This item was a major disappointment for me. While advertised as having a medium firmness, it was actually far beyond soft. So soft that that it began to cause joint pains in my knees and shoulders from sleeping in a curved (downward) position. That's how much give this has. Furthermore, nothing on earth could keep this thing from constantly sliding around on top of the underlying mattress. Every morning, it would be hanging of the bed by about a foot, and every morning I would have to correct it and re-do the fitted sheets. Overall, there is nothing positive I could say about this item.

very comfortable

I have only slept on this one night and know I can't keep it. 1) The foam itself is only at best 3 inches thick (on a 4" marketed topper - do better, Serta!) 2) It retains body heat and can make sleeping temperature extremely hot (unless that's what you want) 3) Mine also had that yellow chemical stripe on it - it's not urine as others have stated, I think it's from chemicals/being stored in non-temp controlled warehouses

Paid $149 at Sam's Club. I bought this a couple of months ago and it is extremely uncomfortable and it constantly slides off our bed no matter what we do. We end up having to pull it back onto bed few times a night. I have not slept well since I put it on our bed. We gave it time thinking it would relax or something but is worse over time not better. I don't know if Sam's club will allow me to return it, if not it will unfortunately be landfill!

Best nights sleep I have had in five years. It’s equally comfortable and supportive.

Comfy and stays in place on top of my other mattress.

This topper was extremely HOT n not comfortable at all. I returned it.

The topper is not providing any kind of improvement nor it improved our overall sleep quality

I like its softness and my back is not near what it was but it hot

Very nice and comfortable.
