Selling our used, but still like new Purple 3 hybrid mattress. It is a regular king size. We are looking at another mattress to replace it. It is a great mattress for those who need more of a soft mattress than firm. It is adjustable base friendly and has good ventilation through the mattress to keep you cooler through the night. Paid well over $2300 for it new. Will need to be picked up, and it is very heavy (you may need help to move it). Comes from a smoke-free home of healthcare professionals. Contact me for any other details.
