Right now, Diamond Mattress is running its Fall Sale, and the lead offer is a bundle deal that gives you free pillows when you purchase a mattress. This is an excellent option for anyone buying a new mattress who also needs comfortable pillows to complete their sleep setup.
To find the best savings, consider what you are planning to buy:
If you are buying any mattress: Start with the Fall Sale - Free Pillows With Mattress Purchase offer. This automatically adds free pillows to your cart when you select a mattress, making it a simple way to get more for your money without needing a promo code.
For a specific mattress like the Tailor Classic: Choose the Fall Sale - 50% Off Tailor Classic Mattress. This offer provides a big 50% discount on that particular mattress, with the price automatically adjusted on the product page. This is one of the biggest savings available.
For the Flurry Lux Cooling Hybrid mattress: You will get the most direct saving from the 44% Off Flurry Lux Cooling Hybrid deal. For example, on a $2,100 Flurry Lux mattress, the 44% discount would save you $924, making your final price $1,176. While the Fall Sale also offers up to $900 off selected mattresses, including the Flurry Lux, the 44% off deal is a clear, bigger saving for that model.
When purchasing the Black Diamond Mattress: The $600 Off Black Diamond Mattress + Free 2 Pillow deal is a strong choice, giving you a significant discount and two free pillows. Another Fall Sale offer gives up to $900 off selected mattresses, including the Black Diamond. If the actual discount on the Black Diamond mattress from the Fall Sale reaches $900, it would be a bigger saving on the mattress itself, so check the price for your specific model. Consider if the extra mattress discount from the Fall Sale is more valuable to you than the $600 off plus the free pillows bundle.
If you want the Dreamstage mattress: Look for the Dreamstage For $1,499 offer. This sets the final price for the Dreamstage mattress at $1,499. The Fall Sale also includes up to $900 off Dreamstage Value mattresses, so compare the marked price of the $1,499 Dreamstage mattress with any price shown for Dreamstage Value products under the Fall Sale to see which gives you the lower total.
For other items like a mattress foundation or an adjustable bed base kit: If you are buying a versatile mattress foundation, the 5% Off Versatile Mattress Foundation deal will give you a small saving. If you are looking for an adjustable bed base, check the Adjustable Bed Base Kits From $699 offer, which highlights models starting at that price.
If you are shopping the Labor Day Sale selection: The Labor Day Sale - $1000 Off Selected Products provides a large fixed discount on a range of items. This saving is already reflected in the product prices, so no code is required.
If you are a new customer buying a bed and base: Sign up for the Diamond Mattress newsletter. The Sign Up To The Newsletter & Get $100 Off Bed + Base offer will give you a promo code for a $100 discount on your combined purchase.
Diamond Mattress has offered 105 deals on our page in the 12 months to October 2026, with the biggest percentage sale reaching up to 60% off in August 2026. September 2026 and June 2026 saw more new offers than usual. Our team has no recorded checks for this brand in the past year.
