Is the Arctus topper actually cooling?

The gel infusion and egg-crate surface help move heat and air compared with plain memory foam. It is not actively cooled, and hot sleepers may still find foam warm.

Will it make a firm mattress softer?

Yes. Three inches of memory foam add noticeable cushioning and contour to shoulders and hips, which suits side and back sleepers on a hard bed.

Does it fit a Twin-XL bed?

It is made for Twin-XL, the longer single size used in dorms and adjustable beds. Check your mattress dimensions before ordering.

Can I put it under a mattress protector?

Yes, a protector keeps it clean, but a thick one can mute the cooling and the egg-crate feel.

How long does it last?

Foam toppers typically last one to three years. Some owners report flattening sooner, so rotate it regularly.

Our take on the Arctus 3" Twin-XL Gel Cooling Memory Foam Mattress Topper

The Arctus is a 3-inch gel-infused memory foam topper in Twin-XL, with an egg-crate surface cut into the foam. The gel is meant to pull heat away and the egg-crate profile adds airflow and softness over a firm or worn mattress. It suits renters, dorm beds and anyone who wants more cushioning without buying a new mattress. Against flat 2-inch toppers it offers more depth and contouring, but it is still foam: hot sleepers and heavy bodies may find it warmer and softer than a latex or hybrid topper.
