Edge support could be better.
"I'm a 277lb dude and I had an old hybrid mattress for about 7 years, aged, and gained weight in that time and developed discomfort overnight. I figured a new mattress would alleviate some of the stress in my body at night and it slightly did. This mattress has a consistent firmness throughout and doesnt sink in in the middle, but the edge does flatten too mush for me to notice any extra supported edge support that the advertisement shows.. I dont feel any edge support, overall it wasnt a big change in my sleep and next time around I'll try another brand, this mattress isn't spectacular enough to come back too."
