The Simba Hybrid Pro has seven layers, up to 5,000 springs (original up to 2,500 springs), an additional natural wool top layer and the softest sleep surface ever. The seven layers are:

  • Super soft, breathable sleep surface
  • Natural British wool layer
  • Open-cell foam layer
  • Two layers of patented spring comfort layers
  • High definition foam with edge support
  • Zoned support base.

Four layer, customisable hybrid construction:

  • 4cm foam
  • 5 customisable comfort zones with 4 different densities of deep foam
  • 10cm individual pocket springs (coil count: 1,000)
  • The springs are encapsulated in a high density, supportive foam that makes up the base and the mattress walls. They're then covered in a medium density reflex foam that ensures you feel the bounce of the springs below.

Note: This brand has changed hands so many times, it's hard know the current quality of the mattress.

Firmness info

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.

FAQs

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.
