OkiOki Mattress Review: Four-Model Hands-On Comparison Restored
OkiOki is now archived, but the original Yawnder review was unusually useful because we received all four firmness models and compared them side by side.
Four distinct models
The older lineup included OkiSoft, OkiEasy, OkiFlex and OkiFirm. The models used different combinations of memory foam, graphite foam and pocketed coils rather than simply changing one thin comfort layer.
Cooling covers
All four mattresses used a cool-to-the-touch cover material. That gave the lineup a consistent surface feel even though the support systems varied substantially from model to model.
OkiSoft testing
The OkiSoft used a simple all-foam build. Our 14-pound bowling-ball test showed the deepest sinkage of the group, and motion transfer was very low because the soft upper foam absorbed impact.
Why the comparison mattered
Having all four models in the same room made it possible to see a gradual progression in firmness rather than relying on brand labels alone. That hands-on comparison is worth preserving even though the brand is no longer active.
Current-shopping note
OkiOki is archived/closed, so this page is preserved as a historical multi-model review rather than a current shopping recommendation.
