Depending on the model there are several layers which you can customize the firmness for your own personal comfort.
Green Sleep also have their own unique base which uses something called a dowel system.
It works similar to slats except that the individual pieces of wood are cylindrical rather than flat.
Because the dowels are thin you can fit far more of them on than you could slats.
This makes the mattress more responsive to where you place weight down, meaning pressure is eased and it is more comfortable.
A Green Sleep mattress uses natural latex from Indonesia to create the layers for its core and padding.
The latex layers are covered in a casing made from wool, silk and cotton. The cotton is organic, the wool however is not.
This is quite standard among high end natural mattresses because environmental grade wool is actually better in some cases than organic wool.Even Shepherd's Dream who are the standard bearer of wool mattresses don't use organic wool.
The silk is an interesting concept in itself. A silk worm spins a silk cocoon around itself and eventually turns into a both, just like a catipillar turns into a butterfly. In fact silk worms are actually caterpillars.
Regular silk production lets the silk worm spin its silk cocoon and then steams it, killing the silk worm. They then harvest the silk. The alternative is to let the moth break through the cocoon and fly away, and then harvest the silk. This means the silk is not quite as nice a color but it is more humane. A Green Sleep mattress uses the latter method.
The dowels for the base are made from Canadian maple and are completely untreated, with no sprays or additives used.
The mattresses that have innerspring systems rather than latex cores have high quality 9 inch pocket sprung coils that have untreated metal.
Green Sleep mattresses make a point of only using high quality ingredients. For more information have a look at this article on Green Sleep Raw Materials.
The Green Sleep mattress range comprises of natural latex mattress with latex cores or with innerspring cores. The innerspring cores mean you have a traditional spring mattress with the health benefits of being wrapped in natural latex rather than ordinary cotton. These are called the "Nature's Nest" range.
However for the full latex experience including relief from pressure points you should opt for one with a latex core. These are called the "Ergo Hevea" range.
Green Sleep Ergo Hevea Sienna
The Sienna is the simplest Green Sleep mattress. There are two 3 inch layers for a total of 6 inches. Each layer can either be soft or firm and it must be the same for the entire mattress, you cannot customize each side.
Green Sleep Ergo Hevea Sogno
The Sogno is a three layered mattress comprising a total of 6.5 inches of latex. The top and bottom layer are standard while the middle layer is customizable. The top is two inches of soft latex, the middle is three inches of either soft or firm latex and the bottom is one and a half inches of firm latex. The customizable middle layer can be different on each side of the bed.
Green Sleep Ergo Hevea Vimala
The Vimala has four layers with 7.5 inches total of natural latex. The top is one and a half inches of soft latex, the bottom is one and a half inches of firm latex. There are two customizable middle layers which can be different on either side of the bed. The lower one is three inches and can be soft, medium or firm. The upper one is one and a half inches and can only be soft or firm.
Green Sleep Ergo Hevea Dolcezza
The Dolcezza is a four layered mattress with a total of 9.5 inches of natural latex. The top and bottom layer are always the same but the middle two are customizable on both sides of the bed. The top is two inches of soft latex. The middle two layers are each three inches and can be in soft, medium or firm. The bottom is one and a half inches of firm latex.
Ergo standing for ergonomic and hevea brasiliensis being the rubber tree, Ergo Hevea is the latex core range.
The differences in the range as you go up in price are the total amount of latex and the levels of customization. The basic Sienna is 6 inches, the Sogno 6.5, the Vimala 7.5 and the Dolcezza 9.5.
The Sienna can have custom layers but the layers are the same on both sides of the mattress. All the others can have different configurations on either side.
Sienna at the lower end has just two layers, each customizable. The next model up, the Sogno, has a standardized top and bottom with a customizable middle. Vimala, the next model, has a standard top and bottom with two middle customizable layers.
What sets the Dolcezza apart is not just the fact it has more latex. The two customizable inner layers can be either soft, medium or firm. All the other models have the choice of only soft or firm. This gives you a greater flexibility to get the exact level of firmness that you want.
Limited Customization On Some Models
Only the top end model of the Nature's Nest range is able to be customized. With the Ergo Hevea range the top and bottom layers are not able to be customized. The top is always going to be soft latex and the bottom is always going to be firm latex.
Structuring the product line this way allows the top end products to be more desirable. However it is reasonable to expect that customization is going to result in extra cost while standard models will be cheaper.
Organic or natural mattresses are always going to cost more than your average mattress. But this one is right up there in terms of price. It's for a good reason - the thing is premium quality. You get what you pay for.
But in Savvy Rest you can get a natural latex mattress with more customization for a fair bit less. Although Savvy Rest is not as luxurious.
Green Sleep is comparable in price to Essentia. But with Essentia you are getting memory foam, not latex. And because they have the patent on natural memory foam they can charge higher because there is no competition.
Having said that if you are looking for the best in natural latex mattresses then this is something worth looking at because it is top of the line. Green Sleep is much better quality than other natural latex mattresses on the market.
