Need your order in a hurry? We can help. Some orders might be too big to ship on an airplane, and are delivered via semi-truck. However, smaller orders can be shipped Next Day Air and Two Day Air, depending on your zip code. eComfort offers expedited delivery on all eligible items that are in stock. Just look for “Next-Day Air Available” to see if the item is eligible for overnight delivery. Simply order before 4 p.m. EST (M-F), and your order can arrive as quickly as the next business day. Next Day Air orders submitted overnight and on holidays will ship the next business day. Only select items qualify. Any items that are shipped directly from the manufacturer do not qualify.
