EDX 10 Inch King Gel Memory Foam Mattress vs Mokiiya 12" King Hybrid Mattress

Buy the EDX if you want an all-foam king with a gel layer and a soft pillowtop feel and you sleep alone or mostly still. Buy the Mokiiya if you share the bed or want a medium-firm hybrid with pocket springs, which handles motion transfer and edge support better than foam alone. Both rate 4.2, but the EDX has far more ratings behind that score, so its record is more proven. The Mokiiya is the sturdier pick for couples; the EDX is the softer, simpler pick for solo sleepers.

  • Choose the EDX if you want a soft, conforming all-foam king and a gel layer aimed at sleeping cooler, and you do not need spring support.
  • Choose the Mokiiya if you share a bed and want a medium-firm hybrid with pocket springs that cut motion transfer and hold their edges.

Questions and answers

Which is better for couples?
The Mokiiya. Its individually encased pocket springs isolate movement, so a partner's turning is felt less, and its reinforced edges hold up better when two people share the surface.
Which is better for side sleepers?
The EDX suits side sleepers who want a softer, conforming surface that cushions shoulders and hips. The Mokiiya's medium-firm feel is a better fit for back and stomach sleepers.
Which lasts longer?
Both use CertiPUR-US certified foam, but the Mokiiya's reinforced edges and spring core are built to resist sagging over time. All-foam beds like the EDX tend to soften at the edges first.
Is the Mokiiya worth stepping up to over the EDX?
If you share a bed or sit on the edge often, yes. The hybrid's springs and edge support are the main upgrade. Solo sleepers who like a soft, sink-in feel can stay with the EDX.
Do either sleep hot?
Both claim cooling: the EDX through gel foam and a wave-pattern airflow layer, the Mokiiya through a breathable 3D-knit cover over an open spring core. Neither is a sure fix for hot sleepers.
How thick are they really?
The Mokiiya is 12 inches and expands to full height within 72 hours. The EDX is listed as 10 inches in one place and 12 in another, so confirm the height before you buy.
