The Sunny Health & Fitness Asuna is a slim folding motorized treadmill designed for walking and light jogging in compact home spaces. It is built for users who need a full-length running deck that stores flat under a bed, sofa, or raised surface when not in use. A 2.5 peak HP DC motor drives speeds from 0.6 to 8.0 MPH, and the unit folds to just 4.5 inches tall for storage.
After an evening walk session, the Asuna folds flat in seconds and slides under the bed — out of the way until tomorrow morning.
Why This Slim Folding Treadmill
Folds to 4.5" tall — the flat-fold design with transportation wheels stores under raised furniture, making it practical for apartments and small rooms without a dedicated fitness space.
49" × 17.5" running deck — full-length belt for comfortable walking and light jogging strides despite the slim profile.
Built-in MP3 speakers — connect via 3.5mm AUX cable; no Bluetooth pairing required.
Shock absorption system — integrated cushioning in the running deck reduces surface impact during use.
5-year frame warranty — structural frame covered for 5 years; mechanical parts and electronics covered for 180 days.
