update on my Simba mattress'
1st replaced faulty - collapsed on the edges
2nd replaced faulty - a dip formed half way down the bed in a straight line causing hips to sink in the bed
3rd few months in and can already feel indentations, a definite high spot in the middle of the mattress.
wouldn't recommend one to anyone, unless you weight the same as a bag of sugar. I'm not a small person but I'm by no means a lump of lard. 100kg which is under that recommendation by them.
I've never known a mattress to sink as quick as these do.
going to wait this one out, if it gets bad then will just bite the bullet and get a different mattress.
