I have had one of your beds for about 4 years. It is the best bed I have ever had. I cannot think of a better bed honestly. I like the fact that it is firm and at the same time comfortable.
My sleep definitely improved as soon as I got this bed. I remember that I had to get used to it for a few days or weeks.
I am also amazed that the mattress keep its shape and there is no hollow in the center that forms.
I hope you will never stop making them!
