Overview
Sized specifically for Twin XL beds, Viscosoft's 3 inch topper uses gel-infused memory foam over a slip-resistant, strap-secured base meant to stay in place through regular dorm-room use.
The gel infusion is aimed at pulling heat away from the body, addressing the way standard memory foam can trap warmth overnight. A slip-resistant bottom paired with adjustable elastic straps is built for a bed that gets moved around and re-made often, rather than a mattress that stays untouched for months. The cover comes pre-fitted and is removable for machine washing, and Viscosoft markets the whole set toward the frequent motion of college dorm life.
- 3 inch gel-infused memory foam
- Sized for Twin XL beds
- Slip-resistant bottom, adjustable straps
- Removable, machine-washable cover
Who it's for
This suits a Twin XL mattress owner, often a dorm resident, who wants a 3 inch memory foam layer that won't slide around and can be washed via its cover. It is not sized for a standard Twin, Full or Queen mattress.
Pros and cons
- Gel-infused foam for a cooler sleep surface
- Slip-resistant bottom with adjustable straps
- Removable, machine-washable cover
- Cut specifically for Twin XL, no other sizes
- Won't fix a badly worn mattress underneath
Performance notes
Gel-infused foam is meant to conduct heat away from the body faster than plain memory foam, which is the usual complaint with thicker foam layers. The slip-resistant bottom and adjustable straps work together to keep 3 inches of foam from creeping out from under a fitted sheet during normal use.
