Our very expensive pillow top mattress, at 15 years-old, had become too soft and uneven. More often than not, I would wake up with a sore back and joints. I ordered this topper hoping it would even out the mattress surface and provide a bit of support for my back. I was wary, without being able to try it out before ordering, that it may be too soft, but it has turned out to be the solution I was looking for. The mattress now has a comfortable uniform surface that evenly supports my joints. My sleep has improved greatly because of this simple, and economical addition. It arrived earlier than expected, and was securely shipped in a small package. All I had to do was unpack it, unroll it, and let expand for 24 hours. I was pleasantly surprised that there was no odour. Great purchase, and highly recommended.
