What are the best mattresses for cold climates?

Here is a list of the best mattresses for cold climates, detailing foam density and firmness, temperature regulation features, and motion isolation with edge support for each option.

Koala Mattress

Why pick Koala Mattress?

• Two firmness choices for tailored comfort.

• Kloudcell™ foam and TENCEL™ cover boost airflow and cooling.

• Zero Disturbance® tech minimises motion transfer for restful sleep.

The Koala Mattress offers a flippable Kloudcell™ comfort layer with medium-firm and firm options, catering to varied support preferences. While specific foam density figures are not published, the construction focuses on resilience and comfort. Its open-cell Kloudcell™ foam and TENCEL™ Lyocell fibre cover aim to improve airflow and manage moisture, helping to regulate temperature for a cooler sleep environment. Zero Disturbance® technology is designed to limit motion transfer, which can benefit light sleepers and couples. However, edge support may be softer than some alternatives, potentially affecting comfort for those who sit or sleep near the sides.

Emma Comfort Mattress

Why pick Emma Comfort Mattress?

• Dual-layer foam supports various sleeping positions.

• Airgocell® foam and Fresh Air Cover keep heat away.

• Effective movement absorption for peaceful nights.

The Emma Comfort Mattress uses two foam layers to balance comfort and support. The top Airgocell® foam layer offers a medium-firm feel and promotes airflow due to its open-cell structure, assisting with temperature regulation—a useful feature in warm climates where overheating can occur. The firmer HRX foam base provides stability and contributes to overall mattress durability. Higher-density foams typically offer increased support and longevity, while lower-density foams feel softer but may not last as long. The mattress absorbs movement well, reducing motion transfer, and its edge support is adequate for foam construction, though some sinkage may be noticeable.

Ecosa Adjustable Mattress

Why pick Ecosa Adjustable Mattress?

• Customise firmness by rearranging foam layers.

• Gel memory foam and airflow design prevent overheating.

• Foam layers absorb movement for less partner disturbance.

The Ecosa Adjustable Mattress uses a three-layer foam system, allowing users to select from medium, medium-firm, or firm feels by rearranging the layers. While density specifics are not publicly listed, the foams are engineered for balanced support and durability; generally, higher-density foams provide better longevity and firmer support, while lower densities are softer but less robust. For temperature regulation, Ecosa incorporates gel-infused memory foam, open-cell structures, and ergonomic grooves, all designed to enhance airflow and dissipate heat, helping maintain a comfortable sleeping temperature. The mattress also performs well in motion isolation, with average edge support typical of foam mattresses.

ONEBED Onebed Original Gen3

Why pick ONEBED Onebed Original Gen3?

• Layer arrangement lets you personalise support.

• Latex and gel-infused foam promote cool sleep.

• High-density foam base strengthens edge stability.

The Onebed Original Gen3 mattress features a layered design with Dunlop latex, high-density viscoelastic memory foam, and a polyurethane foam base, offering adjustable firmness from medium to firm. Higher-density foams contribute to increased support and durability, while the latex and gel-infused memory foam layers facilitate airflow and help dissipate heat, supporting a comfortable sleeping temperature. Motion isolation is achieved through the combination of foams, minimising disturbances from movement, which is useful for couples and light sleepers. The sturdy foam base also maintains edge support, preserving stability and firmness across the mattress surface.

TEMPUR Original 25 Mattress

Why pick TEMPUR Original 25 Mattress?

• High-density TEMPUR® Material gives lasting, firm support.

• Open-cell foam and cool cover aid heat dissipation.

• Superb motion isolation for undisturbed rest.

The TEMPUR Original 25 Mattress uses high-density TEMPUR® Material, typically in the range of 4–5 lb/ft³, providing a firm level of support known for its durability and pressure relief. This density helps ensure longevity and maintains consistent comfort over time. To address temperature regulation, the mattress features an open-cell structure that helps promote airflow and a removable, washable cover designed for a cooler sleep environment. In terms of motion isolation, the TEMPUR® Material effectively reduces movement transfer, making it suitable for couples. The high-density construction also generally offers stable support across the entire mattress surface, including the edges.

Hugo Mattress

Why pick Hugo Mattress?

• Unique four-layer build suits many sleep styles.

• Breathable latex top disperses heat efficiently.

• Good motion isolation, though edge support is typical for foam.

The Hugo Mattress uses a four-layer foam construction, with natural latex as the top layer for breathability and responsive comfort. Beneath this, memory foam and transition foam offer pressure relief and a smooth feel, while a high-density support base enhances durability. The overall firmness is medium, around 6 out of 10, suitable for most sleeping positions. The latex layer aids temperature regulation by promoting airflow and dispersing heat, addressing concerns about overheating. Motion isolation is notable, reducing partner disturbance during movement. Edge support may be less robust than in hybrid models, which is a typical trait of all-foam mattresses.
