Hi chs4000,
They certainly are a reliable and conscientious company. Return policies are generally built into the cost of a product so that the people who don’t return a product are paying for the ones that do.
It’s certainly a high quality product at a good price although I would add a cover to protect the topper from long term oxidation. If you are looking for something softer in a 2" topper then KTT Enterprises has the full range of Latex International Talalay in any thickness and ILD.
Any latex will be a more durable choice than other types of foam toppers but in the lowest ILD’s then 100% natural Talalay can be less durable than blended Talalay from Latex International although Radium says that in the case of the Talalay they manufacture both would be roughly the same in terms of durability.
There are too many unknowns, variables, and preferences involved in either mattresses or toppers to make specific suggestions but the topper guidelines I linked earlier have some general suggestions in terms of thickness and ILD that use your sleeping experience and how much more softness and pressure relief you are looking for as a reference point.
