Discover how a Simba purchase can refresh your bedtime setup with free pillows, duvet, protectors and a pair of slippers
The popular Simba mattress promotion is back for a short window, offering shoppers a chance to claim a sizable bundle of free sleep accessories when they buy selected mattresses. For the period that runs from 17 April to 27 April, customers can access a package valued at up to £836 and, by entering the code FREE-SLIPPERS at checkout, receive a bonus pair of reflexology-inspired slippers.
This is a limited-time opportunity that combines mattress purchase and immediate bedding upgrades, and the code and extras are only valid until 11:59pm on 27 April.
This offer is more than a token gift. Buyers who choose qualifying mattresses through the offer page can pick up complimentary items such as pillows, a duvet and mattress protectors, effectively replacing multiple elements of a bedroom set in one transaction.
The slippers included via the code are designed to aid foot comfort and fit into Simba’s broader focus on sleep and recovery. If you are evaluating an upgrade, this bundled approach cuts the cost of building a complete sleep setup and simplifies the shopping process.
What the bundle contains and why it matters
At the core of this promotion is a collection of free essentials that can total up to £836 in value depending on the mattress selected. Typical inclusions are multiple pillows, a temperature-appropriate duvet and protective mattress covers that guard against spills and wear. Using the code FREE-SLIPPERS adds a pair of reflexology-inspired slippers intended to help alleviate tired feet after a long day. Together, these extras mean that a single purchase can refresh the majority of what touches the body overnight, not just the mattress, which is a clear financial and practical benefit when compared to buying each item separately.
Technology behind the mattresses
Simba highlights cooling and support across its hybrid collection, and its Hybrid Pro model has been singled out for recognition as Product of the Year 2026. Key attributes include a cool-touch cover, layers of breathable wool and a top layer of graphite-infused foam designed to help regulate temperature. These features combine to address common overnight complaints such as overheating and uneven pressure distribution. The brand frames its construction as a purposeful response to warmer nights, with materials chosen to promote airflow and consistent comfort.
How the support system works
One of Simba’s engineering points is its patented Aerocoil microsprings, which form part of the mattress architecture. In simple terms, the microspring system is intended to enhance internal circulation of air and provide targeted responsiveness where the body needs it most. That layered approach also minimises movement transfer, reducing the disturbance one partner feels when the other shifts in bed. For sleepers who share a mattress, those technical elements—combined with the cooling surface materials—make the Hybrid Pro and similar hybrids attractive options.
Purchase protections and customer reassurance
Every mattress featured on the offer page carries extra shopper protections that aim to remove typical buying friction. Customers who purchase through the promotion receive a 200-night trial and a ten-year guarantee, giving time to assess comfort and long-term durability. Simba also provides free next-day delivery for eligible orders and an optional old mattress removal service to simplify the transition. These policies, alongside more than 350,000 five-star reviews and over 100 product awards, are meant to reassure buyers that the brand’s claims are backed by broad consumer feedback and industry recognition.
Why the bundled extras improve value
Bedding components add up quickly when purchased separately; combining them with a mattress sale reduces aggregate spend and saves the effort of sourcing compatible items. The free pillows, the duvet and the protectors included in this promotion represent an immediate addition to the mattress purchase that materially increases overall value. When paired with delivery conveniences and trial and warranty protections, the bundle becomes a compelling route for anyone ready to upgrade their sleep environment without hunting for multiple sales and coupon codes.
To take advantage of the offer, shoppers should act within the specified timeframe—17 April to 27 April—and remember to apply the code FREE-SLIPPERS if they want the reflexology-inspired footwear added to their order. The promotion closes at 11:59pm on 27 April, and the code will not work after that moment. For those considering a mattress change now, the combination of product technology, protective purchase terms and the bundled extras makes this Simba promotion worth reviewing before it expires.
