  • Super firm!
    Verified Purchase

    Just as it was described! Seems like it took a long time to get here because of it being a freight delivery so if you want it tomorrow it's not going to happen but the bed is exactly as described. Super firm and super comfortable!

  • NOT VERY FIRM AT ALL! My back hurts sleeping on..
    Verified Purchase

    NOT very firm at all! My back hurts sleeping on this bed!! Way too soft for me. Very disappointed! I was looking for something extra, extra firm (flat & firm like sleeping on the floor) and this bed is way too soft! It is more like a mild firm or luxury firm to me, not extra firm. So so disappointed and I spent over a $1,000 on it! :( Maybe buying a mattress online is the wrong way to go?!?!?

    We have had our new mattress and box springs for only a few nights. Just to clarify, I need to sleep on a very firm mattress or my back will hurt IOW: I don't have back issues unless a mattress is too soft. We have walked in many stores, laid on the bed and made our choices. Our last mattress was a Sealy - very expensive plus we had delivery and haul away charges. Within two months it began to hammock. How disappointing. By the end of a year, I was sleeping on an air mattress just to avoid the Sealy. Our new Beautyrest is an extra firm. We are very impressed with it. I will write a review in about six months to let you know how it is holding up. So far we love it. FYI: I purchased a very good mattress pad to use with the mattress. My main purpose for this review right now is to express how impressed I was with the White Glove Delivery Service provided by Overstock and MXD. Sean and Paul, the MXD drivers, were extremely accommodating and very pleasant to be around. I can't express enough how much we appreciated them. Good Job and Kudos all around. Living in a rural area, I order lots online and especially from Overstock. My life is much easier because of the service we receive from Overstock.

    Back pains have reduced significantly.I like firm beds with pocketed springs to minimize movement felt when other person moves. Daughter loves our mattress too. Wish I could have purchased with box springs since my bed is a platform bed.
