Top product!Keeps you cool in summer and warm in winter.
The air conditioning at night upsets my respiratory system.
Top product! This mattress has really helped me stay warm in winter and cool in summer. And that’s given me a much better sleep routine.
I wouldn’t want to be without it now.😊👍
Sleep better with the mattress cooler,I bought the mattress cooler last year. I’m someone who gets hot very quickly at night (really quickly), and it gets incredibly hot in my house in the summer. The mattress cooler is a real lifesaver. Even my Whoop shows that I sleep better and recover more effectively when I use the mattress cooler. It’s easy to use and fairly quiet. Highly recommended!
I’ve had the KOZ-E Sleep mattress topper for 9…I’ve had the KOZ-E Sleep mattress topper for 9 months now and I’m really happy with it. What an improvement! I don’t get too hot at night – it keeps the temperature just right. I’d recommend it to anyone.
Finally, a full night’s sleep!,I’ve been using the KOZ-E Sleep every day for about eight months now and I’m very happy with it!
Personally, I really struggle with the fact that my body can’t release heat at night. Even after buying new sheets, a duvet and a mattress, I was still waking up at night drenched in sweat. But now that I have my KOZ-E Sleep, I sleep through the night and wake up in the morning without being sweaty. Lovely!
Customer service:
Over the past 8 months, the device started making a strange noise, but after a quick email exchange with customer service, they sent me a new one as a replacement and I was able to return the old one in the same box. For this alone, it gets a solid 10! In addition, the telephone customer service is also very friendly and they were able to help me with all the questions I had before purchasing the product.
Thank you, KOZ-E, for finally letting me sleep through the night!
The Koz-e Cool & Warm mattress topper is brilliant! I’ve been using the Koz-e Cool & Warm mattress topper for six months now. I haven’t slept a single night without it. In the summer, the cooling function is lovely, and in the winter, the warmth is great. It takes a bit of fiddling to find the right temperature, but it’s easy enough. I’d definitely recommend it!
A more restful sleep,We’ve had the KOZ-E Sleep Coolsleep at home for six months now. In those six months, there’s only been one night when I haven’t had it on. Now it’s winter, so I warm my bed up a bit and then switch it off. Occasionally, I set the temperature to around 24 degrees if I feel my body needs it. I now sleep under a warmer blanket, but sometimes that’s just a bit too warm, and the KOZ-E sleep helps a great deal.
In the summer, I set it to around 18 degrees, sometimes even a bit cooler, and it brings such peace. I wake up less often, and there’s less tossing and turning and restlessness. My legs, in particular, are always very warm, and they stay very calm now. I exercise a lot, and even then it helps with the restless legs and the heat I can feel in my body.
It took a bit of trial and error to find the right temperature, although the instructions are clear. It still varies from night to night. If I wake up now and feel hot, I switch it on straight away and fall back to sleep quickly and soundly.
I’m incredibly satisfied and even the noise is minimal. It sometimes even helps me sleep, like a kind of white noise.
I’ve been using the Wow mattress for 3 months now and…I’ve been using the Wow mattress for 3 months now and I have to say I don’t regret my purchase. I sleep very deeply and wake up without a stiff back (I have back problems). I can’t wait to use the cooling function in the summer. It’s a pleasure to sleep on it – even my wife has noticed that I’m much calmer in bed (when sleeping)😌
I highly recommend this product to people with back problems.
Staying under the duvet in summer and still keeping cool, I’m someone who can’t sleep without a duvet, but in summer that can get really hot. Even with the air conditioning on, I can still feel sweltering under the duvet.
I gave the KOZ-E mattress topper a go and wow! It takes a bit of getting used to, but it really makes a world of difference.
I started on the coldest setting, and that night I was actually really cold. My ideal setting is between 16 and 18 degrees. I no longer sweat (excessively) and I also sleep much better and more deeply (according to my sleep tracker).
I haven’t tested the heat setting, but I can 100% recommend the cool function to anyone who’s still on the fence.
