Hi saimantri,
Welcome to the Mattress Forum!
I’m guessing what you meant is that after all of your research you found that the latex hybrid is the best option for you. The Avocado Green Mattress uses 2" of 75 kg/m3 (plush) Dunlop and 1" of 95 kg/M3 (firm) Dunlop. The pillowtop version adds 2" of 85 kg/M3 (medium) Dunlop. It is 100% NR latex. It uses a pocketed innerspring unit. The Nest Bedding Alexander Signature Hybrid is a different hybrid, using polyfoam and memory foam on top of a pocketed spring unit, and varies with either a Medium or Luxury Firm configuration. Nest Bedding is a site member here, which means that I think highly of them, and the Avocado mattress uses good quality materials.
[EDIT: I forgot and left out the Nest Bedding Hybrid Latex when I originally replied to this post, which does use latex on top of a pocketed spring unit]
If you’re looking for other hybrid options pocketed springs using latex on top), while certainly not complete, you may wish to look at the companies listed in the hybrid thread in post #2 here.
I’m sorry, but I don’t keep track of which mattress manufacturers or retailers offer financing, so I can’t be of much help there. While the ability to finance may be an important part of your personal value equation, I don’t generally recommend using that as guidance to select a mattress, and instead would recommend following the steps outlined in the mattress shopping tutorial.
