Was so looking forward to getting my new mattress and a good nights sleep after suffering with back and neck pain. Thought this product would be the answer to my restless nights and achey body. Received within a week of placing the order. Followed all directions as far as unpacking and unrolling. Allowed it to expand for at least 36 hours before trying out for the first time. Could not lay on back because left leg and arm got tingling and numb. Finally got comfortable on right side. Went out of town for next 2 days so it had even more time to expand. When returned tried sleeping on back again. No go again for 3 nights in a row. The 4th night was the worst. Couldn't sleep on back or side. Total left side went numb. Had to swap it out with my previous mattress just to get a couple hours of sleep. Hoping to get a refund but with the no return policy, I don't know. Maybe my mattress is defective and I'll get lucky. If not, that's *** down the drain.
