Soft (20 ILD) mattress topper still too hard for me and still slept hot (althoug

Hi Clock24.

Welcome to our Forum :slight_smile:

I see why you feel discouraged in your attempts to fix your current mattress. People with an hourglass body shape typically have a hard time finding the perfect balance between pressure relief and neutral spinal alignment for all sleeping positions. To adapt a Jessica Rabbit’s saying “I’m not bad, I’m just drawn that way” …. not too bad, just need a solution :slight_smile:

You seem to have a good understanding of how your body shape affects your sleeping landscape. I don’t know how much you read since finding our site about the two main functions of every mattress

  1. to keep your spine and joints inside the range of their neutral alignment in all your sleeping positions and
  2. to relieve pressure by redistributing your weight across the surface of the mattress.
    In your case getting a good match for your side sleeping position means that you may have trouble when you change positions during the course of the night. Some people with similar issues look into training themselves to sleep primarily on their back and others make sure that they focus on getting it right for their primary sleeping position and opt for zoned mattresses.

Glad to hear that the Sleep on Latex topper helped with the pressure points too bad it still needs fine-tuning. I’d give some time to your body to unlearn the old ways and relearn and adapt to the new sleeping environment. A “very curvy” profile calls for either zoning or thicker mattress, however adding another topper on the existing one may not solve the issues you are having. Thickness and softness are very related and work together, adding more thickness to an existing 14.5" mattress/topper combo may compromise needed support for maintaining neutral alignment. Assuming that you’ve read the tutorial post here before deciding your next step I’d start by looking at the relationship between alignment and pressure relief issues and later at the temperature microclimate that you are trying to address. (Note also that memory foam comfort layers change softness/firmness with temperature variations.)

There is more about primary or “deep” support and secondary or “surface” support and their relationship to firmness and pressure relief and the “roles” of different layers in a mattress in In post #2 about firmness and support and in post #4 here may be helpful in clarifying the difference between mattress “support” and “pressure relief” and “feel” and it can also provide some useful insights into the reasons for pain and/or discomfort on a mattress.

Because your shape is much more curvy than flat, some parts of the body (hips/pelvis) weigh more than others and some parts (shoulders) are wider than others… good support/alignment means that parts of your body need to be “allowed” to sink in more deeply and that other parts of your body need to be “stopped” from sinking in too deeply so that the end result is neutral alignment of the spine and joints. To help with understanding this I always link Post #6 about sleeping posture and alignment which uses an example of floating in the air and slowly sinking onto the mattress surface to help you visualize this.

ILD is used to describe foams and gels, and not horsehair toppers. In case of foams, anything with an ILD of 12 or under is going to be considered “very soft.” From what you describe you need something that is both soft and breathable/moisture wicking. Lyocell (wood pulp), bamboo, linen, silk, wool, horsehair is all good moisture-wicking materials for bedding and will vary in perceived “softness.” . One caveat, horsehair as a topper will tend to compress a bit over time and is a bit of a firmer topper material. Wool is particularly know for its’ heat and moisture-wicking properties so it may not be a bad idea to try a wool product. You may wish to read through this post about how to chose a topper.

As far as the sleeping microclimate goes, even though Latex, in general, is the most breathable and “temperature neutral” of all the different types of foam materials I’d keep in mind that the firmness of a mattress and how much you sink into it can also affect sleeping temperature as well. I agree that you also have to consider other variables that are involved in (including your room temperature and humidity, your sheets and bedding and bedclothes, your mattress protector or any mattress pads you are using, and where you are in the “oven to iceberg” range) and there is more about tracking mattress temperature regulation issues potential causes ~ Post #2 here (at least to the degree possible for a specific mattress) and the posts it links to that may be helpful.

For moisture-wicking pajamas, here are some that aren’t made of synthetic or athletic materials:

Dreamsacks: Bamboo
Fisher’s Finery: Bamboo, Organic Cotton, Spandex
