King Size 4 inch Thick, 4lb Density Gray Visco Elastic Memory Foam MattressPad, Bed Topper Made in The USA

I purchased this product because my girl friends bed kills me. I would wake up sore and feel like someone had beat me with a bat all night long. Now that I have this on the top I sleep great and wake up feeling great. It is very soft. I first placed this on the floor and laid down on it to see if I would sink down and touch the floor. I weigh 285 pounds and I did not sink all the way down.....which is good and much better than I thought.I own a posterpedic bed that I paid over five grand for and this simple 4" foam feels better. Had I known this sooner I could have saved myself a lot of money.One suggestion I would make is to buy this product in 2" inch increments.I honestly think the 4" is to soft. I wish I had bought it 2" thick.....and tested.....and if I needed more ........then buy another one either 1" inch thick or another 2" inch thick item. This allows you to get the right amount of comfort because if you go all in and get the 4" inch like I did. If you find it is to soft.....there is nothing you can do about it.....however if you bought 2" inch thick and put another 2" on top and found it to soft......you simply remove the top 2" inch section. Just food for thought.Overall I love this product.

LOVE! This is absolutely a steal for the quality and thickness! I spent a little over a week researching different toppers and thicknesses and honestly felt as though my brain was going to explode. So ill keep this short and bullet pointed- 4 inch thickness- This is fantastic if you do not want to feel your current mattress, it is comfortable for my husband who is a bigger guy 6'3 280lbs- Like sleeping on a marshmallow- if your looking for a soft topper that you sink into this is it- Memory foam- yep its 4inches of fabulousness- Opening the topper- Be gentle, its pretty easy to open it up fully especially if you lay it out and let it breathe a bit- Smell- there was a slight odor when airing it out but it wasn't that bad to be honest. I sprayed it with febreze and that helped immediately- Letting it fluff up- we only had to wait a few hours for it to air out and open up completely but we live in HI where its fairly warm and humid so I think this helped, because when I was first opening the topper the foam was fairly cold and a bit stiff- Moving the topper- Dont be a moron and think you can move a 4inch king topper on your own, my husband and i rolled it up like a taco and moved it into our room with no issues and no ripsOverall I am 100% happy with my purchase.

This is a little small. The king is 75x78, but a king mattress is supposed to be 76x80. Given the price, I'm disappointed that they shaved off some inches to, presumably, cut costs. The 4 inch 4 pound king is pretty heavy, which speaks to quality. However, it isn't quite as firm as I'd like (i.e., you sink in to it too easily). I'll keep it. I'm adding this to my previous set up of 4 inches of traditional foam and 4 inches of memory foam (another brand), which was insufficient and I was sinking to the bottom. Now with 12 inches of foam, including this item, it feels much better. But don't fool yourself into thinking that this item alone would be sufficient as a mattress. It is a topper, not a mattress. I'm a side sleeper with some injury issues, so memory foam is necessary for me. A temperdedic (sp?) is too expensive for me given that I can put three toppers together to create a similar effect for dramatically less money. Bonus tip: if you have a slat bed (e.g., Ikea), and you're creating a memory foam "mattress" out of toppers, you can use cardboard boxes between the slats and the mattress so that you don't break the slats. Otherwise when you put a knee down on the bed, you'll break right through the cheap Ikea slats (learned that the hard way years ago).

This is REAL memory foam; buy this!! No actual issues with the product as listed so far.If you are smaller (150 lbs or less, roughly), I would recommend a 3 lb density or so but 4 inches (at least) is definitely a great thickness if you're a side sleeper.My wife is a lightweight side sleeper with wide bony hips that caused a pressure point with the 4 lb density so we also have a 2 inch cooling memory foam on top of this pad that is very low density (around 2 lb or less). The bed really depends on the body but this pad was totally fine for me (male under 150 lbs) all by itself. The additional soft top pad makes the mattress great for both of us. Multi-layers may be the way to go! Especially if you want real memory foam support, soft feel on the top layer, and a cooler sleep.No they do not slide at all. No the smell is not bad; let it air out.*The bad reviews are mostly due to pads being defective. It was probably a bad batch. Just register your warranty. Mine is still fine after moving it between rooms a lot.

We had this for three years, after three years there is no sign of degradation that I could see, so that is positive. The problem is that it is just too soft; it feels comfortable when first laying on it, but since you go right through it, it is more like laying in a hammock than a bed. I placed it on the floor to see what it was like alone, and it basically offers no support at all, any point (shoulder, hip, elbow) is in floor contact, so if you have an uncomfortable bed, this is unlikely to help matters in my experience. we are side sleepers of average build, so take that into consideration. It is heavy, and since it has no cover, we ended up putting a mattress pad on it just to protect it.
