My Green Mattress Promo Codes & Coupons September 2025

If your My Green Mattress promo code isn’t working, it usually means the code is invalid, expired, or doesn’t apply to the items in your cart. Error messages like “code not valid” mean the code was entered incorrectly or isn’t recognized, “expired” means the code is no longer active, and “does not apply to items in your cart” means your selected products are excluded from the promotion.

Common scenarios include:

• Entering the code with typos or extra spaces
• Using a code past its listed expiration date
• Trying to apply a code to excluded items like clearance, bundles, or already discounted products
• Attempting to use a single-use code more than once

Step-by-step solution:

1. Double-check the code for accuracy and remove any spaces.
2. Confirm the code’s expiration date.
3. Review the terms to ensure your items qualify.
4. Try a different code if the one you have is not accepted.

Pro tip: Always copy and paste codes directly from a trusted source and check the promo’s details for product or category restrictions before checking out.

Yes, My Green Mattress promo codes often come with restrictions or exclusions. Codes may not apply to sale items, bundles, or specific products, and some codes are only valid for certain categories or minimum purchase amounts.

Typical restrictions include:

• Exclusions for clearance or already discounted items
• Codes that only work on select products (e.g., crib mattresses or accessories)
• Inability to combine codes with other promotions or offers
• Minimum order value requirements for some codes

Always review the terms listed with each code, as some are sitewide while others are product-specific.

Pro tip: Before shopping, scan the promo code’s fine print for exclusions—especially if you’re buying sale or bundle items.

You can tell by reading the details provided with each promo code—sitewide codes will say “storewide” or “all orders,” while category-specific codes mention the eligible products (like “$25 off Emily Organic Crib Mattress”). Single-use codes are usually sent via email or as part of a special offer and may state “one-time use only.”

Look for these clues:

• “Storewide” or “sitewide” in the code description means it applies to all products
• Product or category names in the code details indicate limited applicability (e.g., “$25 off select products”)
• Single-use codes are often personalized and may require you to log in or use a unique link

Pro tip: Always check the code’s description and any accompanying terms before applying it—this saves time and avoids checkout frustration.

No, My Green Mattress does not allow stacking multiple promo codes. You can only use one promo code per order, and most codes cannot be combined with other promotions, discounts, or offers—including sale prices or free shipping deals.

Key details:

• Only one code can be entered at checkout
• Codes cannot be combined with other offers or sitewide promotions
• Some codes may automatically apply the best available discount, making additional codes ineligible

Pro tip: Choose the promo code that gives you the highest savings for your order, and check if free shipping is already included or automatically applied.
