Ecstasy
I did a lot of research before pulling the trigger on the Ergoflex and actually paused on buying a mattress for 3 years.
I went and tried out hybrids and memory foam mattresses, namely falling in love with a Tempur. I knew I wanted a dedicated memory foam mattress only.
I believe the Ergoflex absolutely stands up to and holds it own against a Tempur - for a quarter of the price.
I am a 33 year old male, 6'1 and weigh ~85kg. I am a side sleeper and would describe this mattress as medium firm, which is exactly what I wanted.
The mattress is very high quality and delivery was fairly easy. Well packaged - your average mattress in a box. I'm pretty strong but you might want a second pair of hands for moving this mattress as being memory foam it's quite dense.
I absolutely look forward to getting into bed at the end of every day with my Ergoflex. It is so unbelievably comfortable and I could never go back now. I know what I'll be buying in the future should I need another mattress.
Save yourself the hassle and time, just pull the trigger on an Ergoflex - you won't regret it. The idea of returning it (on the 30 day policy) - never even crossed my mind.
