Best Mattress for Side Sleepers? Idle Sleep Gel Plush Mattress

Idle gel memory foam mattress

Of all the sleeping positions, side sleepers are most likely to need a very soft mattress. Side sleepers tend to have more pronounced pressure points at the hips and shoulders and so you need more cushioning at those points. The truth is, most side sleepers benefit from a soft mattress that gives and lets your spine align straighter.

So, the last thing a side sleeper needs is a firm mattress. If you’re searching for a new mattress, keep reading to see if this is the best mattress for you. We may earn a commission when you shop through our links.

Are you a side sleeper who is searching for a new mattress? This is the best mattress for side sleepers who love memory foam. Then the firmness is very important – probably the most important factor when looking at mattresses.

That’s because the #1 one reason people return a mattress they buy online is because it’s TOO FIRM.

What Side Sleepers Need Most

When you’re a side sleeper all of your body weight is more concentrated on a few pressure points (your shoulders and hips). So choosing a mattress that has cushioning is especially important for you. Otherwise you can end up with shoulder and hip pain every morning.

In general, unless you’re on the heavier end (or over 230 lbs), you should choose a medium to soft mattress to help prevent that pain. Or just for better sleep. The good news is Idle has a medium option too. We just wouldn’t recommend a firm.

Your weight also matters. Someone who is heavier will sink into a mattress (especially a soft one) more than someone who’s lighter. But the good news is you won’t hit the firmer bottom layers of the mattress because it’s thicker than what we typically see (14 inches on the plush and 12 inches on the medium).

Now let’s look a little deeper and show you the layers of the Idle plush gel memory foam mattress.

Idle Gel Plush Mattress Unboxing

No matter how many unboxings we do, we always find them fun and fascinating. Want to see what the Idle Gel Plush looks like out of the box? Watch our video of the gel plush mattress being unboxed here:

Mattress Cover

Features a quilted surface that has the gel sewn right into it. The cover is pure cotton and yet has a silky feel. So it’s super soft and luxurious. The cover unzips and is washable.

However, I always recommend that you get a mattress protector because it’s not going to be easy to wash this cover and it’s not waterproof. Idle has a 5-sided waterproof mattress protector. It’s made of tencel fabric and covers all 4 sides plus the top of the bed. Most mattress protectors just protect the top layer, not the sides. So the next time you spill a cup of coffee and it goes over the sides of the bed, you won’t have to worry – you’re covered!

A mattress protector is like buying a case to protect your phone. It prolongs the life of your mattress. Once something like liquid or food gets into the foam you’re not getting it out and it’s going to start breaking down the foam and get bacteria inside your bed. So be sure to grab a protector if you don’t already have one.

Idle Gel Plush Mattress Layers

First Layer

1″ top layer of foam that reacts faster than memory foam to help cushion your pressure points.

Base Layer

3. 3″ of Gel Infused foam that they call Buoyancy Foam. To add extra durability to our mattresses Idle uses a 2.4lb base compared the industry standard of 1.8lb. The gel adds coolness to the bed.

Overall, there was some smell from this mattress but it did lessen quickly. It came out of the box ready to sleep on almost right away (you could sleep on it that same night that you open it). However, the pillows did need some time to fully expand.

2 FREE Pillows with Mattress Purchase

When you order an Idle Plush mattress there are two pillows included in the box. They are totally flat when you open the packaging, but they become plumper with time (you can knead them to make the process faster). The pillow cover comes off and will unzip to show another chamber that holds the shredded memory foam.

You can take out foam and adjust how much fill is inside to get the exact feel you want. No one will tell if you prefer a flat pillow (although side sleepers usually opt for more support).

We got a queen and it comes with 2 FREE pillows.


Idle Mattress Cover

Firmness Of The Idle Plush Memory Foam Bed

This luxury memory foam mattress offers a superior 14″ thickness. Not only does this give you a premium feel, but also a more cushioned and soft all foam bed. This mattress will come in right around a 4.5 to 5 on a firmness scale. Giving you a more medium to medium-soft feel. But we think it’s actually softer – more like a 3.5.

Motion Isolation

All foam beds usually have very minimal motion transfer anyway. So if you’re sleeping. The fact that this mattress is also a little softer means you have even less motion transfer. So if you sleep with someone else or even a pet, you won’t feel the mattress move as much when they do.

Edge Support

How supportive are the edges of the mattress? Can you sit on the edge or sleep on the edge and not feel like you’ll roll off? The edge support also affects how easy it is to get in and out of bed. Since this is a softer mattress, it’s going to sink down on the edges. So edge support is ok, but if that’s a concern you have, can look at one of Idle’s hybrid models or their other foam mattress.


The Idle Plush mattress is a great price especially when you consider how thick it is at 14″ – an additional 4 inches than most foam mattresses sold online.

Currently the most popular size, queen, the Idle gel memory foam queen mattress is only $1561 before coupon. It does come with 2 FREE pillows, free shipping and an 18 month trial period. So you have a year and a half to try it out in your home and if you want to return it you can get a full refund. To top it off you also have a lifetime warranty.

Best for Side Sleepers – Final Evaluation

The plush Idle Sleep mattress has a lot to love with an 18 month sleep trial and lifetime warranty. This comes with every Idle Sleep mattress. So they really stand behind their product.

And again, if you like what I call marshmallow beds that you just sink into and that are snuggly and comfortable, then you’ll love this mattress. It’s definitely more plush than the other mattresses on the market that are mostly medium.

We don’t usually talk about other mattresses in a mattress review – it’s usually specific to that mattress only. But Idle Sleep doesn’t have just one model – you can choose from their hybrid model if you want a medium or medium firm spring mattress.

Idle’s other gel foam mattress has a medium feel and is 12” thick. Just remember that their mattresses are 14 inches thick EXCEPT this one. Yet it’s still thicker than most.

And last of all they have hybrid models – with foam and springs. The Idle Hybrid mattress is their best seller. But it comes in medium and medium firm or luxury firm. You can get one side of the bed one firmness (medium to firm) and the other side another firmness. Plus they’re flippable so you can get more wear from each side.

So no matter what your preference, Idle pretty much Idle has you covered as the one of the best mattress for side sleepers. The coupon for 20% off is good on any mattress on their website.
