I've had my mattress for a week now and WOW! what an awesome and comfortable mattress! I also purchased the ERGO Extend Smart Base - adjustable bed base - which is also awesome! I've read where allergists, ENTs, etc. recommended an 'adjustable' base for allergies - and LOVE my adjustable base as it has helped my allergies from not sleeping flat or with more than one (1) pillow! Finally I purchased two (2) Cloud Breeze Dual Cooling pillows and these, too, are awesome! No BACK or NECK PAIN from using more than one (1) pillow. The mattress, adjustable bed base and pillows have been GREAT! Improved my sleeping SUBSTANTIALLY! Should have purchased sooner at my brother's advice!
