Apply the coupon code (step by step)
- Choose the CoolNest memory foam or the hybrid on sweetnight.com, the build differs more than the price does.
- Add pillows or a frame in the same order to trigger the two item or three item saving.
- Open the cart and enter the coupon code in the discount field.
- Apply it and check whether it stacked with the bundle percentage or replaced it.
- Place the order, then note the delivery date, the 100 night trial counts from there.
- Sleep on it for at least 30 nights before deciding, that is what the trial asks.
Mattresses priced for the discount, not the list
SweetNight sells mattresses, bed frames, pillows and bedding direct, and the list prices are not where anyone actually buys: the CoolNest memory foam mattress carries an MSRP around $659.99 for a king while the regular selling price sits nearer $449.99, and a queen commonly lands at $399.99 against a $669.99 list. The CoolNest range spans roughly $389 to $699 depending on size and whether you take the memory foam or the hybrid. The 12 inch CoolNest is built from six foam layers, fiberglass free and CertiPUR-US certified.
Trial, warranty and the price match
Every mattress comes with a 100 night sleep trial, and SweetNight asks that you sleep on it for at least 30 nights before starting a return, which is standard practice for foam that needs breaking in. The warranty runs 10 years, shipping and returns are free, and a 30 day price match guarantee sits behind the order in case the same mattress drops after you buy. Bedding to go on top is worth comparing with Bedsure, and Instamattress is the alternative if you want a different build entirely.
Standing ways to save
The multi item tiers are permanent rather than seasonal: buy any two products and save 10%, buy any three and save 15%, which is why a mattress plus pillows order beats buying the pillows later. Sitewide sale events reach up to 45% off, and a coupon code generally applies against the already reduced price rather than the MSRP. Since the price match runs 30 days, ordering ahead of an announced sale is less risky here than at most mattress retailers.
