I have the mint in king size with 2 king size pillows. I bought the box set from tuft and needle as well. The box set is so heavy duty and the mattress and pillows are amazing. I never want to get out of bed in the mornings because I am so comfortable!
The first week I was not able to get any sleep on the mattress, back pain and just uncomfortable, the start of this has been better, going to give it some time. Also no one came to recycle our old mattress. Still trying to decide if we will keep the mattress or if we buy the caspe wave.
