Chance 11" Organic Dunlop Latex Mattress

The Chance 11" mattress is a beautifully handcrafted mattress that incorporates the highest quality, breathable, 100% certified organic materials. It provides an incredibly comfortable, dry, cool sleep for one or two sleep partners, based on individual tailoring for individual sleepers.

100% GOLS-certified organic Dunlop latex provides highly flexible and supportive layers. Cores can be purchased separately, which ensures the mattress can be altered at any given time. The Chance 11" mattress is available with a choice of soft, medium and firm core layers. Queen and king mattresses feature 2 split middle layers, allowing each individual sleeper to choose their own firmness. To keep it simple, we show three firmness choices online, but the reality is the Chance mattress offers over a dozen possible configurations.

As part of our Zippered Forever Bed™ collection, the Chance mattress features individual layers of GOLS-certified organic latex that may be flipped, rotated and replaced at any time during the lifespan of your mattress.

The Chance 11" is easily the most luxurious fully certified organic mattress that TMASC has ever offered. It offers an unparalleled range of freedom and flexibility in firmness options and customization. It also comes with a removable cover that can be easily spot cleaned and aired out. No harmful, fire-retardant chemicals. Instead, organic wool is quilted into the cover and is an all-natural fire barrier.

The outer cover is 100% stretch-knit organic cotton, quilted to resilient and moisture-wicking organic Corriedale sheep's wool. Both sides of the cover are quilted the same way so body indentations can be reduced by flipping the mattress and re-building the layers.

Dunlop latex has a progressive feel, becoming firmer the more it is compressed making it inherently more stable feeling than other latex production methods.

The Chance 11" Organic Dunlop Latex Mattress is a Zippered Forever Bed™

A rational alternative to a typical trial period

Our mattress exchange policies have been carefully crafted to avoid passing on costs to our customers who do not require a comfort adjustment.

What is a Zippered Forever Bed™? It's a mattress with replaceable, modular components! Since 2008, The Mattress & Sleep Company has offered this style of mattress. Our stores in Calgary, Edmonton, and Sherwood Park each display and stock our modular mattress collection.

There are several unique benefits to a Zippered Forever Bed™:

• One no-cost component exchange between 30 and 120 nights on all Zippered Forever Beds. Learn more about The Sleep Sound Guarantee® here.
• A Zippered Forever Bed™ reduces the risk of choosing the wrong mattress. Most people are happy with their new mattress between 30 and 90 nights. However, many are unhappy with polyurethane pillow top and memory foam mattresses once they begin to settle in (typically in the 6-month to 2-year timeframe). While our highly elastic mattresses work well for almost everyone, occasionally we need to make an incremental change in firmness. The modular construction of a Zippered Forever Bed™ allows for these fine adjustments without resorting to returning the mattress and starting over again.
• Transparency. The ability to unzip and access the internal mattress components leaves nothing hidden or lost in translation.
• Easier to move. A Zippered Forever Bed™ may be taken apart and moved in pieces. Even a heavy king mattress is quite manageable and will fit in places that other beds may not.
• Individual components may be replaced separately (not all mattress materials wear at the same rate!)
• Many of the components found within our Zippered Forever Beds™ may be rotated and turned individually, resulting in more even wear and longer mattress life. This style of maintenance is considerably more thorough than the alternatives. One-sided mattresses may only be rotated 180° while traditional two-sided mattresses can be rotated and turned.
• Mattress warranties do not cover comfort. A Zippered Forever Bed™ may be changed at any time in the future at a lower cost than purchasing a new mattress.

When we say "forever" we really do mean it. Simply replace individual components as necessary. A Zippered Forever Bed™ features materials such as pocket springs, 100% natural latex, and cotton covers, all of which are available separately.
