Subrtex Gel-Infused Memory Foam Mattress Topper - 4 Inch Twin XL, High Density Cooling Bed Topper with Breathable Removable Cover, CertiPUR-US Certified | Perfect for College Dorm, Guest Room & Home Comfort

I received my package yesterday. Unfortunately, I do not have the space to let this lay out for up to 3 days to air out and spread out.I pulled the box inside upon delivery. Let me say first, this is very heavy and not easily handled by a single 74 year old woman.I got it out of the box finally(LOTS of tape to secure that box) and pulled the heavily plastic wrapped topper down the hall to my bedroom and threw it on my bed, where my new-ish mattress that is a little too firm for my fluffy body, waited for it.If you have an elderly parent, neighbor, family member, tell them you will help them with this and don't leave it up to them alone. There will be a special place in heaven for you if you do.It is wrapped/rolled in very heavy plastic, layers of it because it is rolled up and folded in half in that roll up. They give you this fancy little plastic tool with a corner razor to just slice through it all.Don't kid yourself; get your scissors.I got all the plastic off and was sweating like a trucker by the time I had the topper laid flat and the adjustable elastic straps under each corner of the box springs.It got to air out 3 hours before I put new sheets on it.I did not notice any smell that would bother me as others have mentioned.It was comfortable last night and was able to roll over easily. I did not feel hot, but then we are not in summer mode yet.I got this primarily to help with the sweats a regular memory foam topper caused; I got the 3" instead of the 4" because I did not want to be stuck just in one spot all night as a fluffier person can find herself in on a regular thick memory foam mattress topper.I was able to turn over, get out of bed, was comfortable, helped with the the firmer mattress I now have, and over the span of one night, I can say I am happy with it.It is in a cover that has zippers so you can take it off and wash it and put the topper back inside when finished. I can honestly tell you, an elephant can have an accident on that thing and I will just have the whole thing disposed of and buy a new one. Imagine trying to get the 'gel infused memory foam' out of the cover and back in it. Nice, but again, not for the faint of heart or intellectually challenged. It just ain't gonna' happen.However, I stress, it is not for the weak or those without courage and determination, to get that box into the house, to get it out of that box, get the massive amount of plastic cut away as you try to roll it out, continually cutting the plastic and unfold it from its packing, then to wrap the elastic corners under the frame.Hopefully this will be the last time I have to do this until I am resting in the arms of Jesus and my bed is a perfect cloud.
