Our king size topper arrived via UPS in a manageable box; we opened it in our living room for expansion planning to leave it there for three or four days; we were concerned about potential odor since my husband is extremely sensitive to smell and I have allergies (we had concerns regarding out-gassing based on reviews we'd read about "chemical odor" associated with Memory Foam products). Within 4 hours the topper had expanded to full size and was minus ANY odor, it was immediately ready to put on the bed.
After three nights of comfortable sleep and my husband's low-back pain GONE, we ordered a second topper for our daughter and son-in-law as an early Christmas Gift. They were skeptical, but were game to give the topper a try. They absolutely LOVE the topper and tell us they would have purchased one long ago if they'd known this product existed. Their topper had no odor and they were able to put the topper on their bed within 6 hours of receiving it.

I ordered this mattress topper in California King. I am having problems with my hip and thought this might help with the soreness that I feel upon rising in the morning. So far, so good! It is so soft and comfortable, without being too soft and squishy. I've been sleeping it on it for about 5 weeks now and I'm sooooo happy with it. I sleep much better and wake up with much less stiffness and pain. I recently purchased a second one in size Queen for my guest bed with hopes that my guest will enjoy the same comfort while sleeping. :)

We have a shorter than normal queen mattress in motorhome and the mattress was harder than we like. This helped and fit better than I thought. Check your mattress size it will be smaller than a regular queen size. Does not seem to be to warm and has helped my hips and back pain. Would recommend.
