IDLE Foam Mattress: YouTube Video

We like to pair our written posts, whenever possible, with a video, as we think videos do a better job of showcasing things like feel and firmness. In the video below we did a guide that contains the foam and hybrid mattresses from IDLE.

For anyone that wants to do some more digging, we have a lot more detail about this mattress in the text below.

IDLE Sleep Company Policies

The online mattress industry has a pretty standard setup when it comes to shipping and such. Most companies offer free shipping, free returns, a 100-night risk-free trial, and a 10-year warranty.

IDLE Sleep offers a bit more with their 120-night trial period and lifetime warranty. Off the top of my head, there are only a few other brands, including Layla Sleep, Nectar, and DreamCloud that also offer lifetime warranties.

With the trial period, you get four full months to makes sure that it’s as good as you dreamed (#SleepPun) it would be. If you decide it isn’t quite what you’re looking for at any time within that trial period, you can call the company and have the bed picked up, free of charge, and receive a full refund. But if you do keep the bed, you the company will back it with a limited lifetime warranty, which, according to their website, means “in the event of a defect, [IDLE] will repair the defect or replace [the mattress] with a current comparable model and size of a IDLE Sleep mattress.” You can read the full warranty on the IDLE Sleep website.

As for the shipping process, the bed ships in a box. It’s actually compressed, vacuum-sealed, and then rolled up so that IDLE manages to fit the entire bed (even a king size) into a box about the size of a mini fridge. All you need to do is cart the box inside your home, remove the packaging, and allow the bed to fully inflate. Here’s a look at the unboxing process.

After you’ve got the bed all set up on your mattress foundation, you should allow it about 24-48 hours to fully inflate and off-gas (if necessary). Because the bed has been wrapped in plastic for several days, it could take a little while to take its intended shape and purge any clean plastic smells. This is very common for most new mattresses.

IDLE Sleep Mattress Price And Coupon Code

This is not a cheap bed compared to the myriad budget mattresses available online today, but we would consider it a pretty good value. The company uses premium materials and this is actually quite a thick mattress. So, while it’s not cheap, it is an affordable mattress, relatively speaking. You can see the pricing breakdown in the table below.

SizePrice (MSRP)
Twin XL$1,129
King / Cal King$1,799

IDLE Sleep, like most other bed-in-a-box mattress brands, plays the coupon game. They set prices a bit high and during major holidays tend to offer deeper discounts. In fact there should be a coupon on this page to save you money on this bed or you can check for current deals and offers.

Your Height And Weight Are Important

How much you weigh makes a big difference in how a mattress feels. This is a point that often goes overlooked. In our guides, we write through the eyes (or body) of an average sized person (call it 150 to 225 pounds). However, lighter people (150 pounds or less) will find that mattresses generally feel firmer to them. This is because they barely place any pressure on a mattress. As such, they sleep more on top the bed and never really sink in.

On the opposite side of the spectrum, heavier folks will generally find that beds feel softer. This is because (you probably guessed it) they exert a lot of extra stress and pressure and so sink in quite a bit more. Although, in some cases, more weight means you’ll sink right through the comfort layers and be left sleeping on the support layers, which is its own uncomfortable problem. Keep this point in mind as you peruse through this post.

Construction Of The IDLE Foam Mattress

IDLE makes all their mattresses two-sided so that they can be flipped over. This means their construction is sort of like a sandwich. Or a palindrome.

The All-Foam has five layers, plus the cover. The first layer is 1″ of IDLE Quilting Foam (for softness and added comfort), then 3″ of Gel Swirl Buoyancy Foam (for responsiveness, support, and pressure relief), and then a 6″ High Density Foam core (for some serious support). Layers 4 and 5 are the same as layers 2 and 1, respectively. Palindrome, remember?

The fact that this mattress is flippable makes it unique from a lot of other mattresses out there. In fact, there are only a handful of other double-sided mattresses on the market—some of those include Zenhaven and Nolah Signature 12″.

Overall Feel And Firmness

IDLE’s All-Foam bed feels somewhere in between a memory foam mattress and a neutral/soft foam mattress. It has a bit of that sink-in feeling you expect from memory foam, but not overwhelmingly so and it isn’t as dense as a typical memory foam mattress. We think it sort of feels like Casper Wave or a thicker Leesa mattress.


It’s also important to note that IDLE makes this mattress in two feels: Medium and Luxury Firm. The Medium option is the most popular of the two and would put it at a medium on our firmness scale (shocking). Keep in mind, though, that your weight will determine how soft or firm a bed feels to you.

Support And Responsiveness

IDLE’s All-Foam bed provides ample support with minimal sinkage. That makes it a good option for heavier people if you absolutely have to have an all-foam bed. In general, however, recommend that heavy folks look into spring and hybrid mattresses.

The responsiveness with all-foam beds is typically fine, if not super impressive. They don’t bounce back immediately since they don’t have any coils. The IDLE All-Foam is no exception. It isn’t slow to bounce back, it’s just not immediate. You won’t have any trouble turning over, though, and you won’t feel like you’re “stuck in the mud” either.

Back And Stomach Sleepers

We think back and stomach sleepers are going to sleep well on this mattress. It has the support you need around your hips and trunk, but it’s still a soft, comfy bed.

It’s crucial for back and stomach sleepers to keep their spine properly aligned throughout the night. A lot of times with mattresses that fail in this regard, back and stomach sleepers will notice a lack of support beneath their lower back because their hips are sinking too far into the mattress. This may lead to some lower back pain the morning. Lucky for you (if you’re this type of sleeper), this mattress provides good support underneath your entire body.

Side And Combo Sleepers

This bed is going to be a good one for side and combo sleepers, as well. Because it’s in the middle of the firmness scale and offers both support and pressure relief, it’s an all-around accommodating mattress.

When you’re on your side, the mattress is very soft and provides a good amount of pressure relief for your hips and shoulders. We don’t envision any side sleepers waking up with hip pain or experiencing any discomfort around their shoulders.

More About IDLE’s Cover

The cover on this mattress is nice and soft, and is stitched into the top layer of foam so it isn’t going to bunch up under your sheets.

Close up on IDLE’s cover

It’s made with a Thermocool fabric, which is supposed to work with your natural body temperature to keep you comfortable. We didn’t notice that it was an especially cool mattress, though. We don’t think it’ll make you overheat or anything, it just isn’t going to actively work to cool you down. We’d say it’s just going to be temperature neutral, which is a category most bed-in-a-box all-foam mattresses fall into.

However, for those on the heavier side, it may sleep a tiny bit warmer since these sleepers will sink in more and the mattress will sort of hug you.

Edge Support And Motion Transfer With IDLE Beds

These two factors are especially important for couples, so listen up if that’s you. When it comes to edge support, we’d say this bed is pretty good, particularly for a bed that’s made entirely of foam.

Solid edge support

The edges do give a little bit as you migrate towards the perimeter, but it’s still not bad by any means. It’s just not the best edge support we’ve ever seen, but at the end of the day it’s not going to be an issue. Feel free to go ahead and utilize that outer two inches of the bed.

Another characteristic that we’ve come to expect from all-foam beds is really good motion transfer control. And IDLE’s All-Foam is no exception. It performed well in our test. Absolutely no problem whatsoever.

You can roll around and turn over all you want without any problematic cross-bed motion. You could perform the climactic scene from any of the Bring It On movies over there and not wake up your partner. But don’t do the one from Bring It On: Worldwide. That movie sucks even more than the other sequels.

Final Thoughts With IDLE

Yes, this bed is on the expensive side for an all-foam mattress, but it does offer a lot more than the typical bed in a box. It’s thick, durable, and accommodates a variety of sleeper types. Bottom line is if you’re looking for a neutral all-foam mattress that has the potential to last you a long, long time, this IDLE mattress is a great choice.
