    • Where's the mattress
      Verified Purchase

      I haven't received my mattress. The shipping company brought out box springs with no mattress. I sent it back. Very disappointed with the whole process. Overstock has not made good on purchase as of the date. I'm extremely upset cause my husband and I took off to receive mattress. Not sure if I'll be ordering anything else of this magnitude from overstock. Also. Overstock and shipping company have very poor communication

    • Firm but a good mattress!
      Verified Purchase

      Delivery did take almost a month but we when it was delivered it was brought inside and set up by the delivery service. The professional delivery guys were amazed at how heavy the mattress (king sized) was. I was very glad they were moving it and I wasn't trying! We read a million reviews before buying this bed and have found it to be a good compromise for us. My husband likes a very firm mattress and I usually like a very soft mattress. This mattress is firm but with the memory foam topper it has worked for me. My problem was loose joints that ache because they slide around a lot. I haven't had joint pain in that way in the month we have has this mattress. My husband gets overheated and sweaty as this mattress holds heat quite a bit, but I think that happens with any memory foam mattress. I am always cold and haven't had a problem getting overheated at night. We will see what summer brings. Part of me misses my cushy bed that I sank deep into but we are overall both comfortable with this mattress which I didn't expect to ever happen. We were both very happy that this bed is American made and that we were able to find such a quality bed for the price. Is there a better bed out there? Sure, but I am sure it is at least twice as expensive. I expect this bed to last us a very long time. Please note- This mattress is VERY high. You will need super deep pocket sheets and you do NOT need the "boxspring". It isn't a boxspring it is quite literally a box and unnecessary. A piece of plywood would work just as well (we are going to switch it out) and won't involve climbing to get in and out of bed.

    • The Biggest Bed in the Universe
      Verified Purchase

      We've had this mattress set around 6 weeks and I absolutely adore it. It's beautifully made and came triple wrapped inside the same fabric that covers the mattress. Be forewarned though that this mattress and boxspring together make getting into bed a real challenge without a set of steps. Our shelties can no longer make it -- even with a running start. My husband is considering getting rid of the boxspring entirely and just setting the mattress on the supports for our sleigh bed. Don't know what I would have done if I had been buying this for my four-poster bed. I think it might have been as tall as the 17 mattresses in The Princess and the Pea. There's no disturbance when a second party gets into the bed so no worries about disturbing a sleeping spouse or partner. And best of all -- after years, no squeak, squeak, squeak, every time I move in the bed. The mattress has not sagged at all. This was just an unbelievable deal after looking at "discounted" beds that were 3 times the price.

    • mattress great
      Verified Purchase

      i was very apprehensive about buying a mattress set by web. but the serenity mattress is the best. set it up and slept for 14 hours. now as far as the delivery. i read all these glowing delivery remarks about how they set up the new one and took the old one away. NOT! we had a very short 130 lb driver who told us it was curb side delivery only. my husband and i helped him get the mattress in the house and set it up. as he volunteered to help us we tipped him very nicely. If you are older and can not wrestle a very large (19 inch) mattress and then the box spring after taking out your own box springs and mattress you may want to hire someone to come and help you out. it was a very hard task and my husband's and my back is much the worse for the savings. it was worth it however when you consider retail price runs 4-7 thousand dollars.
