Simba Sleep is a British mattress brand that has quickly become one of the most recognized names in hybrid mattresses. Founded in 2015, the company combines the body-hugging comfort of foam with the responsive support of springs, developing mattresses for a variety of sleeping positions. Over the years, Simba Sleep has expanded its range to include several hybrid models, bedding accessories, and even sustainably refurbished models—all with a 200-night trial and a 10-year guarantee.
What sets Simba apart is its focus on layering advanced materials to maximize comfort and performance. Most models feature conical Aerocoil® springs for responsive support, open-cell Simbatex® foam for breathability, and a dense foam base for durability.
Simba Mattresses are vacuum-packed and delivered in a compact box, making them easy to maneuver through narrow stairwells or small apartments. After unpacking, the mattress expands almost immediately, reaching nearly its full size within a few hours. Initially, it has a slight “new mattress” smell, but this usually dissipates within 24–48 hours.
The cover feels soft, breathable, and of high quality. Unlike some cheaper mattresses, which can feel flat or lumpy upon first touch, the Simba’s surface feels plush and inviting.
One of Simba’s strongest selling points is its balance of softness and support.
• Hybrid Essential – This model is the most affordable in the range and offers a medium-firm feel suitable for most sleepers. The thinner profile still provides targeted support thanks to the Aerocoil® springs, but the edge support is slightly less robust than higher-end models.
• Hybrid Original – The brand’s bestseller. This model is more cushioned at the top, offering better pressure relief for side sleepers. Motion transfer is minimal, making it ideal for couples.
• Hybrid Pro – Designed for those who want luxurious comfort without sacrificing support. It features additional comfort layers that offer a softer sink-in feel while maintaining spinal alignment. Ideal for back and side sleepers.
• Hybrid 2500 & 4000 – These models feature a higher spring count, improving responsiveness and edge support. They are suitable for heavier sleepers or anyone who prefers a slightly springier sleeping experience.
A common complaint about foam mattresses is heat retention. Simba solves this problem with its Simbatex® foam – an open-cell structure that allows air to circulate more freely. Combined with the spring layer, which naturally promotes air circulation, Simba mattresses are significantly cooler to sleep on than all-foam mattresses. Even on warmer nights, most sleepers sleep comfortably without waking up overheated.
If you share a bed, motion isolation is especially important. Simba’s hybrid construction absorbs motion excellently. This means you won’t feel your partner’s every toss and turn—a huge plus for light sleepers or couples with different sleep patterns.
Edge support varies by model. The Hybrid Essential and Original offer decent, but not exceptional, edge support. Higher-end models like the Hybrid Pro and 4000 offer significantly better edge support, which is helpful if you sit on or sleep near the edge of the bed.
Simba’s mattresses are made from high-density foam and hardened steel springs, ensuring long-lasting comfort. Although some users report sagging after a few years, the 10-year warranty offers peace of mind. With proper care and regular rotation, the mattress should comfortably last 7–10 years for most sleepers.
• Side sleepers – Pressure relief in the upper layers ensures comfort for the shoulders and hips.
• Couples – Low motion transfer minimizes discomfort.
• People who sweat while sleeping – Breathable foams and a bouncy airflow keep body temperature low.
• People who want a balanced sleeping experience – Not too soft, not too firm, with adaptive support for different positions.
• Firmness Variations – Most people find Simba mattresses comfortable, but some sleepers find them too soft or too firm.
• Edge Support on Budget Models – If you need strong edge support, consider mid- to high-end models.
• Return Process – While the 200-night trial period is generous, some customers report that returns can take longer than expected.
While Simba isn’t the most affordable mattress on the market, it offers several models to suit every budget. The Hybrid Essential offers Simba comfort at a more affordable price, while the Hybrid Pro and Ultra appeal to those willing to invest in luxury. The brand also offers refurbished models for eco-conscious shoppers, saving hundreds while still offering high-quality comfort.
The majority of Simba customers praise the improved sleep quality, reduced back pain, and better temperature regulation. Many report waking up more rested within the first week of use. While there are some negative reviews—mainly regarding firmness preferences or delays in customer service—the overall sentiment is strongly positive.
For most sleepers, the answer is yes. Simba Mattresses combine the cushioning properties of foam with the support and breathability of springs, providing a comfortable and adaptable sleeping surface. They’re well-suited for couples, side sleepers, and anyone who struggles with overheating at night.
If you’re looking for a mattress that feels luxurious without being too soft, and you value features like cooling technology, motion isolation, and a risk-free trial period, Simba is a great choice. Just pay attention to your preferred firmness and choose the model that best fits your needs.
