The point of the latex topper was to save the mattress from wearing prematurely....to keep it from developing body impressions.
Had you used it, the mattress would still be in like new condition.
A Simmons Black model won't hold up any better, as it's the memory and poly foam upholstery that creates the impressions and sags.
We continually search for high quality alternatives to what the name brands are producing.
We have a brand from Canada, called Natura.
The Natura Greenspring Liberty Ultra Plush uses a pocketed coil that is made the same as Simmons, (Barrel shaped and pre-compressed), but better, (Double tempered coils and a higher coil count).
More importantly, this mattress is upholstered with natural Talalay Latex, and contains no memory foam.
My wife and I are sleeping on this mattress. It isn't overly soft, but it is comfortable. It provides excellent support. We sleep well, wake rested, and have no pain...despite her sore hip and my bad back.
This would be my recommendation to you.
