  • Best Mattress Set Ever!

    My husband needs hip replacement at a very young age and has been in considerable pain. This mattress is recommeded by the National Orthopedic Foundation, so I thought it was worth a shot ordering it over the web. Since we bought this mattress set, he is experiencing much less discomfort at night, and it is much less pain in the morning. This was a very good purchase.

    • How did the color on site compare with the actual product? Fine
    • Please tell us about the quality of the product. The mattress and foundation are supportive, well constructed and extremely comfortable. A mattress salesman told me once, if you want a mattress that lasts, sit on the very edge of the bed. If it sinks way down, it's not a mattress with a long life. This mattress doesn't budge when I do the "edge of the bed" trick!
    • How accurate was the on site description of the product? Extremely accurate description on the Overstock.com site.
    • Would you recommend this to a friend? Yes
  • Excellent mattress set

    I was nervous about make such a large purchase "sight unseen". However, we live in rural Maine, couldn't find a comparable price for the quality locally, and didn't want to spend time and money driving to the city to shop, only to have to then deal with delivery issues. My husband and I are both delighted with the mattress set. It is firm yet comfortable, as described. Also, kudos to Overstock for excellent delivery service. We were notified and kept informed, even when a snow storm interfered. The delivery personnel were professional and efficient. Thank you.

    • How accurate was the on site description of the product? Very accurate
    • Would you recommend this to a friend? Yes
  • just what the doctor ordered...

    I've had 4 shoulder and 1 neck sugeries. this mattress takes care of all my needs.firm but still very comfortable.

    • Would you recommend this to a friend? Yes
  • Great mattress, great deal

    We knew we were taking a risk by buying a mattress online without feeling it in person, but I'm so glad we did. We love our new mattress and are also very happy with the price (and free delivery!). The mattress came on time and we were notified beforehand so we knew to be home for the delivery. I am on Overstock again right now to buy another of the very same mattress for our other home. I highly recommend this product.

  • Great purchasing experience

    I purchased the king-sized mattress set as a birthday gift for my son who lives in another city. I experienced sticker shock when shopping for mattresses that were on sale with retailers. So I thought giving him this special gift was not an option for me. The Serta mattress is top-of-the line and cost 1/4 of the ones on sale in stores. The delivery men set up the mattress and foundation and removed all packaging. But most important to me, they hauled away his old one, which my son was not in a position to do. Thank you, Overstock, for making this the best purchasing experience ever!

  • Serta Perfect Sleeper Liberation Cushion Firm King

    We are very happy with our purchase of this mattress set. The price was more than competitive and the shipping experience (free, white-glove) was great. Be advised that this is a VERY FIRM mattress; if that is not what you want, you will need to research further.

    • Please tell us about the quality of the product. very good so far
    • How accurate was the on site description of the product? I would describe the mattress as extra firm.

  • Bed is sinking after 1 month

    I purchased this mattress based on the positive reviews. Unfortunately, after one month of receiving it, it's already sinking on both sides where my husband and I sleep. I've owned many other brands of mattresses, and this is the poorest quality I've ever experienced. Don't purchase this mattress!

    • Please tell us about the quality of the product. Poor quality

  • Just what we wanted!

    Just as described, very firm, which is what we wanted. We will most likely add a foam topper for a little bit extra cushion. Shipping was flawless, took about 3-4 weeks to arrive.

    • How did the color on site compare with the actual product? Perfectly
