"Score amazing naps (and better mood as a result) with this temp-controlled/game-changing sleep system. Another Brit favorite, it uses water-based heating and cooling to give you the perfect temperature for much-needed deep sleep."
"Smart mattresses can cost thousands of dollars, which doesn’t really make sense to buy if you already have a perfectly good mattress. The Cube Sleep System brings much of that intelligence to your bed at a much more justifiable price."
" The team has developed sophisticated cooling technology to ensure you're sleeping at the optimal climate for deepest rest. And the best part is that you can set your side of the bed at one temperature and your partner's at another — perfect for hot and cold couples!"
"A system that is absolutely custom to your exact sleep temperature, and that bespoke approach is a massive selling point now more than ever before."

"Sleep is important in these days of isolation. ⁦⁦ @tferriss ⁩ The Cube recommendation has been a game changer for my wife and I over the last year!"
Worth It!
"My husband and I are both hot sleepers and this system has stopped our search for a permanent sleeping solution. Worth every penny. We consistently sleep through the night and haven't had to wake up sweating since the pad went on. System runs quiet and the pad is not uncomfortable."
