In the past, the majority of mattresses were flippable, allowing people to turn them over every few months and prevent sagging and premature indentations. In more modern times this design is becoming increasingly rare; many of the best bed-in-a-box mattresses are designed with support layers, transition layers, and comfort layers and should not be turned over.

This is what makes the Idle Sleep Hybrid stand out in the crowded online mattress market. It is a flippable hybrid mattress that comes in either Medium or Luxury Firm. What’s more, Idle Sleep offers a model that has one Medium side and one Luxury Firm, giving sleepers two firmnesses in one mattress!

To find out if this is a mattress to flip for, read on for my unbiased Idle Sleep Hybrid mattress review.

Idle Sleep Hybrid Mattress Firmness And Feel

It’s essential to consider a bed’s firmness and feel when shopping for a new mattress. These factors have a big impact on whether a mattress will feel comfortable for different types of sleepers.

How Firm Is The Idle Sleep Hybrid?

All versions of the Idle Sleep Hybrid are flippable, but customers have three options – they can opt for the model where both sides are Luxury Firm, one where both sides are Medium, and a model with one Luxury Firm side and one Medium side. The Luxury Firm/Medium blended model gives customers two firmness options in one mattress.

We tested the Medium model of the Idle Sleep Hybrid mattress. In terms of firmness, the Idle Sleep Hybrid Medium feels like a 7/10, a bit firmer-than-average. The top layers are quite soft, and it is very easy to press my hand in. Then I hit the more firm transition and support layers and my hand stops.

Sleeping On The Idle Sleep Hybrid Mattress

This firmer-than-average mattress is a fantastic match for back sleeping – my hips sink in just the right amount and the pocketed coils offer excellent support. I am also getting a bit of contouring from the foam layers on top.

Side sleeping, the Idle Sleep is giving me a decent amount of pressure relief and I don’t feel an extreme amount of pressure on my shoulders and hips. That being said, those who sleep just on their sides may want to look for a softer, more pressure-relieving mattress.

Finally, when I move to my stomach, the Idle Sleep is firm enough and gives me all of the support I need. I don’t feel my hips bowing into the mattress, and I feel like I am in proper neutral spinal alignment.

What Does The Idle Sleep Hybrid Feel Like?

With its hybrid construction, the Idle Sleep has a balanced feel. The top has some of that memory foam feel, but it is also quite responsive. Combine that with the pocketed coils, and the Idle Sleep Hybrid has a great balance of comfort and support.

IDLE Sleep Hybrid Mattress - Back Sleeping

Average Weight Sleepers – 130 lbs – 230 lbs

Most average weight sleepers should really enjoy back sleeping on the Idle Sleep Hybrid mattress as it should allow their hips to sink and the foam to contour. Additionally, the Idle Hybrid is a great option for average weight stomach sleepers – it’s firm enough to give lots of support and spinal alignment. Moving to the side, the Idle Sleep Hybrid should give a decent amount of pressure relief, however, average weight side sleepers looking for a mattress with more pressure relief may want to look elsewhere.

Heavyweight Sleepers – Over 230 lbs

The Idle Sleep Hybrid mattress may feel more firm (around a 7.5/10) to heavyweight sleepers who will sink deeper through the top comfort layer.

Heavyweight back sleepers should get just the right amount of support from the Idle Sleep Hybrid as their hips should sink and the mattress should conform to their body. Heavyweight stomach sleepers should feel even support across the entire body when sleeping on the Idle Sleep Hybrid. However, those who are much larger, in the 300 to 500 lb weight range, might need a more firm mattress.

For heavyweight side sleepers, the Idle Sleep Hybrid may be too firm and they should check out our list of best mattresses for heavyweight sleepers.

Lightweight Sleepers – Under 130 lbs

Lightweight sleepers may not be as comfortable on the Idle Sleep Hybrid mattress. Lightweight back and side sleepers might find that the Idle Sleep Hybrid mattress feels too firm because they won’t be heavy enough to sink into the mattress and enjoy the pressure relief. However, the Idle Sleep Hybrid mattress should provide decent support for lightweight stomach sleepers.

Idle Sleep Hybrid Mattress Construction

Now that you know what it feels like to sleep on the Idle Sleep Hybrid mattress, let’s talk about the construction and what materials make up the mattress.

IDLE Sleep Hybrid Mattress Review


The soft cover is quilted with 1” of contouring foam. It also contains Thermocool fabric to help with temperature regulation.

Comfort Layers

For comfort, there is 2” of Idle Cooling Buoyancy Foam. Underneath, you will find a 1’’ foam transition layer.

Support Layer

The center of the mattress provides the most support. With 6” of pocketed coils, you should feel very secure when sleeping on the Idle Sleep Hybrid.

Since the Idle Sleep Hybrid mattress is flippable, the bottom of the Medium model will be identical to the top. There is a 1” foam transition layer followed by 2” of Idle Cooling Buoyancy Foam and the Thermocool cover quilted with contouring foam.

Mattress Height

The Idle Sleep Hybrid mattress is 14” tall. This is a taller-than-average mattress so be sure you check that the sheets you use will fit the bed–you may need to look for deep-pocketed sheets.

Idle Sleep Hybrid Mattress Performance

Mattress performance is a huge factor in your purchase decision. Let’s see how the Idle Sleep Hybrid did when put to the test.

Sleeping Hot Or Cold

The Idle Sleep Hybrid should sleep quite cool because of the coils and Buoyancy Foam. The coils will promote airflow through the mattress, and the Idle Buoyancy Foam is more breathable than memory foam and should not trap too much heat.

Motion Transfer

To test out the motion transfer on the Idle Sleep Hybrid, I first placed a glass of water in the center of the mattress. I then pressed into the mattress all around the glass, and it was disturbed quite a bit. Also, I lay down on one side of the Idle Sleep Hybrid while Marten moved around on the other side and got in and out of bed. I did feel his movements transfer to my side of the bed. Those who need a mattress for couples should just keep these results in mind.

Edge Support

Sitting near the edge of the Idle Sleep Hybrid mattress, the foam on top collapses quite a bit, and I don’t feel extremely secure. When I lie down near the edge of the mattress, the edge collapses a bit, and I feel somewhat like I might roll off. Edge support really isn’t a highlight of the Idle Sleep Hybrid mattress.

The Idle Sleep Hybrid is very durable. The mattress is flippable, which seriously adds to the longevity of the mattress.

How Does The Idle Sleep Hybrid Compare To Other Mattresses?

If you are considering the Idle Sleep Hybrid mattress, you’ve probably looked into other unique bed-in-a-box mattresses. So let’s review how the Idle stacks up against the Purple mattress.

Compare Idle Sleep Hybrid to other mattresses on our mattress comparison page.

Idle Sleep Hybrid Vs Purple Mattress Comparison

First off, the Idle Sleep Hybrid mattress and the Purple mattress are different in terms of construction. The Idle Sleep Hybrid is thicker than the Purple, and it contains a combination of foam and coils. However, the Purple is famous for its hyper-elastic gel polymer and it really is unlike any other mattress material – firm and pressure-relieving at the same time.

The Idle Sleep Hybrid’s construction makes it a firmer mattress than the Purple – the Idle feels like a 7/10 in firmness while the Purple feels like a 6.5/10. Being a firmer mattress, the Idle Sleep Hybrid is probably a better fit for back sleepers and stomach sleepers. Also, given that it is thicker and more supportive, the Idle Sleep Hybrid should work for heavier sleepers.

The Purple mattress should be a better choice for side sleepers because it offers better pressure relief under the shoulders. It is also a good fit for those who simply like a softer mattress.

These two mattresses vary in terms of price. The Idle Sleep Hybrid is about $200 more expensive than the Purple mattress. It’s important to remember that you are paying for a long term investment when purchasing the Idle Sleep Hybrid since it is reversible.

Who Should Get The Idle Sleep Hybrid?

  • Those who are looking for a good value mattress that’s flippable and a long-term investment.
  • Back and stomach sleepers looking for support.
  • People who enjoy a firmer-than-average

Who Should Get The Purple?

  • Average and heavyweight side sleepers who will activate the Purple’s gel grid to enjoy some body contouring.
  • Hot sleepers who are looking for a mattress that sleeps cool.
  • Those who want one of the most unique feeling mattresses.
