Is the ChiliSleep OOLER Sleep System worth the money? Read on to find out!

With the summer months upon us, soon many people, like myself, will be tossing and turning struggling to sleep in the heat. Sleep is not something I’m naturally good at anyway, but the hotter months with brighter mornings often mean less sleep for me. I saw an advert for what seemed to be an amazing product which will solve this problem – the ChiliSleep OOLER Sleep System – it was priced highly, at almost £800 but there was a 25% discount at the time, and with a 30 day sleep trial and free return, what could possibly go wrong?

Well, quite a lot! So, before you dash out to buy this product read this article because there are a LOT of unhappy ChiliSleep customers – their Trustpilot score is 1.9 out of 5 stars, “poor”. 86% of ChiliSleep customers rated them badly, with just 1 star. If only I checked this before splashing my cash.

Let’s start with the price – a hefty investment at £799 if you pay full price – I therefore expected a top quality product (and service). Delivery was quick. The product arrived in a nicely branded box… so far, so good. It was straight forward to setup. The app is easy to understand with nice settings. It was time to test the ChiliSleep OOLER Sleep System product out, exciting!

My experience using the ChiliSleep OOLER was an instant let-down. It initially felt amazing laying on the cool surface of the mesh mattress topper (which sits beneath your sheet, directly on top of the mattress). But after a short while your body warms up the area you are sleeping on. You therefore need to keep frequently moving positions to cool down and that initial cool feeling dwindles – the product simply doesn’t deliver. And for the huge price tag you’d expect it to WOW you!

The app has 3 settings, Silent, Regular and Boost mode. The thought of keeping cool on silent mode is great but you can forget that – I’m not even sure why the silent setting exists. Regular is just ok. If you want to experience any cooling at all, you need to use the boost mode, which is noisy. So we’ve got a noisy machine, producing average cooling temperatures that you can only experience if you keep moving (whilst trying to sleep). If this is not frustrating enough I woke up to find clear water patches scattered on the bed. It appeared to have leaked!! And on my expensive mattress!

I contacted ChiliSleep customer support immediately and sent pictures of the water on my sheet. I was advised at this stage to use a waterproof sheet between the ChiliSleep OOLER Sleep System “cool mesh” and the mattress – at this stage it was starting to become tedious and the thought of buying a luxury item which solves a problem with ease, long gone. 

Anyway, they kindly sent a new “cool mesh” and provided the following explanation when I pointed out it had leaked: “The system is a closed system and evaporation does occur. The amount of water that evaporates from our system can vary based on location, ambient temperature and humidity.” The second “cool mesh” did the same thing.

I was really disappointed at this stage. The expensive product wasn’t working as I had hoped and expected. It was frustrating with all these annoying issues. I decided to take advantage of the sleep trial promise and tried to return the item. This is when things got really bad…

I sent 5 emails over the space of 5 days and received just one reply asking for the order number, which they already had – it appeared to be a stalling tactic. I am yet to get another reply about returning the product and so at this stage, the 30 day return sleep promise is not valid (to me). It was at this stage that I decided to check out their reviews online. I couldn’t believe what I was reading!

One unhappy customer commented on Trustpilot:

“they said that the room wasn’t big enough for the ChiliPad to work – my room is 11ft by 9ft and the ChiliPad requires 11ft by 12ft.”

Another dissatisfied customer wrote:

“I’m an engineer, I measured surface temperatures, temperatures of the water in an out of the unit, etc. Then I dug into the actual cooling. The unit itself draws about 100w of power for cooling.(or not much past that). Even if it was 100% efficient, its not enough. The human body produces between 200-400w of heat. See the problem?”

If you’re thinking of investing and buying the ChiliSleep OOLER Sleep System, my advice is don’t. Partially, because the product doesn’t work well for me and many others, and their customer service is terrible. The price is far too high.

There is further confusion because the company has a separate UK and US website. Each site sells the same products at different prices with slightly different measurements. Bed sizes vary in the US compared to here in the UK.

It’s such a shame because this product could solve a genuine problem for many people. It appears however that there are variables which mean the product might not work effectively. If you want to contact their support for any reason, you will likely not get a reply.
