    Sealy Advantage Cristal Plush Double Mattress 9021
    I was looking for a new mattress as I was long overdue for one and started going down the mattress rabbit hole - there are so many to choose from. So then I decided to try my go to - Appliances on Line. Whilst travelling recently I had slept on a Sealy mattress and loved so that together with reviews made me choose this mattress. It is the best mattress I have ever had - firm but soft at the same time. My problem now is I ever want to wake up! The fellow that delivered it was pleasant and efficient and took my old mattress relieving me of a problem getting rid of it.
