Putting the layers together - overview

[Sensei]

Hey gme109,

Good to see you back here on the TMU Forum . Thanks for your question.

Is there any inherent disadvantage to putting a softer latex layer under a firmer latex layer? I recently purchased an all natural latex mattress which consists of three layers. The bottom layer is 6" of firm latex followed by a 2" medium latex layer then a 2" soft latex layer on top. At first it felt perfect, providing good support and comfort, but after the first 2 months I started to experience some back pain as the top layer became a little too soft. I then swapped the top softer layer to the middle and the medium firmness to the top, which solved the low back pain problem, and still provided comfort. Just wondering if that’s a no no?

The comfort layers in a mattress are arranged for the best way of supporting a user’s weight, which is an estimate based on the manufacturer’s experience with their customers. Generally speaking, the softer layer goes on top of the firmer, but there is nothing wrong with putting the softer layer underneath a firmer one to give you the preferred comfort you are seeking.

I also have the option of trading my softer top layer in for a medium firmness at no charge to me, but I have a feeling that may wind up being too firm overall, creating pressure points.

You could also try removing the soft latex layer completely which would give you an idea of how a “medium firmness” may feel before making an exchange. IMO, if you feel that your current setup is providing the correct support and comfort for your PPP/ Pressure relief, Posture and alignment, and Personal preferences, it is perfectly fine to keep things as they are. This configuration should cause no harm to the mattress’s other components.

Would be interested to hear more comments later on your experiment after a sleep trial period…

Thanks,
Sensei
