I have rampant fibromyalgia with multiple joints needing replacement & upper & lower back needing fusing. That said, I would heartily suggest buying this topper. I slept straight through on the first night (I'm usually fully awake many times during the night with all the pain) . there was no smell & only took a few hours to puff out. protect it with a mattress pad & sheet so, I did not notice any undue sweating from the foam. I recommend this fabulous topper to anyone in body pain. With just a few weeks of good sleep, my pain is much better & my life has been changed immensely!
This is a great 2 inch topper with a 2 inch egg crate shape, (4 inches total). I ordered it for a long twin RV sofa couch which I keep open all the time. You could feel the metal bar support through the couch cushions making it uncomfortable. My husband was skeptical that the foam would even help the problem, but just about every time he sits on the couch, I find him sleeping! The foam density is average for this type of topper. The density helps with keeping the heat retention low, but I also think that the egg crate design also aids with the cooling. The gassing off period was about a day. Since all the sizes were the same price, I got the largest size and cut off the excess using an electric knife. I covered the foam with blankets and use it to line the bottom of our 16 year old dog's crate. He seems to love it too!
I should have listened to the reviewer that said this IS NOT 4 inches thick. It's about 1/2 inch thick with big bumps. The bumps are far apart and the foam comes apart easily. I have it upside down (bumps down) on my mattress, an older mattress that dips in the center. This doesn't help at all. I have to sleep on the right or left side to be comfortable at all. I did order the king for my queen bed and cut off the excess. Then I put that extra down the middle of my bed. Turns out a lump in the middle isn't any more comfortable that a dip. So basically I spent too much money on an inferior product. But I kept reading "a 4 inch memory foam is muuuch better than 3 inch so I gave it a shot. I'm not thinking I would call this a 4 inch memory foam after all.
I have had this topper for about a year, and I don't know how I slept without it. I sit propped in bed for long periods of time due to illness, and it is a memory topper and I think it is forgetting :) But it wasn't designed to sit in the same place for hours. I will be buying a new one soon. I was waking up many times throughout the night and my doctor wanted me to have sleep study. I bought this, and discovered sleep! I was waking up all night because of pain, and this thing does wonder. If you have bone pain, arthritis, ect, get one!
This is advertised as a 4" topper, but the only part that is 4" thick is the peak of the hill; the valley of the foam base is less than 1/2" thick. That means that the average thickness of this topper is less than 2"! Over 50% of your memory foam cushion (that you paid good money for) consists of AIR! I bought this to use for cushions, and it was completely unsuitable. I switched it with the existing memory foam topper on my bed, since these items are difficult, if not impossible, to return. On my bed, this topper provides an extremely soft cushion, and is not like a solid memory foam topper that is much more dense. I have had toppers in the past with the undulating top, which is usually just the top surface area to provide some contour. However, this is a calculated effort to use less material and advertise it as something it is not. Completely unsatisfactory.
I did not receive a mattress topper that looks like the one in the picture. The picture and product description show a mattress topper that has rounded "bumps". What I received has much more pronounced peaks and valleys than the mattress topper in the product images. The net result of the much taller and narrower fingers of foam (as opposed to lower, more rounded "bumps") is that there is much less volume of foam in the topper. While the tips of the fingers may expand to a full 4 inches above the base, this California King sized topper only weighs 19 pounds. A full 4 inch thick topper that is 72"x80"x4" made from 3 lb per cubic foot memory foam should weigh 40 lb. This one arrived with a shipping weight of 19 lb. While the picture shows rounded, lower profile bumps that appear to reduce the volume of the foam in the mattress by maybe 25-35%, the tall, thin spike-like fingers on the topper I received clearly reduce the foam volume by slightly more than 50%. Heck, the low spots on this topper measure about 1/8 of an inch thick. Hate to say it, as I had high hopes, but this looks like a classic "bait and switch". The foam itself is very soft, as expected with 3lb density foam. However, the thin spikey fingers of the design combine to really reduce the effectiveness of this topper for comfort.
I ordered this by the photo on the site and what I received was nothing like the photo. looks like the solid part is about 2 inches but it is a lie , mine was about 1/2 inch and 3 inch cone lucky it even stays in one piece it is so thin. I returned it and ordered a different one and it was the same way do not recommend buying toppers without seeing them as you probably will not get what you thought you were ordering.
Our new, very firm mattress is good for back health. But, it's killer on the hips and shoulders when sleeping directly on it. That's where this mattress topper comes in. WOW, seriously, I never want to leave my bed anymore! It is absolute and complete comfort. The "bumps" feel weird for about 2 seconds, then everything is just bliss. Highly recommend this topper.
This is the 5th memory foam mattress topper I have purchased and it never disappoints the people I have given them to. My neighnor girl had spinal rodding and had a terribly hardf hospital bed and was in pain. We got her set up and she started sleeping in 4 hr sets instead of up all night in pain. My brother had vascular surgery and even with a water mattress could not get comfortable, now he wouldn't part with it. LOVE LOVE LOVE MINE!!! I sleep like a baby! ZZZzzzzzzzzz Great quality, price, and true to description.
This is a fabulous purchase for a waffle for your bed. I was having trouble sleeping on my side during this pregnancy without getting sore so I stead of purchasing a new mattress I thought I would give this a try. It's amazing. My husband loves it too and it's extra cozy :) it's a must buy!
I use this on my pull out couch mattress to make a really uncomfortable mattress very soft It is bulky and heavy but it makes such a difference on the bed that I don't mind dragging the big thing out when we have company I use a mattress pad over it to keep it in place
I was very excited after reading MOSTLY positive reviews about this product. Since my mattress is fairly old and I do have back problems from a car accident, I really wanted to getsomething less expensive than buying a new mattress. However, after putting it on my bed, I found it was actually a little too soft. I even tried turning the egg carton side down. I ended it up putting it on a guest bed(which no one has complained about)....but is a guest really going to complain??? There actually was NO smell like some of the other reviews said there would be. I guess I am more dissappointed in it than pleased.
If you price comparison bed toppers, especially for a cal. king, you'll see this 4" memory foam is heck of a deal. We bought our first topper in March 2012 and had to replace it Dec 2014. Over two years of comfort and many moons of use and I believe this to be great deal!
