The Slumber Solutions 4-inch Memory Foam Topper was delivered to me via UPS surprisingly quickly. I pulled it out of the packaging and allowed it to unroll, following the instructions, and allowing it to air out before sleeping on it. That was hard! I had read some other reviews about the smell from the foam. If you allow the topper to air out, as the instructions say, you wont have that problem. After 48 hours there was no longer any smell to my topper. I put it on the bed with the egg-crate points facing up, and slept on it for the first time last night. I didn't want to get up this morning! I also have a memory foam pillow, and have slept on a memory foam mattress in the past. This is the first time I've tried a memory foam topper, though. What I like about it is how soft it feels, yet it's also supportive. The small of my back is cradled instantly and comfortably with the foam. It takes a few minutes for other memory foam to conform to your body. Perhaps the egg-crate points on this particular topper help with that. I was a bit concerned that you'd be able to see the points showing from underneath the sheets, but that is not the case. You cannot tell that an egg-crate looking piece of foam in under there. The price here is unbelievably low, too! I checked my local area and couldn't find anything even close. The nearest I got was a 3" topper for twice the price. I'll be a regular shopper here!
