Tempurpedic Luxeadapt or Naturepedic EOS Pillowtop?

They are both different classes of mattresses but im having a hard time decide which to jump for.

Looking at a tempurpedic luxeadapt 2.0 hybrid medium (plus a topper to make it a bit more soft cloud like feeling)

or a naturepedic EOS pillowtop ultra plus organic mattress: https://www.naturepedic.ca/eos-pillowtop-organic-mattress-buy?466=1093

i like the concept of the natrepedic, and 100 day gurantee or they take it back.tempur im stuck on a exchange only wherever i go. im jsut not sure if it would last as long as the tempur since naturepedic you "assemble" the mattress

any recomendations?
