Latex Mattress Help

Hi HoustonPerson,

First some of the basics that I link for anyone that is experiencing “symptoms” on their mattress so we are on the same page …

There are no “standard” definitions or consensus of opinions for firmness ratings and different manufacturers can rate their mattresses very differently than others so a mattress that one manufacturer rates as being a specific firmness could be rated very differently by another manufacturer. Different people can also have very different perceptions of firmness and softness compared to others as well and a mattress that feels firm for one person can feel like “medium” for someone else or even “soft” for someone else (or vice versa) depending on their body type, sleeping style, physiology, their frame of reference based on what they are used to, and their individual sensitivity and perceptions. There are also different types of firmness and softness that different people may be sensitive to that can affect how they “rate” a mattress as well (see post #15 here) so different people can also have very different opinions on how two mattresses compare in terms of firmness and some people may rate one mattress as being firmer than another and someone else may rate them the other way around. This is all relative and very subjective and is as much an art as a science.

“Support” is often misunderstood because the goal of a “supportive” mattress is to keep the spine and joints in good alignment and this requires the type of contouring support that allows some parts of the body to sink in more (softer) and some parts of the body to sink in less (firmer) and this will vary on an individual basis and the overall firmness of a mattress isn’t necessarily an indication of how well it will keep your spine and joints in good alignment because it depends on which layers are softer and which layers are firmer. A mattress that is too firm won’t support the more recessed parts of your body (such as the waist or small of the back/lumbar) and a mattress that is too soft won’t support the heavier parts of your body (such as the hips/pelvis).

There are some suggestions in post #4 here that may be helpful for a mattress that is too soft or is sagging but it’s very possible that this could be related to the support system under the mattress (your bedframe and foundation). An all latex mattress will generally do best with a firm, flat, and evenly supportive support surface underneath it that has minimal to no flex under the mattress and for larger sizes with at least one center support beam that has good support to the floor to prevent any sagging in the middle of the mattress. The components need to be strong and durable enough to support the weight of the mattress and the people sleeping on it without some of the parts bending, sagging, or breaking over time. The support surface under the mattress should have enough surface area to prevent the mattress from sagging through any gaps or spaces in the support surface over time but still allow some airflow under the mattress. I would suggest that in a slatted support system that any gaps between the slats are no more than 3" (with 1 x 3 slats) although less than that would be better yet.

You could confirm whether this is an issue by putting your mattress on the floor for a few nights to see if it makes any difference.

Just for reference … returned or exchanged layers or mattresses aren’t resold or reused as new (at least it would be against the law to do so and a reputable manufacturer wouldn’t take the risk of doing so).

While I can’t know for certain … based on your description (and assuming that your support system is suitable for you and the mattress and isn’t the cause of the problem) … the most common cause for lower back pain is a mattress that is too soft and either has comfort layers that are too thick/soft or a support core that is too soft and I would guess that this is what may be happening.

Your mattress is a component mattress which has the advantage of having layers inside it that can be rearranged (or exchanged) to change the level of support or the level of “comfort” and pressure relief.

It would be helpful (if you know) if you could let me know the firmness of each of the three layers in your mattress and the current order of the layers that you are using (I believe the “default” is a softer 2" layer on the bottom, a firmer 3" layer in the middle, and a softer 2" layer on top). If you aren’t sure you can call Astrabeds and ask them about the firmness of the layers in your order. You may also be able to check the relative firmness of each of the layers yourself based on “feel”.

Assuming that both of the 2" layers are the same and are softer (which may or may not be the case) … the first thing I would try is to remove the bottom 2" layer and sleep on the remaining two layers for a few days (the 3" firmer layer on the bottom and the 2" softer layer on the top) and see how it affects your sleeping experience. The two layers will be loose inside the cover but for now the goal is to see how the firmer configuration changes your experience and your back pain when you sleep on your back.
