We recently spent a lot of money on a new mattress but my husband opted for the firm support. This has proved to cause severe back and hip pain for me. I decided that I needed a mattress topper. I did a lot of research. I also needed one that was cooling as I suffer from hot flashes. I opted for the panda London topper. More expensive than a lot of other ones but seemed to fit my exact requirements. Add to that the 30 day free trial I figured I have nothing to lose. I also purchased 1 pillow. I’m for a penny, in for a pound. My husband tried my pillow and slept like a baby. So next day I ordered another. I am really pleased with everything so far. My husband was concerned the topper was going to ruin his love of the firm mattress but he is also loving the topper. My sleep has improved and I no longer wake up with a sore back. Very pleased.
