    My back loves this mattress
    Another quality product from Sealy. It delivers all the results it says in the product description. I have a bad back and this mattress relieves a lot of the pain I have. I read all the reviews and that is what helped me decide on this mattress. Make sure you do your research before commiting to buying. Good luck.

    Questions & answers

    Do the long singles you have zip together or have a topper so they can be treated like a King? Stgeph · 2024-01-02
    Hi Steph, these mattresses do not have a zipper or topper to combine into a King. However, we do have plenty of King mattresses available from Sealy and other manufacturers. Hopefully this helps =) Kind regards, Adam from Appliances Online. AdamD, Appliances Online
