Soak & Sleep Wool Mattress Topper Review: Does It End Night Sweats? (2026)

I recently tested the Soak & Sleep New Zealand wool mattress topper, hoping it would be the solution to my persistent night sweats. As someone who often feels cold when getting into bed and frequently wakes up drenched in sweat, I was intrigued by the temperature-regulating properties of wool bedding. The mattress topper arrived in a square plastic and fabric zip bag, with elastic straps that securely hold it in place around the mattress corners. Despite its thin 2.5cm depth, the topper didn't require any expansion time and could be shaken out and placed directly on the bed. The quilted design prevented the wool from bunching up, creating a smooth and even sleep surface. The wool filling provided just enough cushioning for my knees, hips, and lower back, easing any aches and pains.

One of the most impressive features was its temperature regulation. Wool is naturally hypoallergenic and has temperature-regulating properties, absorbing and releasing humidity to keep you at the perfect temperature. Since adding this topper to my bed, I haven't woken up from overheating, even in different hotels and at friends' houses. The wool filling also offered a fine layer of comfort, adding a soft, springy top layer to my mattress.

However, the topper's thinness made it appear more like a mattress protector than a traditional mattress topper. It didn't provide the additional pillowy softness I expected from a wool mattress topper, especially compared to the Woolroom Deluxe mattress topper, which is also made of 100% wool but is 4-5cm deep. The Soak & Sleep topper struggled to compete with the level of cushioning other toppers could offer, and it provided zero motion isolation.

Despite its limitations, the Soak & Sleep mattress topper is well-made and comes with a 5-year guarantee. The elastic straps are secure and strong, ensuring the topper doesn't budge. The wool filling is machine washable, but professional washing and drying are recommended to prevent clumping due to moisture. While it's an affordable cooling mattress topper, it's more of a turbocharged mattress protector, and its thickness makes it expensive for the level of support it provides.

In conclusion, the Soak & Sleep New Zealand wool mattress topper has been a game-changer for my sleep, ending my overheating nights and adding a luxurious layer of cushioning. However, it's not ideal for those seeking extra support or a thicker topper. If you're looking for a thin layer of extra cushioning and have access to a tumble dryer or professional cleaner, this mattress topper is worth considering. Personally, I think it's a great investment for anyone struggling with night sweats, offering a natural and effective solution to regulate temperature and improve sleep quality.
