Hi marioana.
Welcome to our
Mattress Forum!
I need some help deciding between 2 mattresses, the Avocado Green and the Sleep on Latex medium.
Even though the final decision is not always easy to make the good news is that you are looking at two mattresses with no lower quality materials or “weak links” in their design and usually if there are no clear winners between them it is usually a good indicator that you’ve done some very good research. Both your finalists have a 100-night sleep trial with free shipping and returns so you have options if something is not to your liking.
The Avocado Green Mattress uses 100% NR Dunlop Latex and a 3 zone pocketed innerspring and has been mentioned a few times previously here on the forum. Sleep on Latex is one of the

and you can also search our forum and read the many posts and comments about them.
First some info about us. I am a 5'0'', 115 lb stomach sleeper and my husband is 6'3'', 230 lb side sleeper and occasional back sleeper.
For your stomach sleeping position, you may wish to review the guidelines in this
Sleep Positions Article
[url] so that you avoid hyperextension in a swayback position that can cause back issues. Both the AG and the 9” Pure Green mattress medium version could be a good fit for your husband as he is a combo sleeper (spending time primarily on his side and occasionally his back) but because you are a prone sleeper you would need a surface that is firmer and less forgiving. As you noticed, the only possible “customization” for AG, would be adding the softer pillow top but with adding it you may lose the support that you need to keep your spine in proper alignment, on top of adding $500 to the cost. Because Pure Green is a component style system you have many options to get the right softness/firmness for your needs. Additionally with PG, if any fine-tuning is necessary you can also add a topper 1” to 3” depending on your need and preferences and for a better price point.
In terms of specs this is what you are looking at for each of the mattresses you are considering:
AG standard 11’ mattress uses:
2” of 75 kg/m3 / 20-25 ILD, medium Dunlop comfort layer
1” of 85 kg/m3 / 26-31, medium-firm Dunlop (under the innerspring unit).
8” 3 zone Leggett & Platt Quantum Edge Combi-Zone pocketed innerspring unit.
Ag pillow-top 13” version adds 2” of 65kg/m3 / 14-19 ILD, soft Dunlop latex.
Sleep on Latex’s 9” Pure Green mattress medium version uses
2" 20 ILD (of 4 lb/ft3) Dunlop top comfort layer
6" 30 ILD (of 4.9 lb/ft3) Dunlop support layer
And the 9” PG Firm Version
2" 30 ILD Dunlop top comfort layer
6" 44 ILD Dunlop support layer
My husband doesn't like being warm at night and SOL tends to run warm from what CR said. Also is not as good as the Avocado Green for large side sleepers but is better at stabilization and is cheaper (we want a king, and if we choose the pillow top for Avocado Green that makes it about $800 more expensive than SOL)
In very general terms ... the layers and components of a sleeping system that are closer to your skin will have a bigger effect on airflow and temperature regulation than layers and components that are further away from your skin and softer mattresses will tend to be more "insulating" and for some people can sleep warmer than firmer mattresses and how they compare would also depend slightly on the order of the layers and components
Both mattresses you are considering have wool in their covers and wool has excellent characteristics in being temperature neutral. PG has 1” of quilted wool in their cover and AG has a very thin layer of wool (something like 2 oz per square foot.) in their cover so you would feel more the temperature effects of the layer underneath. Wool
has a structure
that has a more porous inner core which can absorb large amounts of moisture without the moisture coming into contact with the skin. This moisture which is held inside the wool fiber itself can then evaporate in a more gradual process which helps to regulate temperature much better. Breathability (airflow) creates a drier microclimate and encourages evaporation as long as the material isn't saturated with moisture against the skin. Wool can be both insulating by trapping air and warming and allow evaporation which is the reason it does such a great job of regulating temperature in both directions. It can also hold moisture in the inner core before the moisture comes into contact with the body while other fibers become soaked right through the fiber.
Both mattresses you are considering have Latex as the uppermost layer (closest to your skin) Latex, in general, is also the most breathable and "temperature neutral" of all the different types of foam materials but the firmness of a mattress and how much you sink into it can also affect sleeping temperature as well. (Firmer this will prevent you from sinking in retaining as much heat.)
The pocket coil core is a little further away, but it is one of the most breathable types of cores.... followed by latex, but it would be unlikely that most people would have any temperature regulation issues on either of the mattresses you are considering.
Generally speaking the more airflow there is around the body ... the better the temperature regulation of the upper layers of the mattress (including your sheets and bedding).
I look forward to hearing about your eventual decision.
