Are you looking for a mattress that provides soothing pressure relief while keeping you cool all night long? If so, consider the Idle Gel Foam mattress! Its soft foam comfort layer is infused with a cooling gel to keep you from overheating. And for support, the Idle Gel Foam offers sturdy layers of polyurethane foam and high-density polyfoam.
So what’s all the hype about this mattress? To find out, I’m going to put it through a series of tests and see how it performs on things like pressure relief, motion transfer, and edge support. I’ll also check out its firmness level and construction.

Founded in 2017, Idle Sleep’s mission is to create a luxurious sleeping experience. Based in the USA, the company sells a full line of mattresses (four in total), as well as bed sheets, pillows, and more.
Later on, I’ll see how it stacks up against three of Idle Sleep’s other mattresses: The Gel Plush, the Hybrid, and the Hybrid Latex. But first, let’s see what goes on inside the Idle Gel Foam!
What is the Idle Gel Foam Mattress Made Of?
The Idle Gel Foam mattress is built with what they refer to as “Cooling Buoyancy Foam,” a material that — much like memory foam — offers a pressure-relieving, contouring feeling. And thanks to the transition and foundation layers, you’ll feel some support while you sleep.
What intrigued me about the Idle Gel Foam is that it uses three layers of foam, all with varying degrees of firmness. Taken together, you’ve got a plush, yet durable mattress surface. Not to mention that it uses a cover and comfort layer with cooling properties to help prevent you from getting too warm at night.
To give you a closer look at these materials, let’s check out each layer!
Cover – To kick us off, we have a thin, breathable cover that helps you stay cool. And since it’s machine washable, keeping it clean should be a synch.
Comfort Layer – Next up is a 3” layer of Idle Cooling Buoyancy Foam. Infused with cooling gel, it has a slow response to pressure, just like memory foam. This helps alleviate tension as you sink into it. But since there’s not much bounce to this material, you may feel a little stuck as it contours to your body.
Transition Layer – After this, we come to a 2” transition layer of firmer polyurethane foam. Since this foam has a quick response to pressure, you won’t sink into it much. This layer is meant to ease you into the firmer foundation layer below.
Foundation Layer – Finally, we have a 7” layer of sturdy high-density polyfoam. This is a really firm material that a lot of other bed-in-a-box mattresses use for support.
What Does the Idle Gel Foam Mattress Feel Like?
So do all of these materials make up a comfortable mattress? To find out, let’s first check out its firmness.
You should know that firmness isn’t a one-size-fits-all scenario — your size, weight, shape, and other factors all determine your ideal level of firmness. So your preferences might not be the same as mine. For reference, I’m 5’10”, weigh 190 lbs., and prefer to sleep on my stomach.
After lying on the mattress, I put the bed at a 6.5 out of 10 on the firmness scale, with 10 being the firmest. I would say that’s about the industry standard for a medium-firm mattress, the Idle Gel Foam is right around that mark.
The slow response to pressure from the comfort layer gave a ton of great pressure relief when I tried it on my back and side. I think back sleepers and side sleepers are especially going to enjoy this. And the cooling features help keep it from trapping body heat, which is a common problem with foam mattresses.
On the other hand, I don’t think this mattress is great for combination sleepers. I felt a bit stuck in the mattress when swapping positions, since it doesn’t give a bouncy feeling. Also, I think stomach sleepers are going to want something firmer than this for support.
Testing the Idle Gel Foam Mattress
Firmness shouldn’t be the only factor that comes into play when choosing a mattress. Three other factors worth considering are pressure relief, motion transfer, and edge support. I put all of these factors to the test, and I’m pumped to share my results with you!
First up is the pressure relief test. A mattress with good pressure relief will help alleviate tension at the shoulders, hips, and lower back.
To get an idea of how well the Idle Gel Foam does at handling pressure relief, I used my handy pressure map device. By putting the pressure map on top of the mattress, I was able to see where pressure was relieved and where it wasn’t. For reference, blue means low pressure and red means high pressure.
Back – I think this is a great mattress for back sleepers. My weight was evenly distributed when I was on my back, so I felt a relaxing mix of comfort and support. This was all thanks to the contouring feel of the comfort layer and the supportive feel of the lower layers.
Side – Once I rolled to my side, I felt some nice pressure relief at my hips and shoulders. As the pressure map shows, there was a slight amount of pressure at my shoulders, but it wasn’t enough to cause me discomfort. Generally, I recommend side sleepers go for something a bit softer like this to avoid tension from building up at their shoulders and hips. So overall, I think side sleepers will be really happy with this mattress.
Stomach – After switching to my stomach, I didn’t feel enough support at my hips and torso, despite the blue on the pressure map. Typically, I recommend stomach sleepers go with a firmer mattress to keep their shoulders in line with their hips and their spine aligned. With that in mind, I don’t think this mattress is going to be the best fit for stomach sleepers.
Next up is the motion transfer test. Basically, this refers to the amount of noticeable disturbance from one end of the mattress to the other. How well a mattress does with motion transfer can be really important if you share a bed, especially if your bedmate is a restless sleeper.
To test out the Idle Gel Foam’s motion transfer, I dropped a 10 lb. steel ball onto the mattress from three different heights. The 4” drop simulated tossing and turning in the bed, the 8” drop simulated getting out of bed, and the 12” inch drop simulated how it would feel if my bedmate wanted to jump on it.
I then reviewed the results from each drop. For reference, bigger lines equal more disturbance.
I think the Idle Gel Foam isolated motion pretty well. While there were some initial high spikes of disturbance for each drop, the soft foams helped to tamp it down quickly. This might be an issue if you’re a light sleeper, but for people who aren’t as easy to wake up, this shouldn’t be a problem.
The final test deals with edge support. I looked at the Idle Gel Foam’s edge support to determine if it’s likely to hold up when you sleep toward the end of the bed. Also, if you ever sit on the side of your bed, such as when putting on your shoes in the morning, you’ll probably want to consider a mattress with strong edge support.
To test out the edge support, I rolled to the end of the bed to see if it would collapse. I’m pleased to report that the edge support was sturdy enough to keep the mattress from caving in.
Since it offers decent edge support, the Idle Gel Foam lets you use all of the available space, making it feel that much bigger. This might be good if you decide to go with the full or queen models and want to make sure you can use the entire mattress.
Other Idle Mattresses
Like I mentioned earlier, Idle Sleep makes three other mattresses. With that in mind, let’s see how it compares to the Idle Gel Plush, the Idle Hybrid, and the Idle Latex Hybrid!
Idle Gel Plush
- I’d say this mattress is a bit softer than the Idle Gel Foam, thanks to its thicker layers of memory foam that let you sink in more.
- While the Idle Gel Foam does a swell job with pressure relief, I think the Idle Gel Plush performs better in this area due to its thicker layers of soft foam.
- Unlike the Idle Gel Foam, the Idle Hybrid uses a layer of pocketed coils for support along with foam layers for softness — this is what makes it a hybrid mattress.
- I think the bounce of this medium-firm mattress is much better than the Idle Gel Foam for back/side combination sleepers, since it allows for greater mobility when changing positions.

Idle Latex Hybrid
- I think the Idle Latex Hybrid’s coiled layer makes it a bit firmer than the Idle Gel Foam, which means you won’t get as much pressure relief from it.
- Unlike the Idle Gel Foam, the Idle Latex Hybrid has some bounce to it. This gives it an “on-top-of-the-mattress” feeling, which is good news for combination sleepers who switch positions at night.

Well folks, it’s now time to answer the all-important question: Is the Idle Gel Foam the best mattress for you? To help you decide, check out my final thoughts!
Idle Gel Foam Pros
- I think back sleepers are really going to dig the pressure relieving capabilities of this mattress! And the firmer bottom layers will likely give them the support they want.
- I also think this is a fantastic choice for side sleepers! Since it alleviates tension well, it will likely help them avoid shoulder and/or hip pain.
- I think this mattress is likely going to help you sleep through the night without breaking a sweat, thanks to its breathable cover and cooling gel-infused comfort layer.
Idle Gel Foam Cons
- I don’t think stomach sleepers are going to like its level of support. I think they’re likely to feel their hips and spine sink in uncomfortably deep, due to its soft comfort layer.
- Since there’s not much bounce to this mattress, you might feel a little stuck if you change positions throughout the night. This could be a problem for folks who like alternating positions.

You do not need a box spring with this mattress, but you can use one if you want. This mattress will work well with most types of foundations.
Can you flip the Idle Gel Foam?
You should not flip this mattress. Idle Sleep has made it to be felt in a particular way, with the comfort layer at the top and the supportive layers at the bottom. So flipping it would probably be quite uncomfortable.
