Have had one for years... love it!! Has a mattress cover that gets washed regularly, no sore back in the morning, when its cold it is stiff but body temp warms it quick. Don't care for the "orthopedic" pillows though, i would get the regular shaped ones made of the same foam. You are good to go when it comes to doing "it".
But I have been married for 20 years so those moments are few and far between.
