    • Turns any mattress into a dream of pleasure!

      I purchased this 4" memory foam mattress topper as a last effort to find something that would help me sleep better. I have been fighting a few horrible disease's called Fibromyalgia and Rheumatoid Arthristis and Chronic Fatigue for years and have never slept through the night. I'm only 44yrs old and too young to feel so old. The first time I put on my memory foam topper, I just layed there with no pain and instant relief. I didn't even get into my pajamas; because I fell asleep within minutes and to my amazement, slept all night long in the same postion. I woke up in complete shock and actually for the first time could walk to the bathroom without feeling stiff and bouncing off my furniture to just hold me up because of the pain. There's not a prescription from any of my doctor's that could have provided me with such relief. Now my condition is getting so much better because I am actually sleeping through all four stages of sleep that your body needs to repair your muscles, ligaments, tendons, not to mention your state of well being from having a great night sleep! I highly recommend this topper to everyone, especially people who suffer from insomnia caused by pain that awakens you when ever you move at night. With this topper, I find that I do not move. This is the best investment which was so cost effective, I could have ever purchased. There's not a sleeping pill in the world that can out do this topper! Thank You Overstock for saving my life. I was at a very low time in my life from suffering such chronic pain day and night. A good nights sleep keeps pain at bay during the day. WOW...what a dream come true. Sincerely, Carolyn

    • I swear by this!

      I were a bit skeptical to buy this topper as I know like all of you out there, a good night sleep is priceless... was just thinking of getting rid of my mattress which is still in mid condition and got one of those Tempur Medic mattress instead...Last minutes, I have decided to try this one out first...... oh my Gosh, it was so very comfortable..& .how good was it???? I almost missed work this morning and it is just not so me to do that... My advice, spend monies to buy this first if you are thinking about replacing your mattress... it is really really Great for a fraction of what could cost you..and it is made by Serta...can't go wrong with that.. Please note of one thing, the instruction of how to open this topper was packed in the bottom of the box, so I tried to manually rolled the topper opened and Opps, it was a mistake...I did open it, but it took a lot of of me to do so.... Please do not attempt to do that, just open the topper from its wrapper and let it sit on the floor for at leasat 24hour to air out the smell, but also make it easier to roll it open later. One happy and repeat customer...

    • good for its value

      I wasnt going to review this product until I had it for a while. 1 year later, here's my review: PROS: - with memory foam pads, the thicker, the better. 4" is the thickkest ive seen available out there. - decently priced. you get what you pay for - never woke up with a bad back, also considering i sleep on my side and chest - i sleep longer CONS: - it is heat sensitive: if it's cold in the room, it's firmer, if it's hot, it's softer and it's no longer a "memory foam" but a regular foam. - with that said, the area/shape you sleep on is not really a "memory foam" because of warm body temperature - the more it is exposed to the air (especially the edges), the foam turns from white to yellow like the rest of the regular foams - it's about 2" short from regular mattress size. but i suppose that's to make room for the fitted sheet to cover the mattress and the extra 4" thick memory foam. - im about 120lbs, the firmness is perfect. but i dont know about those heavier than me, because like i said about the heat/temperature problem, you might find your self sinking down making it a bit uncomfortable in the summer.

    • The future is now..

      Let me start by saying I am a real person. A co worker began talking about his $3K "T-Pedic" bed and really piqued my curiosity. I have a Latex bed and have been happy with it for some time. Well, I stumbled onto Overstocks' memory foam section and saw the 1400+ positive reviews on this 4" topper so I decided to see what all the gushing was about. Let me tell you what you can expect from this product. I ordered the topper on Sunday and it arrived on Friday. For only $3 shipping charge, that is really good. I am very happy with the Overstock shipping. I got a tracking number and could follow the package from manufacturer to my home. I read that some people had rips or stains on their toppers. Mine arrived just fine thru DHL. And I was pleasantly surprised that it had almost no smell. I mean there was a "new" plastic smell, but not anywhere to the point of getting nauseus. Maybe the 5 day trip let the product breath and air out before I got it. But I must admit, the first night my wife and I had to put 3 layers of sheets to not smell the pad when your laying on it. Also I noticed that the manufacturer was Advanced Urethane Technology (even tho it is sold with a serta label), so maybe the quality control issues have been addressed by Serta using this new company. So I drag the box to the master bedroom, and open the box and pull out the foam. It was rolled like a burrito . I centered it on the mattress and took off the plastic covering. As soon as it began to breath, it expanded, Fast. It took less than 10 minutes to fully expand. I did not Force it open. This is where I think most people put tears in their toppers. Moving the foam before there is air in the cell structure is a recipe for disaster. Once fully expanded, the Topper was not as heavy as I though it would be. It is a little tacky, so if you pull it with force, it "could" rip, but just don't pull it. I was easily able to just "lift and push" it into place. Oh and I'm happy to report that the King size really does fit our King bed. Maybe an inch off, but nothing to complain about esp. when i was reading some horror story reviews of 3 inch short toppers. Another thing I am happy to report, is that the topper isn't snow white, but pretty close. So it doesn't look unsightly. But you will be buying a cover for it anyway so what does it matter. So it's unpacked, centered, and expanded, now for a test. WOW. Now this is comfortable! I am happy to tell you that I am convinced that we are in a new era in sleep technology. I know it sounds corny, but I couldn't believe how nice it was. I would compare it to a feather bed but WITH support, or several layers of down comforters that don't squash when laying on it. The thing is, these pads are only going to get better than they are now. I made the bed and did the wife test. She loves it! I surprised her as she didn't know it was on our bed till I told her to lay down. And I know this is going to sound repetitive, but it's true, not 10 minutes after laying down, she was fast asleep! No lie! I was next to her and I just couldn't help but laugh because I had read reviews where the same thing happened to others. It's that comfortable! Ok, so now for some nitty gritty. You do have to adjust to it. It took me and my wife 1 night. It's mostly a mental adjustment more than anything. You just have to move different, and realize that you will be comfortable in one or 2 positions the whole night. My wife and I are back and side sleepers. But you almost get into a routine because your body gets numb or hurts every hour or so on a plain mattress, well no longer. The only time I roll over now, is for breathing reasons, namely if I snore too loud on my back, I'll move to my side, or my wife will move me. :) But once I'm there, I'm done. We are both sleeping more deeply and feel so good, we honestly can't believe it. I can say with honesty that all pressure is alleviated on this topper. No more pinched hips or bad circulation in the arms or shoulders. No more aches, stiffness, or soreness. We simply love this memory foam. Now I do have some advice for those out there who need a more robust topper. This 4" topper is great even at 4lbs. density. But If I didn't have to share my bed , the 5 lbs. density would be my next purchase. These are the only 2 densities, you should ever spend your money on. less than 4lbs wont support body weight very well, and your frankly, just skimping on topper comfort and durability. And stay with either a 3" or 4" thickness. This extra inch helps but is not needed if you have a higher density. I had my wife laying on her back and side and did some measurements and found that even on her side she only used 2" inches of foam and even less at her shoulders (these 2 points are the heaviest). We then measured me (6 ft, 180lbs) and I only used a half inch more at both points. Plenty of margin left in the foam to compress. We then checked for spin alignment, and it was normal. The foam curved exactly to our bodies contours. I had to see this to believe it, but now I have and it's true. So we haven't had the hammock feel with our topper. But maybe it is because of our weight and mattress condition. If your petite, this 4" 4lbs. topper will be a perfect fit as my wife will attest. However, if your heavier, go for the 5lbs. density and if that is too firm, then 4lbs is your answer, or vice-versa. Once your have adapted to how to move on this memory foam, you will love it. The real key is to just use your legs. If your on your back, just bring one knee up and push your foot down, viola! Your rolled over with no fuss or extra muscle needed. In the end, you should not think this topper will make a trash mattress good. It will still conform to the uneven, lumpy surface of your bottom mattress. But if you have a decent one but it's too hard, it will do miracles. For the price, you can't go wrong. Just be sure you don't want a denser topper first and you'll love it. Having this 4" memory foam topper has opened my eyes that $3K for memory foam bed is just a massive markup. You can have the same comfort with a decent mattress or platform bed and 1 of these dense (4or 5 lbs.) toppers for a fraction of the cost. A little reading and shopping will save you thousand$, don't you owe yourself a good nights sleep? This foam is fantastic!
