At the beginning of 2020 my husband and I decided to retire our mattress and splurge on a new one. Three mattresses later (all of which caused aggravation and discomfort to an existing lower back issue that I have) and four months later, we trepidatiously bought a dormeo mattress, but prayed it would alleviate the issues I was having...... our prayers were answered!  The mattress we purchased is a hybrid, with spring coils and a memory foam top; it is not too soft and not too firm, which is perfect for my lower back pain. Unlike the initial memory foam mattress, I actually sink into this one rather than just laying on top. It is easy and light enough to turn, asper the instructions, and the size is true to size standards; all of my original king sized sheets fit this mattress perfectly. Sorry for the long spiel, I'm just extremely happy with this mattress and my back is very thankful also.
