[This review was collected as part of a promotion.] A fantastically plush, supportive, mattress. It feels great, for myself it's exactly the right amount of support and softness that just makes laying on it a delight. Having slept on it now for about a week and a half, wake up no back pain, feeling refreshed, I'm not overheating or feeling like the mattress itself is retaining too much heat. The coils seem stable, they're not falling or feeling like they're not bouncing back to where they're supposed to be each morning. The service that dropped it off, definitely left something to be desired. But that's not the mattress of fault anyway The master itself is great, highly recommend.
