep.

Overall Build Quality/Quality of Materials

Edge Support

Idle isn't a cheap brand, but with mattresses, you get what you pay for. We were very impressed with the overall build quality of this all-foam mattress. 

It has 6 structural layers, as well as a washable cover, a fire-resistant base cover to protect the mattress no matter what happens. 

Nothing about this mattress felt cheap. Everything from the weight, to the foam itself, to the cover and the pillows that came with it, everything was a quality level that justified the price. It's a high-quality foam mattress that should last for years. 


There are a ton of all-foam mattresses on the market, and what makes each one unique are their layers. The Idle Plush foam mattress puts cooling support at the forefront of their design. Here's some info on the layers of this mattress.

  • "Ice Fabric" Cover: This cover is truly remarkable. It's noticeably cooler than a traditional mattress cover, and the cooling effect lasts throughout the night. 

  • 1" Cooling Buoyancy Foam: Another cooling layer, this buoyancy foam is designed to feel like traditional foam, but without that "stuck" sensation. It's more responsive, which means it takes the shape of what's put on it, but once you get up/remove the object on the bed, it bounces back quicker than traditional memory foam. 

  • Fire Resistant Barrier: This layer is a 100% natural cotton barrier than shields the bed from potential fire damage in the worst-case scenario.

  • 3" Gel Infused Buoyancy Foam: This support layer is what provides the quick reaction time and support of this mattress. 

  • 3" Idle Memory Foam: The next foam layer of this mattress provides additional support and thermal neutrality which means it's more responsive and retains less heat than traditional foam. 

  • 8" High-Density Foam Base: This super-thick base provides extra stability and is one of the main reasons why the Idle foam mattresses are thicker than the industry standard. It's also around 30% more durable than other types of foam due to its super high density.

  • Fireproof Cloth: This layer is another fire-resistant one that helps in case of emergencies. It has no petroleum-based synthetic nylon or polyester either. 

  • Washable Base Cover: The final layer of this mattress is a washable cover that unzips so you can easily clean it.

All of these layers come together to create a 14in foam mattress, which is thicker than most others within the same price range on the market.

Overall Comfort & Pressure Relief

Comfort is the #1 thing you should consider when shopping for a mattress. After all, if a mattress isn't comfortable, it doesn't matter how many layers or cool features it has, you won't like it. 

We're happy to tell you that the overall comfort level of The Idle Plush Foam Mattress was great. 

I'm a lightweight combination sleeper, and I was able to get comfortable in multiple positions. This mattress had enough support for my spine and neck while lying on my back. It provided good pressure relief for the hips and shoulders when lying on my side; yet it was still firm enough not to cause a kink in my neck while sleeping on my stomach.

Overall, the comfort and pressure relief level was great. The only area that Idle Sleep could improve on would be edge support. Edge support with all-foam mattresses is always tough to get right, but it was the only real comfort flaw of this bed.


According to Idle, this mattress comes in at around a 4.5-5.5 on the firmness scale. This makes it a true medium, but for heavier sleepers, it may feel softer.

For me, someone weighing well under 250lbs, it felt like a true medium. However, without additional support coils like you'll find in their hybrid, if you're heavier, it will definitely feel softer. 


Motion Isolation & Motion Transfer

All-foam mattresses are known for having great motion isolation, with a minimal amount of motion transfer, and this mattress was no different. As you can see, you can make a fair amount of ruckus on the bed without knocking over a glass of water. Nice!

Cooling Properties

It felt like the entire build of this mattress was centered around keeping you cool at night. The cover itself provides a cooling effect to the touch while the buoyancy foam layers help dissipate heat throughout the night while you sleep. 

Overall, if you're a hot sleeper, this mattress makes a huge difference in how cool you stay at night.

Idle Talalay Latex Hybrid Mattress Review

Idle Talalay Latex Review

The next mattress up for review is Idle's premium Talalay latex hybrid mattress. The organic latex has a springier feel than foam, and offers extra cooling features, but does also feel firmer overall even though it has the same firmness rating. Here's a quick overview of what we thought about this mattress.

Quick Summary:


  • Coils in the center give it a springy feel and helps improve longevity
  • Two sided with variable firmness options
  • Firm support that's great for back and stomach sleepers
  • Lifetime warranty
  • 18 month trial period (industry-leading)
  • Free shipping and returns


  • The "medium" for the latex model is notably firmer than the "medium" of the all-foam bed. 
  • Larger investment

Sleeping Position Overview

If you're a stomach or back sleeper who prefers a slightly firmer feel, this mattress is a incredible. It's one of the better medium-firm mattresses we've tested. However, if you like a softer feel, or sleep on your side, it won't be a great choice. 

Back Sleepers: If you're a strict back sleeper, the support this mattress provides will feel great. You feel more like you're sleeping "on" the mattress instead of "in" the mattress like you get with the all-foam bed. 

Stomach Sleepers: Stomach sleepers will love this bed more than any other sleep style. Since you need a very flat surface with minimal give to keep your spine aligned while you're sleeping on your stomach, the Talalay latex's naturally firmer feel is a great match. 

Side Sleeper: If you sleep on your side, this mattress will most likely be too firm. Sleeping on my side on this mattress almost instantly gave pressure points in my shoulders and hips. Side sleepers will like a bed that has more give.

Build Quality & Materials

The overall build quality of the Idle Talalay Latex mattress was superb. Everything from the stitching to the springs felt premium and long lasting. Not unlike the all-foam mattress, the Idle Talalay Latex mattress has multiple layers, each providing a unique comfort factor that contributes to the overall feel of the bed. 

One thing we did notice that needs to be mentioned is that this bed is HEAVY. In fact, a queen size had to be delivered via FedEx freight. Latex is a heavier material so you'll need at least two strong people to properly set up the mattress. If you're older, or live alone, white glove delivery (done for you set up) is highly recommended.

However, one great thing about this mattress is the carrying handles it has on the sides. Since it's a heavier mattress, these handles make the bed MUCH easier to move around.

Carrying Handles

While this bed may feel like a larger up-front investment, a latex mattress will last longer than a foam one will. This bed could very well last 25+ years with proper care, as opposed to the standard 5-10 years of a lower cost alternative.


If you're curious to know exactly what this mattress is made of, here's a quick summary of all of the layers that make up the Idle Talalay Latex Hybrid mattress.

  • Layer 1 - Cover & Yard Rosettes: The first "layer" is the cover on the mattress. It's an all natural organic cotton that's wrapped around the entire mattress. It provides great airflow for a cotton cover and is more eco friendly and healthy because it's held down with soft yarn rosettes rather than glue.
  • Layer 2 - Wool Transition Layer: Right under the cover, there's 1" of natural wool quilted into the cover. This adds extra softness and comfort, and also provides a transitional barrier between you and the following latex comfort layers.
  • Layer 3 - 100% Latex: This is where things get interesting. Idle has a generous 3" of 100% Talalay latex as the next layer. Talalay latex is open cell and very breathable. It also has anti-microbial properties which makes it great if you're worried about the longevity of the mattress. 
  • Layer 4 - Coil Support: The next layer is the edge-to-edge pocked coils. These coils give the mattress a more traditional feel and springiness. They also give the mattress its responsiveness and aid in promoting good airflow.
  • Double Sided: The following layers are an exact replica of the layers above, but in reverse. This makes the mattress 100% flippable and able to be used whether its rightside up or upside down.

Comfort, Pressure Relief & Edge Support

We tested this mattress with a back sleeper, stomach sleeper and side sleeper. The back and stomach sleepers both absolutely loved the mattress. Pressure relief for the lower back and neck was noticeable right away. However, the side sleeper felt differently. If you sleep mostly on your side, this mattress won't offer good pressure relief. In fact, if you're lightweight (under 200lbs) and sleep on your side, the mattress may actually create new pressure points.

While this bed is great for back and stomach sleepers, it's also worth noting that is has excellent edge support. Since it has edge-to-edge coils, you get just as much support on the edge of the bed as you do near the center. This is great for couples who share a smaller bed.

Edge Support


The Idle Talalay Latex Hybrid is rated as a medium, but we found it to be firmer than most other medium mattresses we've tested. Since you have the option of either a medium or luxury firm, keep in mind that the luxury firm should be reserved for those who love a very hard bed with very little give. 

Just like in Idle Hybrid, the Latex Hybrid is flippable, and you can customize your firmness level on either side. If you're unsure if the medium will be firm enough for you, you can get one side medium and one size luxury firm. 

Overall, this mattress in the medium level comes in at around a 7/10 on the firmness scale.

Talalay Firmness and responsiveness

Motion Isolation

A hybrid mattress like the Talalay Latex hybrid mattress is always going to have some motion transfer. Since the core of the bed is made out of springs, it's going to be more responsive, but also transfer more motion. As you can see, the motion isolation wasn't nearly as good as the all-foam bed, but still decent for a hybrid style mattress.

Cooling Properties

Latex is generally a cooler material to make a mattress out of. However, the organic cotton cover offsets this. Yes, the mattress is breathable, but it's no cooler than the all-foam bed with the cooling cover. 

The springs and open cell latex offers good overall cooling, but it wasn't as dramatic of an immediate effect as the all-foam with the cooling cover. However, it did hold a consistent temperature throughout the night, whereas the all-foam with the cooling cover got warmer over time as it absorbed body heat. If you're specifically looking for a cooling mattress, this one is good, but not great.

Buying Experience

Buying a mattress online can be scary. It doesn't matter how many reviews you read; you never truly know how you're going to like a mattress until you sleep on it. 

The industry standard for an in-home trial is about three months, with some companies offering free returns, and others requiring a restocking fee. 

The industry standard for a mattress warranty is about ten years. 

Idle blows these numbers out of the water. They offer an 18 month trial time period and a lifetime warranty with free returns. As far as risk-free online mattress shopping goes, this company is a leader. One other thing to note - you also get free shipping and returns if you end up not liking the bed.


Overall, we don't have much bad to say about the Idle Plush Foam Mattress or the Idle Talalay Latex Mattress. They're both made  with care and are a great choice for different situations. Idle's trial period, return policy and warranties are unmatched, making them a great option when it comes to buying a bed online.

    1. As long as the frame is a standard size for a CA king, it should be fine, but Idle has incredible customer service, and you should be able to get on chat with them to make sure. Check out their site here if you want to make sure.
