Idle Gel Plush Mattress Construction

Idle Gel Plush Mattress Layers

The Idle Gel Plush mattress’s all-foam construction is both soft and supportive. It has the close, contouring feel of memory foam, which will make you feel surrounded by warmth and softness without the feeling of sinking into the mattress.

1st Layer – Ice Fabric Cover

The Idle Gel Plush includes a cooling mattress cover with gel infusions and a thin layer of Cooling Buoyancy Foam quilted on top. The foam has a 500 grams per square meter rating, meaning that it is dense, heavy, and absorbent, while the cooling gel infusions compensate for the absence of airflow.

Idle Gel Plush is an excellent choice for people who sweat a lot while sleeping

In other words, the Idle Gel Plush is an excellent choice for people who sweat a lot while sleeping. In addition, the Idle Gel Plush mattress cover is machine washable, which is an added bonus!

2nd Layer: Natural Fire Resistant Barrier

The Idle Gel Plush uses a one hundred percent natural cotton fire-resistant barrier that is devoid of carcinogenic chemicals, fumes, and pollutants instead of a chemical fire retardant.

3rd Layer: 2″ Cooling Buoyancy Foam

This comfort foam is packed with cooling gel and was custom-created for Idle. It’s more sensitive than memory foam, but it still relieves pressure.

4th Layer: 3″ Idle Memory Foam

According to Idle, their memory foam has high thermal neutrality, which means it is less sensitive to temperature changes. As a result, it’s more sensitive and less prone to heat retention than most mattresses.

5th Layer: 8″ Idle High-Density Foam Base

A base layer of foam anchors the mattress, which helps keep it stable and improves its overall longevity.

Idle Gel Plush Mattress Firmness

6 firmness

A woman hugging her bedThe medium firmness level of the Idle Gel Plush mattress is roughly a 6 out of 10 on our firmness scale. However,  Idle rates this mattress at 4.5 to 5.5 out of 10 , which means that the Idle Gel Plush mattress will feel slightly softer or stiffer depending on the body type of the person who is using it.

Those who have a light or average body type should be satisfied with this mattress. They may find their entire body sinking deep enough through the foam layers to receive more than enough pressure alleviation but not enough to feel uncomfortable.

On the other hand, those with heavy body types – specifically those over 240 pounds – are at risk of too much sinkage, which can throw their spine out of alignment or cause them to hit the firmer base foam layer.

With regard to sleeping positions, the medium firmness of the Idle Gel Plush provides a balance of softness and support that suits back and side sleepers. If you are a stomach sleeper, you should probably opt for a firmer mattress instead.

Temperature Control

Chances are, you’ve heard that memory foam tends to retain quite a bit of heat. Indeed, all-foam mattresses, particularly ones containing memory foam layers, tend to be much warmer than innerspring mattresses. Luckily, with a couple of cooling elements,  Idle was able to solve the heat-trapping quickly and effectively !

The first cooling element is a mattress cover made of Ice Fabric. The Ice Fabric is filled with gel, which helps to maintain a neutral temperature and keep the surface of the mattress cool by absorbing heat. The second cooling element is the gel-infused Cooling Buoyancy Foam, which is sewn into the mattress cover and the top of the mattress.

In short, this mattress will offset memory foam’s ability to trap body heat, but it will not keep you cool. So, we suggest it to people who sweat at night on occasion but not to people who have a persistent problem with staying cool while sleeping.

Sleeping Support

In our opinion, the Idle Gel Plush does a decent job of supporting you, even if you end up lying close to the edges of the mattress. When it comes to weight, the  Idle Gel Plush mattress is best for light and average body types . Here are a few things related to your sleeping position that you need to consider before making a purchase!

Back Sleepers

Back SleepersBack sleepers need adequate support to keep their bodies in a proper position, as well as a small amount of cushioning for their joints. That is where the Idle Gel Plush mattress comes in! The top layers will cushion light and average-weight back sleepers, providing them with high-quality sleep.


Side Sleepers

Side SleepersAbove all, the greatest mattresses for side sleepers must provide superior pressure alleviation. This is due to the fact that their pressure points, namely shoulders and hips, sink into the mattress the fastest. Luckily, the Idle Gel Plush mattress has a five-inch foam layer on top of it, which will provide the above-mentioned body parts with superior pressure alleviation.

Stomach Sleepers

Stomach SleepersA firmer mattress is preferable for stomach sleepers. The softness of the Idle Gel Plush is unlikely to keep stomach sleepers’ hips up on top of the foam, no matter their weight, putting them at risk for back pain.

How Much Does the IDLE Plush Mattress Cost?

As of today, IDLE Sleep is giving a special discount of 50%! To benefit from it, just use code TED50 at checkout and get these lower prices:

SizeRegular PriceDiscounted Price
Twin XL:$849$425
Cal King:$1,499$750

While there are some extra cooling layers within the Plush, we are not sure it warrants the jump in price as you get to the bigger mattress sizes.

Unless someone is looking for an extremely cooling mattress, the original IDLE might be the better (and more inexpensive) choice.

Idle Plush Mattress Performance

Purchasing a new mattress isn’t something that you do every day, so knowing what you are getting will help you feel confident while making a purchase.

Motion Transfer

When looking for a mattress, couples should consider its motion transfer capabilities. If a mattress is able to provide you with excellent motion isolation, you will be less likely to wake your partner up whenever you shift positions while sleeping.

Edge Support

With regards to edge support, the Idle Plush foam mattress is pretty average.  When sitting on the mattress’s side, you will notice the edges folding . In fact, you’ll probably roll off of it if you end up sleeping too close to the edges.


The Idle Sleep Gel Plush is made of certified foams, which is a huge benefit.  It contains no PBDEs, TDCPPs, ozone-depleting chemicals, lead, or mercury If you are looking for an eco-friendly product that will help you live a healthy life, this bed in a box will be quite difficult to beat!


The Idle Plush is a luxury foam mattress, meaning that it should last  at least 7 to 10 years . The deep memory foam layers are made with high-quality materials, making the mattress incredibly long-lasting.

It’s typical to notice a little bit of odor when opening a new mattress in a box. It is called off-gassing, and it was present when we opened the Idle Plush. It is not that big of a problem, though, as the odor faded after around forty-eight hours.


The Idle Plush may not be the ideal mattress for sex, as it is comprised of slow-moving memory foam. You may have difficulty moving around on top of it.

What Can We Say About This Mattress

View of the IDLE Plush Mattress with the covers on itIf you’re looking for a soft mattress, I think you’ll have to look far to find one that’s as nice as the Idle Sleep Gel Plush mattress.

Most soft mattresses have a problem with retaining heat, which can lead to excessive sweating and disrupted sleep. Idle has solved this problem by including cooling layers inside the foam, which results in soft and pleasant support, as well as helps balance the mattress’s temperature out.

To sum up, the combination of cutting-edge technology and years of experience of Idle Sleep employees has resulted in a mattress that is difficult to beat. The only issue that I encountered while using it was the average edge support. So, if you decide to buy the Idle Sleep Gel Plush mattress, you are very unlikely to end up being disappointed!
