    Can feel the springs in it
    Lost a star for being able to feel the springs from the first use - admittedly we have always been 'the princess and the pea' types and able to feel the least littlest thing like a crease in the sheets. Have had to buy a nmattress topper to avoid this issue. Maybe it's not as bad when not paired with the adjustable bed, but seeing as we did - yes we can feel all the springs. Otherwise it's a nice sturdy mattress, but the top should feel a little more padded for the price you pay.

    Very happy customer
    I am so happy with my new mattress and the great service I have received from Appliances Online. I received my delivery yesterday which went perfectly. I had included the option to have my old mattress taken away which I highly recommend if needed. Last night I slept on my new mattress which feels comfortable and supportive (the plush feel doesn’t take away from the much much needed support my back has been desperately needing). I previously had a Sealy Posturepedic which lasted me 16 years. This mattress is well built and I feel confident that it will last me over a decade. I can highly recommend Sealy mattresses and Appliances Online to all.
