I want to buy from Costco due to their great return policy, so I'm limited in my choices.  I have tried memory foam and hate it, so not an option.  Also 6'1" 280lbs, so looking for something firm I won't sink all the way into.

My current choices from the Costco lineup are three Sealy innersprings and a latex "hybrid".

* Sealy Alanson Cushion Firm - $580

* Ivory Forest Firm - $650

These two look to be the same construction with some variation in the types of foam used in the comfort layer. 

*Springport Firm - $680 (on sale from normal $800)

This one looks to have the upgraded "XT" edge support and some extra foam, including a .79" latex layer

Sleep Science Latex 10" - $990

Latex looks interesting and my research makes me think it will have a longer life than an innerspring.  It is at the top of my budget so I would probably drop in on my existing box spring which seems to be in good shape.  I can add a board if necessary. 

If I go with an innerspring, I'm thinking less foam is better since that is what seems to degrade.  I can always throw on a topper if too firm. 

So, do I go cheap and plan on throwing it away in five years, go for the mid-point with the Springport on sale, or splurge on the latex and hope to get more life out of it.

Thanks for any advice.
