These were a horrible purchase! They smelled so bad, even after we aired them outside for 4 days, that we absolutely cannot use them. I put them in a storage closet and will one day use them to make outdoor cushions, but I don't think a person could ever sleep on them due to the strong chemical odor. In addition, they are far narrower than a standard size twin mattress. I do not recommend this product at all.
I purchased this to help my 3 month old baby sleep on her pack and play. I ordered the twin size, and as soon as we got it, my husband cut to fit in the pack n play (yesterday). Last night, when I picked up my daughter to feed her at 1am, I was shocked with that chemical smell. Had to strip everything from her bed (including blankets), as it had that strong odor. I will try to let it air out, as I cannot return it after having cut. I might also get a mattress pad to see if that would cover up that smell.
Bought this for my daughters sarah peyton memory foam mattress to add a little cusion and she loves it. Not to much but just enough comfort for her and the price was a great deal too! Not smelly,not dirty, came in clean and ready to go onto the mattress for added comfort.
The foam topper was purchased for a dorm room bed and is not enough to make the bed comfortable for my daughter. It quickly made an indent of her body and she feels like there is a hole in the middle of her mattress. Next time, I will buy a thicker one.
I bought my first memory topper a few years ago and loved it. I then added them to all the other beds in my house. Now I buy them as gifts They put life back into an older mattress. Once you sleep on one, you'll never go back to just a regular mattress.
Although the product is soft and helps with a less than comfortable mattress, I cannot get the petroleum odor to go away. I aired them out as was suggested, but they still smell. If you have a sensitive nose, do NOT purchase this product. If they were unused, I would have returned them.
