Our materials come from nature - whether it be wool sustainably sheared from New Zealand sheep or latex tapped from trees. These premium materials are comfortable on your body and conscience. 100% all natural & organic Birch Wool provides unparalleled comfort and temperature regulation. Birch Wool is designed to retain shape with a natural elasticity of each fiber. Talalay latex is up to 7 times more breathable than other types of latex. Natural latex is also hypoallergenic and anti-microbial.
Support	Combining the most innovative titanium infused foam on the planet and the support of high quality individual coils with extra edge support, The Alexander Hybrid Signature Series is the most comfortable mattress on the internet. The Alexander Signature Hybrid Mattress utilizes a very durable individually pocketed coil unit with edge support coils all around the perimeter. This provides a movement-free sleep surface and supports the back perfectly.	We spent countless hours finding the right density of latex, quantity of wool, and type of steel springs to provide unprecedented comfort and pressure relief. Each mattress features a reinforced perimeter for best in class edge support. The coils that run along the outside of your mattress are actually firmer, so no more feeling of falling off the bed when lying down or sitting on the edge. Natural Talalay latex provides response to cushion your pressure points while giving support. Our latex is carefully managed to ensure consistency. Hundreds of individual steel coils help to cradle your body and provide support, while also limiting motion transfer. Additionally, the reinforced perimeter coils provide best in class edge support.

Is the Sparrow mattress suitable for intimate activities?

The Sparrow mattress is ideal for couples due to its various features. It has increased edge support coils, handles for adjusting, and responsive foams that provide a supportive surface for both sleep and intimate activities.

How is the Sparrow mattress shipped and how long does it take to expand?

The Sparrow mattress is compressed, folded, and rolled into a large cardboard box for shipping. Once received, it will reach its intended height within 12 to 24 hours, although it might take up to 72 hours to fully expand.
