Not a complete fan of the mattress. It's just average.

When sleeping on the mattress in summer days it does run very hot. Mattress has been used only for a year and already has quite a bit of sinkage when sleeping along side my spouse. She hates the mattress and prefers to sleep on the floor. Purchased the medium firmness. Should have gotten the harder firmness. Buying the high end pillows from Nest Bedding did not help with the back or shoulder aches. If I could return the mattress I would in a heart beat. Rather spend extra money on well known competitor in the memory foam business.
