I am extremely happy with my Hills Bamboo Natural Pocket Sprung Mattress. I didn't know such a mattress existed so when I saw this on Wayfair I just knew it was for me. I have suffered for years sleeping on a memory foam mattress that was like sleeping in a saucer, absolutely hopeless and extremely uncomfortable. To find a mattress made of natural fibres is like a miracle, I love my new mattress, thank you
