The Simba Hybrid Pro is medium-firm in feel, however, because of the dual spring layers and wool layer the Pro provides a slightly softer, plusher, more luxurious feel than the Hybrid. 95% of Simba sleepers love their mattress. If it doesn't work for you, Simba mattresses that are returned are either refurbished or recycled; they never go near a landfill site.

CoverThe zip at the half way mark on the mattress allows for easy removal and wash of the top part of the cover, giving you a fresh sleep, night after night.

The mattress has four convenient handles to allow you to rotate or move your mattress with ease. Whilst the cover itself is not removable or washable, the grey base fabric can be cleaned with a soft, damp and clean cloth using small circular motions.

Machine-washable coverNoYes
Ergonomic handlesNoYes
ComfortThe top AirTech® Comfort foam layer increases the cosiness of the mattress, giving the sleeper a great sleep, night after night. Manufactured in the UK, AirTech® foam is the very latest in memory foam technology, and is 30 times more breathable than some leading foam brands. This, and the memory foam's unique open cell technology, helps to promote air circulation, keeping your mattress fresh and keeps you cool and comfortable throughout the night.Added springs and layers provide a plusher, more luxurious feel, even better heat regulation and ultimately an even more comfy night's sleep. Meaning there's now a Simba for a wider range of needs and budgets. An even thicker knitted cover increases the comfort without compromising airflow. Wool is naturally temperature regulating and moisture wicking and a dream for hot sleepers. Whatever the season you can rest cool and rest easy. Open cell Simbatex foam is infused with graphite for enhanced cooling. The conical design of the springs means they are cone-shaped and allow for greater airflow between the springs.
SupportThe OTTY Flex utilises our own AirTech® foam - an open cell foam which offers a perfect blend of comfort, breathability and support. The AirTech® Support layer helps to provide a great level of support. This helps to ensure the sleeper wakes up pain and niggle free. The pressure-relieving profiled base has three specially-designed zoning areas, which helps to improve comfortability.More miQro® springs mean greater airflow and better body weight distribution. Plush, lush, gravity-defying comfort. Up to 2,500 additional miQro® springs mean greater airflow and better body weight distribution. These 25mm conical pocket miQro springs are made with 100% British steel, manufactured in Leeds and are enclosed in a 100% polyester pocket. High definition foam with edge support means you won't get that feeling of rolling or falling off the bed when sleeping or sitting on the border. A zoned support base provides different levels of support to different areas of your body to reduce pressure points.

Simba Hybrid Pro

Is the Simba hybrid Pro best for heavy people?

The Simba Hybrid Pro is considered the best overall hybrid mattress for heavy people according to a 2023 ranking. Simba does specify weight limits for its mattresses, with the 10-year warranty covering a maximum weight of 114kg per sleeper for all of its adult hybrid mattresses. Thus, for individuals within this weight range, the Simba Hybrid Pro offers ample support and comfort, making it an excellent choice.

Is the Simba Hybrid Pro worth the extra money?

While the Simba Hybrid Pro is indeed among the more expensive bed-in-a-box options in the UK, its high quality and unique features can justify the cost for many customers. Compared to other premium mattresses like the DreamCloud Luxury Hybrid, it may cost more, but the superior comfort, support, and advanced technology found in the Simba Hybrid Pro make it a worthwhile investment for those seeking a premium sleep experience.

How thick is Simba Hybrid Pro?

The Simba Hybrid Pro is 280mm thick, making it 30mm thicker than the regular Simba Hybrid mattress. This extra thickness comes from two additional layers in its construction. Despite its greater thickness, most standard fitted sheets should still accommodate the Simba Hybrid Pro mattress comfortably.
