    We had visited several stores in our area looking at mattresses. We knew just what firmness we wanted, knew we wanted a pillow top. Found this mattress on Overstock, price was great so we purchased it. It has lived up to everything we had hoped for. Been getting a great nights sleep ever since we received it.

  • Perfect mattress
    Verified Purchase

    So after being hounded by the predatory salesmen at our local furniture retailer, my husband and I left the store after 10 minutes and no mattress selection completed. We talked about going to other places to continue our search, but dreaded the thought of stepping into another store. We both like pillow-top mattresses, and he prefers a softer mattress while I like something with medium support. We decided to take the plunge and buy a mattress on-line based on description, without actually laying on it. I believe that this mattress is perfect for both of us. It has enough support for me where I don't feel like I'm falling into a sink-hole, and it is soft enough for him where he feels the "sleeping on a cloud" sensation. My biggest worry is the longevity of this mattress, as many inner spring mattresses develop low-spots and humps rather quickly. I will try to remember to post and updated review after several months to comment on how well it's holding up to standard use. My only other complaint is that I ordered the low-profile box springs, and standard ones were delivered. After setting up the bed I like the look despite the taller height I was trying to avoid, so I have decided not to send them back for an exchange. I received the bed within 10 days of ordering, and the delivery people were prompt and courteous. I asked if they would be willing to take away the old bed frame and mattress for disposal, and they were (however I decided to keep the old set for a spare bedroom). Overall an excellent experience, and I would certainly purchase this way again.

    I read many reviews on mattresses prior to purchase. I am not your usual on-line furniture buyer. I was a little afraid to purchase a mattress that I had not checked out in person. I am so, so pleased with this purchase. We have a new home so I purchased 2 sets for 2 bedrooms. After I received them, I ordered another set for the basement bedroom. The delivery was exceptional. Delivery was super fast and very professional. I would not hesitate to purchase other items from I am more than pleased!

  • Great set for the price!
    Verified Purchase

    Overstock's delivery with this item left something to be desired. It took 2 weeks to process the order, and another week or 2 to get a call from a delivery company with a date. If time is not an issue for you, then I would definitely recommend ordering a set from Overstock....Once it was delivered though I have no complaints. It is what it is! We love our big bed, and it's pretty comfortable. Definitely not what I would consider "plush", but the firmness, just like any new mattress needs to be broken in. The Eurotop is great and really comfortable. I'm considering getting a memory foam topper just to make it a tad softer.

    I do a lot of research before I purchase anything online, and I researched this bed online. The price as well as free delivery (sorry $2 delivery!) was great. The pillowtop is very soft, while the bed is not too soft, but not too firm. I have noticed foot pain go away with the purchase of this bed with the support it has given me. Great price for a King size, and the low profile boxspring too. Overall, I am VERY impressed with the price, and the customer service.

Questions & Answers

  • Q:

    "This item(13687365 ) Compare with Stera same brand(Perfact sleep liberation) but caushion firm (item13687357), what are differences between pillow top and cushion? I don't like very soft and hot feeling on my back while sleeping. Which item do you recommand? firm support and plush support? or any other item I can chose?"

    • A:

      Thank you for your inquiry. We found some tips we think you should keep in mind when purchasing the perfect mattress. Plush Mattress Advantages A plush mattress is most notably known for being a good compromise between a firm mattress and a pillowtop mattress. In fact, since a plush mattress offers a softer surface without compromising firmness, many couples purchase this mattress to suit one partner who prefers a firm mattress and one partner who prefers more cushion. A plush mattress offers a bit more give than a firm mattress but more support than a pillowtop. This type of mattress is ideal for side sleepers because it disperses weight while cradling the body of the person sleeping. Plush Mattress Disadvantages A plush mattress may have a less luxurious feel than a pillowtop mattress. Consumers who like to feel absorbed or "sunk into" their bedding will probably prefer a pillowtop mattress. Another disadvantage for consumers to consider is the longevity of the mattress. The added cushion on a plush mattress can cause the mattress to wear out more quickly than its firmer counterparts. Therefore, the life of a plush mattress may be shorter than what many consumers may prefer. Pillowtop Advantages This additional top layer makes a pillowtop mattress the thickest type of mattress on the market. Pillowtop mattresses are recommended for people who suffer from upper back and neck pain. Additionally, pillowtops are often preferred by people who like to "sink into" their bedding because of the luxurious feel of the mattress. The movements of each sleeping partner are isolated and absorbed by extra cushion of a pillowtop, which is advantageous to those who are often prevented from sleeping by the movements of their sleeping partner. Pillowtop Disadvantages Some pillowtop mattresses are so thick that standard bed sheets will not fit. Instead, they require special pocket sheets, which are specifically designed to handle the extra thickness besides being more $

  • Q:

    "I'm confused about the verbiage on the product detail and shipping & returns tabs...they are contradictory. Mattress Return Policy: Mattress Sets are non-returnable upon signature at delivery.

    • A:

      I am sorry, I am not quite sure where the 30 day Comfort guarantee is. But mattress sets are non-returnable upon signature at delivery. Mattresses are non-returnable if opened or taken out of their plastic wrapping. Upon delivery and before you sign the shipping receipt, inspect the mattress, foundation, or mattress set.
