Very Happy – My husband and I are very happy with the comfort of our Ergo Flex Memory Foam mattress. It took us a couple of weeks to get used to the memory foam texture after sleeping on spring mattresses in the past. It is very comfortable and I have no more lower back pain. Real value for money. Good customer service and follow up. Happy Customer :-) Inexpensive, Comfortable We couldn't try the bed before we bought it.
