10 Best Cool Mattress Toppers

The Silentnight Ultimate Deep Sleep 10cm Mattress Topper offers a luxurious 4-inch thickness, providing a cloud-like comfort that can rejuvenate any mattress. Its ultra-deep design ensures a cushioned, supportive sleep, thanks to the quilted cover with internal walls that keep the filling uniformly plump.

The material used is hypoallergenic microfibre, which is kind to the skin and suitable for those with allergies. Additionally, it is machine washable, making maintenance convenient and straightforward. Easy fit straps ensure a secure fit, so the topper stays in place throughout the night, which is a crucial feature for restless sleepers.

However, the product does not specifically mention any advanced cooling technology, which could be a drawback for those prone to overheating. While it provides soft support, individuals needing a firmer topper might find it less suitable. The product has high durability, evidenced by the 2-year manufacturer warranty, but its lightweight design (2.14 kg) might not be as durable as heavier options. It is an excellent choice for anyone looking to enhance their mattress comfort with easy maintenance and hypoallergenic properties.

The FRIDEKO Double Memory Foam Mattress Topper is designed to enhance the comfort of a firm mattress with its 11cm thickness, combining a 3cm soft foam layer and 7cm high-density memory foam. This layered setup helps distribute body pressure evenly, which can be especially beneficial for relieving back pain and improving overall sleep quality. The memory foam used is described as 'cloud air' foam, which resists sagging and helps reduce heat buildup, making it more breathable than standard toppers. The cover is skin-friendly, hypoallergenic, and removable with a zip, allowing for easy machine washing—a clear plus for maintenance and hygiene. The topper also features elastic straps and an anti-slip bottom to keep it securely in place, preventing unwanted movement during the night.

It offers good breathability and pressure relief, with a firmness level leaning towards medium-firm due to the high-density foam. This provides support for those who prefer it but may not suit users seeking a very soft surface. The foam should not be washed or exposed to direct sunlight to maintain durability, so care is needed. Its size fits a standard double bed well. This mattress topper is a solid choice for those seeking better support and cooler sleep without investing in a new mattress, especially if ease of cleaning and a secure fit are priorities.

The Silentnight Impress Memory Foam Mattress Topper is a 7cm thick, king-size topper designed to add comfort and support, especially for those who sleep on their back or side. Made from memory foam, it contours to your body to relieve pressure, providing a soft, sink-in feel that eases aches in your back and neck. Its extra depth helps rejuvenate an older mattress by adding noticeable cushioning.

One useful feature is the removable, machine washable cover, which makes it easy to keep clean and fresh over time. The topper is also hypoallergenic, making it a good option for individuals with sensitivities or allergies. It may retain some heat since it does not incorporate advanced cooling technologies, which could be less comfortable for hot sleepers.

The firmness leans more toward softness due to the memory foam construction, so it might not suit those who prefer a firmer sleeping surface. Weighing 3.5 kg, it is manageable and fairly easy to move around. This topper serves as a solid choice for improving mattress comfort with pressure relief and straightforward maintenance, though it may not meet the needs of those seeking enhanced cooling or increased firmness.
