At Sleep Number, you can save as much as $1,600 when you bundle a mattress with an adjustable base, mattress pads, pillows, and other bedding items. The discounts will apply automatically in cart. Plus, you’ll get free Premium Delivery on your order right now. A 100-night trial covers the mattress itself, though adjustable bases are typically excluded and are non-returnable, so it’s worth checking which pieces of a bundle are covered before buying.
