    Within a year was sagging where my spouse and I slept on both sides, and we were not extremely heavy. To get a Serta worker to come and inspect for refund, another fee was required...did not pay because enough already invested in bad product.

  • Disappointed in this purchase
    Verified Purchase

    This mattress set was delivered with wrong size box spring sets. The twin box springs combined were too wide for the bed; if you just use one, it was too small. I ordered this mattress set for an overseas delivery. By the time it got there and the mistake was discovered, Overstock, in their wisdom, told me the 30-day return period had expired.

  • Perfect compromise
    Verified Purchase

    A mattress that matches the firmness preferences of my wife and me has been difficult to find. She prefers a softer mattress and I prefer a firmer one. That is a tall order, and we have finally found a mattress that fulfills both of our needs. The Serta Alleene King-size Plush Mattress Set is the best compromise that we have found. It is truly firm enough for my tastes but not too firm for my wife's comfort, and soft enough to satisfy her but not too soft for me. If any other couples have similar situations, I would sincerely recommend that you try this mattress set. Service personnel that delivered the mattress set were in and out in no time, very efficient, and also took my old set when they left. Couldn't ask for more.

    While reading many reviews on this bed and also being told that Overstock has the best prices for great Mattresses , I went ahead and trusted that I would be happy with the Serta Plush. Many reviews said it was firm and comfy enough, They described exactly what I was looking for. So I purchased it and couldn't wait to have a good nights sleep. At last it finally came . The delivery company was so not client friendly and they tore a who;e in the corner of my mattress by dragging it through the dirty hall way. I didn't notice until they left. Folks please make sure to watch them put your items together before you sign anything. I figured there would be no problems so I left them alone to set my bed up. As soon as they left I was so upset to find my NEW mattress that I waited a month for was torn !! They ran out so quickly that I could not stop them. I called the Delivery company and the lady was basically saying " oh well you signed" you can call overstock and have them send you a replacement . I was so shocked that she was so rude ! I didn't want to wait another month to get my Mattress and I thought that they were so unprofessional. I just kept the Mattress .. Now 2 months later the Mattress is too soft and it's all ready caving in. I don't reccommend business with the Delivery Company , And I reccommend if you're looking for a Mattress to go to the Store and try them. Yes they are expensive but after all the headaches I went through it would be more worth it.

  • Nice but too Firm

    I was expecting a plush, soft mattress. I am so very disappointed. It is very hard. It feels like a rock. This would be a great mattress if you like firm. I am going to have to purchase a pillow topper. I am hoping that will help.

  • Not the best
    Verified Purchase

    I purchased the king set in July and totally loved it. It was the best sleep ever for a month. It now less than 4 months later and it already has body impressions. It's a great mattress if you want to sleep in a hammock. Not particularly a mattress I would purchase again. Simply put, I got what I paid for.

  • Great choice

    After testing many beds/mattresses in stores, we decided to try Overstock for products. For the price paid, the prompt & courteous delivery and set up, it is a great buy. Very comfortable too.
