They started with a single piece of thread, but now Simba Sleep manufactures high-tech affordable mattresses that adapt to your body for exceptional support. If you would like to try one, read the following guide to learn where to find and how to apply a promotional code, how to save without and some other tricks you can use to maximise your savings.
Discount programmes and eligibility promo codes
Your purchase at Simba Sleep doesn't have to be expensive. Check out our Discoup page to be in the known of any codes and promotions launched on the website and be ready to seize the chance or subscribe to the newsletter to trigger all of this and even a special discount valid on your first purchase. The official Simba Sleep channels, such as Facebook, Instagram, YouTube and LinkedIn, can also help you keep up with everything that the brand offers. Subscribe and you won’t regret it.
Simba Sleep even offers an eligibility route where users verify their status and then receive a code to use at checkout. The verification is designed to be quick and the voucher appears after eligibility checks. It is the case for students and NHS members, who can access via Health Service Discounts or Blue Light Card.
The referral programme is powered by Mention Me. At checkout you will in fact see appear a section called “Referred by Mention Me?”. Click here to enter the code you have obtained from a referral.
How to apply a Simba Sleep coupon code
Have you just found a Simba Sleep voucher but you don’t know how to use it? Don’t worry, we are here to help. The first thing to do is of course choosing the items you want to purchase, add them to your cart and then click on “Checkout” in the pop-up menu on your right once you are ready to finalise your order.
On the right, find the “Discount code or gift card” section under the itemized list of what you are about to buy. Enter here your promotional code and then apply. To avoid any mistake, copy/paste the code exactly as it is rather than typing it manually and watch for auto-capitalisation.
Before entering your contact, delivery and payment information, make sure that the discount has been correctly applied and the total due has been updated.
Why a Simba Sleep voucher code isn’t working
In this paragraph we will provide you with a list of common problems and easy fixes for a voucher code whose discount doesn’t apply at checkout. Read carefully the code terms and conditions to know:
- Its expiration date: if it has passed, try another promo code;
- If there is a region mismatch: confirm you are on the correct Simba Sleep site/region for the coupon you have;
- If discounts can be stackable: if there is another active promotion, it may be possible that you cannot use both. In this case, go for the best deal;
- Its limitations (e.g.: code reserved to new members, members, single-use only, etc.): make sure you fall within the required categories. If not, try again with another coupon with no limitations;
- Its restrictions (e.g.: already discounted items, bundles, refurbished products, etc.): test your promotional code with a single full-price item and then choose the best offer;
- If a minimum spend is required: sometimes a voucher works only if a certain threshold has been met. Check the basket value and add items to reach this criterion.
In case of tech issues, switch the browser you are using, try the private mode, clear the cached checkout and re-paste code.
Where to find additional savings
Beyond discount codes, there are other ways to get your cart reduced at Simba Sleep. One way is for instance to check the website for seasonal and temporary promotions. Usually, you can find them in the homepage or in separate dedicated sections. Discounts are often automatic and directly apply to checkout. The best periods for the greatest deals are Black Friday, Cyber Monday, Sales, etc.
If they are available, prefer to buy bundles, where the price of two or more items sold together is lower than the price of the single items. If you are in the lookout for great deals, you can always use the “Compare” section on the website.
Last but not least, you can enjoy free shipping on every order, the 100-night trial period to make sure you sleep well on your new mattress and the 10-year warranty: they are not a direct way to save but of course they can make your experience here at Simba Sleep even better.
