I have the windows open and the fan running, but somehow it is still too hot to sleep. Do you have any idea why? There are many reasons for this, and your current mattress may be one of them. Many great mattress brands are addressing these sleep issues, the latest being Hush's new Iced Cooling Tech mattress.

Launched this week, the Hush mattress (starting at $1,150) is "guaranteed to be three degrees below room temperature.

The new product is intended to keep you cooler throughout the night and help you fall asleep faster, according to Hush, because being too hot wakes you up more often and interferes with your sleep.

Previously known for its plush weighted blankets, Hush has developed the Iced Cooling Tech system, which consists of a top layer of phase change material and a graphite layer on the pillow top to draw heat away from the body.

While some memory foam mattresses are known to keep heat in, Hush aims to avoid this by using foam with gel bubbles that absorb heat without circulating it. We have yet to test the Hush mattress ourselves, but hope to test its cooling performance and comfort in the near future.

The TEMPUR-Breeze similarly guarantees 3 degrees of cooling, but is more than twice as expensive (starting at $3,299); the Hush, starting at $1,150, is the most affordable cooling mattress recently launched. For example, the new Serta Arctic Mattress has a starting price of $3,099.

Sleep giant Casper's Cooling Snow Series, which debuted earlier this spring, starts at $1,695 (read our Casper Wave Hybrid Snow Mattress review for a 4.5-star rated model).

The Hush Mattress also targets another sleep challenge: restlessness. Does your bed companion toss and turn throughout the night? If so, a mattress with motion isolation is your friend; Hush uses individually wound coils for motion isolation. Most boxed hybrid mattresses market themselves as motion-isolating, and if your restless partner is your biggest sleep obstacle, there are less expensive alternatives.

Hush mattresses are also designed with a zone support system, so the springs are firmer around the torso and lighter around the legs and shoulders to reduce strain. Its purpose? To wrap around the body and ensure correct spinal alignment (reducing neck and back pain).

It is compatible with a variety of bed bases, including adjustable beds and platforms, and comes with a 10-year warranty. An average trial period of 100 nights is provided for the mattress.

If you like the sound of Hush cooling mattresses, the brand is offering an exclusive launch deal that saves up to $201 on any size. With this discount, prices start at $950, with the queen at $1,499 and the Cal King at $1,899.
