I love these so much. After buying the first two I ordered another one for the motor home and we love it just the right amount of soft since it does get a little harder when you camp in colder weather but it works great and I would not change anything about this product. Had no bad odors to speak of a faint smell for a few hours and it was gone and ready to use the next day. If you like to be cradled in softness this is the mattress for you.
The quality of this memory foam is very good in that it is consistent in both sizing and thickness. It is also of even light color and (happy surprise!) there was no bad odor to air out after taking out of box. We left it lying flat in the garage for only 3-4 hours and it expanded to the correct size and shape in that time. However, it is much less dense (lighter in weight) than I anticipated. Therefore, it is softer and quicker to react to depression than I had expected. Since we got the 4" rather than a 3", this lighter and softer quality is not of major issue. We have had a harder 3" before, and this is comparable to that one, perhaps because of that extra inch.
I love how the topper feels when I crawl into bed, it make me want to never ever get out of bed ( two thumbs up) I don't like how it is yellowing because it looks kind of gross.(two thumbs down) I would have given it five stars but can't because fo this reason. I have had thinner toppers before and they have all turned yellow, not sure why they do this and I wish something could be done about it, but it does not change the way that it feels. I recommend memory foam to everyone (and I have!)
I put a mattress and no boxspring into a water bed framed bed. It was very hard and uncomfortable. The solution to the problem was adding the 4 inch memory foam topper. All of my houseguests rave about how well they slept in that room. I recommended that they put a memory foam topper on their bed at home for a good nights sleep. Excellent buy!
I had a memory foam on my bed that was 3" and had originally purchased this for the spare bedroom. When it came liked it so well switched it out for one on my bed. I am very happy with it. Also surprised that adding 1" made that big of difference in comfort. If I need to order another one will order this same one worth the little extra in money for the 4".
This four-inch mattress topper is exactly what's advertised at about half what they charge on other websites. It is extremely comfortable and of good quality (very heavy). The only negative I've experienced is the fact that on the Queen size topper (the one I purchased), it is not flush with a Queen size mattress. There is about an inch of mattress all the way around the topper, which isn't a huge deal when you have sheets on, but as a tall person I miss that extra inch! Otherwise, excellent product.
I bought two of these as early Christmas gifts for my parents, both of whom have reached the age where a full night of comfortable sleep is rare. Both managed full nights several times since getting these, and my father, who has constant neuropathy pain, said it is much improved. Small miracles.
