Hi drog.
Welcome back and congratulations on your weight loss! … 75 pounds is quite a feat. :lol:
Losing that much weight would certainly make a substantial difference in how firm a mattress feels… in general, a mattress would feel firmer for lighter people than the same mattress would feel for those who are in higher weight and losing even more weight will further change your needs and preferences quite significantly. The good news is that your mattress (From Arizona Premium) can accommodate this changes fine tunning what you have rather you having to replace the entire mattress. I’d say that the most cost-effective way would be to add a softer topper to your existing mattress for some extra softness and pressure relief and when the time comes you can move to stage two and exchange the top layer within your mattress for a softer ILD.
There is more information about choosing a topper in post #2 here and the topper guidelines it links to which along with a conversation with a reliable and knowledgeable supplier. Because of the uncertainty involved with purchasing a topper where you can’t test the combination in person … a good exchange/return policy can also reduce the risk of an online topper purchase so I would also make sure you are comfortable with the options you have available after a purchase to exchange or return the topper and any costs involved just in case a topper you choose also doesn’t turn out as well as you hoped for.
The topper and component reference post here includes the better online sources I’m aware of for latex toppers and components. You may wish to comb through some of our Trusted Members of the site who offer latex toppers and allow for topper exchanges. I don’t keep track of such specific details, as these policies are always changing, but at least it’s a bit of a start for you. Most businesses don’t offer a “comfort exchange” on toppers, as the feel of the topper is greatly influenced by the surface upon which it is placed, and a retailer has no control over this.
