I am very pleased with this mattress topper. It arrived earlier than I expected. It came in a medium sized box and was very light. At first, i thought, there’s no way it could have fit in there and there’s no way it’s this light. But when I opened it, I lay it on top of my bed and it slowly expanded like magic! This worked very well for me as it converted my uncomfortable old spring mattress into a sleep haven. Now I don’t need to spend hundreds of dollars into replacing my bed. Now my savings will go into presents for loved ones this Christmas.
