I received this product as my second shipment - because the incorrect item was sent first. Customer Service was plesent and helpful with the exchange process. The first item I received was a 3" solid Memory Foam Topper - white in color. This item is blue-ish in color - due to the gel, I suppose - and it is an egg-crate topper. Shipping was very fast both times - and then I actually had two items to compare side-by-side! I placed both "3 inch thick" items side-by-side on my carpet to compare them, then asked my 28-year old daughter to make a good comparison for heat, feel, etc. She went into that room and returned after only a minute. I asked why she didn't take time to compare and she stated, "I feel like I am laying on the floor on the blue one". The solid topper, however, attracted my grandchildren, who thought doing "face plants" into the mattress topper would be a good ides - so they repeatedly fell face first into the solid white memory foam. Since both items I received had the same density of foam, the difference in feel can only be explained by two things: First of all, this item is nowhere close to three inches thick, while the regular memory foam was. Secondly, the egg crate reduces the amount of foam you are actually sleeping upon (because of the "air space" between the peaks). The bottom of the valleys in the egg crate are actually only about 1/4 inch thick (likely making it easy to tear if you need to move it around) - thus, once you lay on this topper, and your body compresses the peaks of the egg crate, the support is quite thin. If you really are not looking for much support - and don't mind feeling what is beneath this topper, then it is fine. If you would rather not feel what is beneath the topper, I found this one to be better: Slumber Solutions 3-inch Queen/ King/ Cal King-size Memory Foam Mattress Topper with Waterproof Cover. Be advised that the "cover" isn't a pillow-case type or zippered enclosure, but a fitted sheet type of cover.
