Ottawa's climate is genuinely extreme. Winters regularly drop below -30 with wind chill. Summers push into the mid-30s with humidity that makes the air feel heavier than the temperature suggests. Spring and fall arrive fast and don't stay long. The city runs on a thermal schedule that most of Canada doesn't experience, and that shows up in how Ottawa homes are built and how Ottawa people live in them.
Bedrooms in Ottawa spend half the year fighting to stay warm and the other half trying to shed heat. Forced air heating makes winter air dry. Central air keeps summers liveable but can overcool a room overnight. The result is a sleeping environment that shifts more than most people consciously register, and that variability affects sleep quality in ways that are easy to dismiss until you fix them.
Wool has been solving this problem in cold climates for a long time. It's worth understanding why.
What Wool Actually Does While You Sleep
Wool fibre has a cellular structure that absorbs moisture and releases it gradually. During sleep, the body produces sweat even in cool conditions. A synthetic cover traps that moisture against the skin. Wool pulls it away, holds it within the fibre, and releases it into the surrounding air over time. The result is a drier, more stable sleeping surface regardless of what's happening with the ambient temperature in the room.
In Ottawa's dry winter heating season, that moisture management works as a buffer against the desiccating effect of forced air. In a humid summer night, it moderates the clamminess that synthetic materials amplify. It's not a cooling technology or a heating technology. It's a regulating one, which is exactly what a city with Ottawa's climate range actually needs.
The Organic Cotton and Wool cover uses wool batting for this purpose. It's also the material that provides natural fire protection in the cover, without a synthetic barrier layer.
The DIY Dunlop/Talalay Hybrid: Built to Match How You Actually Sleep
The DIY Dunlop/Talalay Hybrid is an 11" build with a 7" Calibre Edge pocket coil base and 4" of latex above it. What makes it worth paying attention to in Ottawa specifically is how configurable it is.
The two latex layers above the coil base can be mixed and matched between Dunlop and Talalay, and across a range of firmness levels from Medium through to Extra-Firm. That means the mattress can be set up for a back sleeper who wants a more supportive feel, a side sleeper who needs pressure relief at the shoulder and hip, or a couple with different preferences splitting the configuration across a Split King. The layer exchange program applies to the 2" top layers, so if the initial setup isn't right, individual layers can be swapped without replacing the whole mattress.
The pocket coil base gives it a more traditional feel than a 100% latex mattress and handles motion across the surface differently. For Ottawa households where two people are on different schedules, including the many shift workers, night-shift health professionals, and early-rising public servants the city runs on, that characteristic is practically useful.

Frequently Asked Questions
Does the wool cover make the mattress sleep hot in Ottawa summers?
No. Wool's temperature regulation works in both directions. The fibre absorbs moisture from the body and releases it gradually, which moderates the clamminess that synthetic covers can amplify in humid summer conditions. It doesn't add warmth the way a thick insulating layer would. In practice, most people find a wool cover sleeps more consistently across seasons than synthetic alternatives, which is the more relevant property for a city with Ottawa's temperature range.
Can the DIY Hybrid be configured differently for two people with different sleep preferences?
Yes. The DIY Dunlop/Talalay Hybrid is available in a Split King configuration, which allows each side of the mattress to be set up independently. The two latex layers on each side can be chosen from different firmnesses and different latex types, Dunlop or Talalay, depending on what suits each sleeper. The layer exchange program applies to the 2" top layers on qualifying builds, so if one side isn't working after sleeping on it, that layer can be exchanged without affecting the other side. Sleep Majestic's phone fitting is the practical way to work through a Split King configuration before ordering.
How should I care for the Organic Cotton and Wool cover?
The Organic Cotton and Wool cover is spot clean only and should not be removed and washed. Washing will cause the wool batting inside to shift and can shrink the cover fabric. A mattress protector over the cover is a practical way to keep the sleeping surface clean over time. The zippered top provides access to the latex layers for the layer exchange program but is not designed for regular removal or laundering.
