What sizes does the Smart Cover come in?
Three, matching standard mattress sizes:
Queen, 60″ W × 80″ L
King, 76″ W × 80″ L
California King, 72″ W × 84″ L
Choose the size that matches your mattress. Using a size that does not match affects both fit and performance.
Orion is not currently available in Full or Twin.
How thick a mattress does it fit?
Up to 18 inches.
The Smart Cover uses an extra long fitted design that wraps securely around thicker mattresses and keeps the cover positioned properly through the night.
Where does the Smart Cover sit?
Directly on your mattress, underneath your fitted sheet. It also works on top of a mattress topper.
Does it work with my bed frame?
Yes for standard slatted and platform frames, and for most adjustable bases.
On an adjustable base, use a standard mattress rather than a split king, and keep the mattress within 2 inches of flat while Orion is running overnight.
See Will Orion Work With My Bed Setup? for the full answer.
Does it replace my mattress?
No. Orion goes over the mattress you already have.
Contact Orion Support with your mattress size, depth, and base type and we will confirm the right fit.
