    This bed offers great support. Delivery and price were very well. Purchased the lower box spring and it is a much more comfortable height than the traditional boxspring height. Would definitely purchase again.

    I was very hesitant to order a mattress set via internet. I decided to test some Simmons firm plush mattress sets in some local retail store first. After doing so I placed my overstock order. Delivery took a few weeks but it was worth the wait. I love this set, very computable with great nights sleep.

    Best purchase I have ever made. I sleep like a baby. I have had two back surgeries in the last year and I would not be able to sleep without this mattress. It is firm yet soft. Perfect thickness. It is like sleeping on a cloud. Highly recommend.

    My husband and I are both multi-position sleepers, and for years, my husband has claimed to need a FIRM mattress due to back problems. I have always preferred a softer sleeping surface, but since I don't have any back issues, we have always purchased FIRM mattresses, believing that was best for my husband's back. He continued to have back problems, and the only way for him to get a somewhat decent night's sleep was to sleep with an extra pillow between his legs. After having to sleep on several different firm mattresses (with no relief for my husband's back), I decided to start researching some PLUSH mattresses. After reading hundreds of reviews on several different PLUSH mattresses, I ended up choosing to purchase this mattress, and couldn't be happier. After the very first night, my husband said he "Slept like a baby" and no longer needs to sleep with a pillow between his legs to get a good nights sleep. He is waking up with less back pain, and I am loving being able to finally have my softer bed. It is nice and comfy and provides support no matter what position we're sleeping in. I highly recommend this mattress to any type of sleeper!!!
