My Idle Gel Mattress Findings

At first glance, this mattress looks and reads like the hundreds of others that you will find online. In fact, once you start searching for a mattress, you will be inundated with mattress ads leaving you thoroughly confused. As your sleep guide, I have already done the homework and slept on all the leading brands and most of the smaller brands to give a fair assessment of how the Idle Gel stack up.

First off, this mattress is an incredible value. Given the financing options and the 18-month trial this would be my first choice for anyone looking for a memory foam mattress. Chances are you are going to like how it feels. It is great for side and back sleeping and firm enough for occasional stomach sleeping. Ideally, you should be sleeping on your side to avoid snoring and get optimal rest.

Idle really hit the nail on the head with using 3 inches of buoyancy foam. It instantly contoured to my body and the transition layer gave me the proper support. This is where other brands can miss the mark. Too little comfort foam will make the mattress to stiff while too much will make it too doughy.

Idle also provides 2 free pillows with the mattress. You can always use new pillows and these are made with shredded foam that is consistently cut. You can take out foam to make the pillow a little thinner by accessing the zipper on the side.

There’s no motion transfer with this mattress as you can see in the video clip below which makes it great for couples.

This mattress incorporates cooling gel foam on the top layer which helps with heat dissipation but more importantly, the foam isn’t very dense so it is a bit more breathable. It doesn’t have a phase change cover like the Idle Plush but adding that would only temporarily provide some cooling. I slept on this mattress for over 2 weeks and during a heatwave and didn’t have any issues sleeping hot. Most of the time I find that people are still sleeping with a down comforter in the summer. I would instead advise a light blanket.

My Idle Sleep Recommendation

The Idle Gel Foam is exactly the kind of foam mattress I would design for maximum comfort. Subtle changes in the density and types of foam used and how it is all put together can make a big difference and Idle has this feel dialed-in perfectly. Most mattress companies say their feel is a medium-firm but that really means nothing without context. This mattress is a true medium feel and that’s a hard feat to achieve.

  1. How does this compare with their plush model? I’m a side sleeper, tend to be a hot sleeper as well and I’m considering this mattress and was impressed with your review.

    I’ve been considering the Eight Sleep Pod Pro, but the price is a big deterrent, and Molecule as well.
