My wife and I purchased 2 mattresses, 1 for us and 1 for our 5 year old son. Aside from the fact that in about 1 week my wife and I no longer have back and neck pain, when I go in to my son's room in the morning his head is on the pillow! Anyone who has a little one likely knows how much they move through out the night.
We purchased a Tuft and Needle mattress last September and we lost it in the Hurricane. We have since purchased another one and we love it just as much! Super customer service and an excellent product!
