Hey there BKr0n,
Welcome to the Mattress UnderGround.
John makes a good point regarding the cooling aspects of mattress sleeping. There are some caveats though.
While the IceTech and similar cooling protectors get plenty of marketing hype and some decent user feedback, the truth is that most cooling claims are overstated. These fabrics may feel cool to the touch initially, especially with phase-change materials, but they rarely deliver sustained, meaningful temperature regulation throughout the night. They can’t actually “cool” your body, at best, they slightly delay heat buildup, which is often enough to feel like a benefit for a short time.
More importantly, many mattress companies require a protector for warranty coverage, regardless of cooling features. In that case, the primary purpose of any protector should be moisture and spill defense, not active temperature regulation. Natural fiber options like cotton or wool protectors offer a breathable, comfortable layer that still protects your investment without relying on gimmicky cooling tech. If you’re a hot sleeper, your best shot at real cooling is improving airflow and room environment, not relying on thin mattress protectors.
Products like @Shepherds_Dream wool mattress protector or @TheCleanBedroom’s cotton protector, @SuiteSleep cotton protector, or sleep and beyond waterproof protector that is made from two layers of cotton and a PU breathable membrane.
So yes, get a protector if you need one, but buy it for protection, not for cooling miracles.
Hope this gives you a wider view of what you should be focusing on when protecting your mattress.
Finally, what makes folks hotter when sleeping is spoken about a lot here in this forum. @EuropeanSleep speaks to this quite often, here is a short post on the subject. He often explains that moisture and a humid environment is the reason why folks are hot on their mattress.
Just keep in mind, as mentioned, some mattress companies REQUIRE a mattress protector so not to void their warranty (whatever that means).
