Mattress firmness: Medium Firm. The SUPA Latex Mattress uses natural latex (made in Thailand) for its breathability and resiliency.  Features: Made of three layers: exchangeable/ washable soft white velvet top layer + meshed middle layer + natural latex layer as the core can be used on either side  The covering layer where most skin contacts occur is made of Velvet. Its low density makes it light and comfortable while also giving it a luxurious feel. The middle layer (or transition layer) is made of Single Jersey. The material is very efficient in heat and moisture transport and air permeability. That is why the mattress would be warm in winter but also very breathable and excellent at preventing sweat during hot days. Finally, the core layer is natural Latex. The gentle cushioning and buoyant support of latex foam are especially beneficial for spinal alignment and great at preventing back and joint pains.

Additional information: All of our mattresses can be used immediately, but remember that a packaged mattress only regains its full shape and comfort after approximately 72 hours. Your body also needs a couple of weeks to adapt to the new mattress. Sometimes the mattress has a noticeable smell when you open the packaging. The smell isn’t harmful or toxic and disappears over time. Airing and vacuuming the mattress helps to eliminate the smell faster.
