The Sonno Gel Versa Mattress (2014) caters to couples by comprising two individual reversible mattress halves placed side by side snugly inside its cover. Each half of the mattress has a gel side and foam side, allowing you and your partner to each choose the firmness that suits your individual needs. (The seam between mattress halves is undetectable.) The gel side is the softer choice and it caters to those who prefer a mattress with more give. While providing optimal support and comfort, the gel side has a special aerated foam layer that cradles your body and dissipates excess heat. The mind foam side provides firmer support with less give. Both sides quickly adjust to your position without requiring a warm-up period, supporting your weight whenever you roll. This results in a feeling of floating, allowing you to rest naturally, isolated from pesky vibrations and movements that interrupt sound sleep. Free of metal coils that loosen and shorten the life of traditional mattresses, Sonno is designed to last. It ships rolled in a compact tube for easy handling and rapidly expands to full thickness when unpacked, ready for use on any well-ventilated platform or slat bed. Backed by a 10-year warranty. Made in Italy.
