Worth knowing: The mandatory subscription ($19/mo) after the first year is outrageous for a $2,500 product. Apple-level lock-in., The pump noise is noticeable if you're a light sleeper. They've improved it but it still cycles audibly at night., Returned mine after 3 weeks. The mattress cover made my excellent mattress feel like a mediocre one..
