10 days review
I bought the Sleep Core after looking hard at Eight Sleep (too expensive in EU + subscription), Sleepme/Chilipad (doesn't ship to EU), and used Chilipad imports which can be sketchy. Qimora was the only real EU option in this price range with a clean design look.
After 10 nights, the experience has been very positive.
The headline news is that the dual-zone separation actually works. My partner used to sleep under 3 blankets while I was the one sweating with only 1. We now share the same duvet. That alone justifies the price for couples with mismatched temperature preferences.
The pad cools roughly 15°C below room temperature, which in my non-AC bedroom (24-28°C in summer) means a usable 18-21°C surface, exactly the comfort zone. The feeling is like getting into freshly made cold sheets, except that it lasts all night.
I've also noticed a +10-15% increase in REM and deep sleep on my Oura ring, but 10 days is too early to attribute it solely to the mattress, but it plays a part in it, that's for sure.
Shipping was done in 2 days, they overdelivered on this point and I was able to send it to a pick up point, package is super sturdy, and the design is very nice. It doesn't look ugly at all in the bedroom.
Two small points that could be adjusted: the control unit has no backlit buttons, so adjusting settings in the dark means using your bedside lamp.. The manual is quite basic, and would love to see more content around how to go around the settings, and progressively find the best option to adjust it for 2 people (finding your optimal temperature, etc.).
Noise is fan-level white noise, which is not an issue at all.
Setup is simple if you watch the video first (the color-coded tubes aren't super intuitive without it).
You'll need distilled water on hand, Qimora suggests to buy a 5L distilled water jug but only less than 3L are enough for the first top up. (then will have to be topped up every 3 months or so)
For Europeans who want the Eight Sleep experience without paying a fortune + subscription, this is currently the best option I've found.
