Which is better for overnight guests?

The Inofia, mainly for its removable washable cover and non-slip base. The Dyonery is fine if you just want the lower price.

The Inofia uses gel-infused foam, which is designed to pull heat away. The Dyonery claims heat dissipation up to 3x faster than standard foam but uses no gel.

The Dyonery states a medium 6-7/10 firmness. Inofia does not publish a firmness number, so its feel is less predictable.

Is the Inofia worth the extra money?

Yes if you want the washable cover, gel foam and non-slip base. If you only need a cheap spare bed, the Dyonery saves money.

The Dyonery backs its mattress with a 10-year limited warranty. Inofia does not state a warranty, so the Dyonery is the safer bet on paper.

Can either be used in an RV or camper?

Yes. Both fold into thirds, and Inofia lists RV, camping and dorm use, including a Short Queen size for bunks.
