The Idle Sleep mattress is a hybrid mattress that is 2-sided. That means you can sleep on either side and flip it to make it last longer. This is the first 2-sided hybrid mattress I have reviewed and so far I am very impressed with it. The biggest reason for people switching to a new mattress is that it no longer offers the support they need. This is caused by sleeping on it for a long period of time and creating impressions.
You can choose from two different firmness levels with the Idle sleep which are “medium” and “luxury firm”
Overview of the Idle Sleep Hybrid Mattress
Below is a video overview of the mattress. I am on the medium-firm version here.
A queen-size Idle Hybrid retails for $1,499 but you can get $300 off right now with their coupon code SHERPA25OFF at checkout. Idle also offers a financing option through Klarna. Delivery times are between 3-10 business days. Shipping is free and the mattress comes with a lifetime warranty and 120-night sleep trial so you can try it out in the comfort of your home for up to 120 days and return it for free within that time if you don’t like it. Idle Sleep asks you to try the mattress out for at least 30 nights before returning. That’s to give it a fair chance it takes a little while for your body to adjust to a new mattress so it’s hard to make any judgments about it right away.
Regarding the lifetime warranty, this is a 20-year warranty and after 20 years, Idle will let you buy a new mattress at 50% off. Although 20 years is a long ways away!

How Much Does the Idle Sleep Mattress Cost?
Below is the current pricing before the exclusive Sleep Sherpa discount.
My Idle Sleep Findings
Idle Sleep was created by a sleep industry veteran with over 18 years in the mattress industry. This is somewhat uncommon in the online mattress world where most of the company leadership is more experienced in marketing rather than mattresses themselves.
The Idle Sleep Hybrid comes in a box like this. It is a heavy mattress weighing 142 lbs. for a queen size. This is a very good indicator of quality especially since there is a spring system occupying the middle. I expect this mattress to have a long life just given the construction.
The mattress is easy to unbox and once you cut open the plastic it pops into shape quickly. I would give it at least 7-8 hours before it is fully expanded. Here’s a picture of the mattress right out of the box before I cut open the plastic to allow it to expand.
Here’s a picture of the mattress just after opening it. As you can see it is just about full size. That’s because the springs pop open instantly.
I set up this mattress on a bed with slats. It will work on a box spring or even the floor. As long as you have a flat, solid surface, you’re good.
So how does the Idles Sleep Mattress feel? To give you an idea, here’s a picture of the sinkage on the medium-firm version.
As you can see you get good sinkage right off the bat. This is true with the luxury firm version as well but to a lesser extent. When you sit on this mattress you really sink into it and it cradles you more than the luxury firm.
I would say the medium-firm version is around an 8.5 out of ten on the firmness scale with 10 being the softest. The Luxury firm is considerably firmer and is about a 6 out of 10. Of course, weight all plays a role in this, and the heavier you are the softer these mattresses will feel. I weight about 195 lbs.
Here’s how the mattresses perform with motion transfer. First the medium-firm Idle:
The mattresses have pocked coil systems which isolate motion so for being a hybrid mattress this does a great job with motion transfer. I would say if motion transfer is a primary concern, the luxury firm would be the better choice.
Below are some videos that show how cool the mattresses sleep. I used my infrared camera to show heat dissipation off the surface of the mattress. Overall this mattress is about middle of the road for a hybrid mattress and sleeping cool. I don’t think it sleeps hot and nor does it sleep especially cool. So if sleeping hot isn’t an issue for you this mattress is great.
The Idle Sleep mattress uses the quantum coil system. There are firmer coils along the perimeter of the mattress which makes for better edge support. This allows you to maximize your entire sleep surface and sleep right up to the edge without feeling like you will fall off.
My Idle Sleep Recommendation
Overall I was really impressed with both versions of this mattress. I prefer a softer feel and the medium firm was just the right amount of softness and support for me. People who complain about sore shoulders at night will appreciate how much this mattress sinks and contours. People who want to go the firmer route should go with the luxury firm. I would also recommend the luxury firm to heavier sleepers as the medium-firm probably won’t give them the necessary support.
I am very impressed that this is a two-sided mattress. If you flip this mattress on a regular basis you should be able to extend the lifespan of the mattress over what you would normally get out of a one-sided mattress. Since this mattress comes with stitched handles, flipping is easy and can be done by one person.
If you’re looking for a quality hybrid mattress that should last beyond 8 years, I would take a serious look at Idle Sleep. It is very competitively priced for the quality of materials and construction.
