Frequently asked questions
Can I use a half-bed topper on any mattress type?
Yes, most half-bed toppers work on innerspring, memory foam, and hybrid mattresses. Ensure the topper is the correct size for your mattress half, and check that it doesn't shift by using a fitted sheet.
How do I clean a half-bed topper?
Many toppers have removable, machine-washable covers. For the foam core, spot clean with mild detergent and air dry. Avoid soaking the foam, as it can retain moisture and cause mold.
What certifications should I look for in a half-bed topper?
Key certifications include CertiPUR-US for foam safety and durability, and OEKO-TEX Standard 100 for low chemical emissions. Organic toppers may also have GOTS or GOLS certification.
Can I cut a full topper to fit half a bed?
Some toppers can be trimmed to size, but it's best to buy a half-bed specific topper to avoid uneven edges. Check the manufacturer's guidelines before cutting, as it may void the warranty.
Does a half-bed topper help with motion transfer?
Yes, especially if the topper is made of memory foam or has a supportive layer. Half-bed toppers that are individually designed for each side can reduce motion transfer more effectively than cutting a full topper.

For most couples, the Sleep Number True Temp Topper is the overall winner for its dual-zone cooling and customizable comfort.
