It is the most expensive piece of furniture I own, but it changed my life a LOT. Been a skeptical since its promoted on youtube as well, which usually isn’t a good sign. But after 5 months of usage, my sleep is on average 30min longer for same time in bed, and I am way more comfortable. Also, I already saved 1/3 of the price just on ac costs (i stopped running ac completely and just cool the bed), and once winter time hits, I will not have to heat the appartment so that will be good again (it rarely drops below 12 here, so noone has heated floor or radiators or insulation for that matter)
