I bought my first memory foam matress from hypnia several years ago to replace a king sized matress in my rental property. I only had the chance to sleep on it a couple of times between tenancies, but was suitably impressed. When the four other matress needed replacement, I went with hypnia. I've had good feedback from the tenants. When it became time to replace my matress, it was a no-brainer, just the right amount of comfort and support
