The Arctus is a 14-inch full-size memory foam mattress in a box, built with a gel-infused foam layer and a removable, fiberglass-free cover. It is a plush mattress: soft on top, with high-density foam underneath to limit sink and motion transfer between sleepers. It suits side sleepers and couples who want a cloud-like feel rather than a firm bed. Against rivals, the removable cover and fiberglass-free build are the standouts; the plush feel is the main trade-off for back and stomach sleepers who need more pushback.

Ratings are good but not glowing, averaging about 4.1 out of 5. Buyers tend to like the soft, contouring feel and the cover; the most common reservation is that plush is genuinely soft, which some find too yielding.
The Arctus Full Size mattress is a 14-inch gel-infused memory foam mattress with a plush feel.
The memory foam conforms to the neck, shoulders and hips to relieve pressure. The high-density foam minimizes motion transfer, so movement on one side of the bed is less likely to disturb a partner. The breathable foam reduces heat buildup.
The plush feel is soft but supportive, and the mattress cushions the body without bottoming out. It suits side sleepers, light sleepers and couples.
