| Bench Built - hand made quality assures uniformity and quality control on each futon. Box Edges - for a TRUE reading of thickness, 8" or 6" Overstuffed - generous amounts (approx. 14") of different combinations of highly resilient foam and fiber that create an "inside out" force against the mattress ticking that is necessary for proper and comfortable support, whether sitting or sleeping. Tape Edge Closure - expert mattress tailoring operation that seals the comfort inside the mattress, insures proper placement of materials in the cover and reinforces the edges to present a clean tailored look instead of a "haphazardly stuffed look." Compression Lace Tufting - This customized process alone will differentiate an Otis futon from any other! CLT serves to compress, strengthen and control the overstuffed cushioning materials. Our "button-less" tufting process forces the foam, fibers, springs an mattress fabric to work together to create a supportive synergy that produces a comfort level unique to each mattress… bottom line, your mattress will feel as supportive as it did on the first day. IMPORTANT TO KNOW WHEN TALKING ABOUT THICKNESS.. Thickness can be a relative term in the mattress industry! Normally, when someone says this mattress is 8"...it is 8"thick, or if they say it's 10"…you expect to see a ten-inch mattress, not some rounded mattress that is guessed to be about 10" thick basically for marketing purposes only! The only true way to decipher the actual thickness of the mattress is to have a measurable border material (or a boxed edge, like a traditional mattress does). All of our futon mattresses are bench built and are made with a boxed corner and are tape-edged…this is just part of our signature manufacturing process. The bonus is that the "thickness" of the futon is easily deciphered, and it leaves the mattress with a clean tailored look for many years. More important than the quoted thickness of the mattress, is the quality of the inside ingredients of the mattress. We carry two six-inch thick futon mattresses (Stratosphere and Nova) that are a better value and outperform some of the so-called 8, 9 and 10-inch futons in the market today! All of our futons are reputed to be of "premium quality, or high-tech" that keep their shape for 10-15 years; this is due in part to the quality of the key ingredient in our futon mattresses, which is FOAM. We only use highly resilient (H.D.) foam with densities that are 1.8 pounds per cubic foot or better. Some manufacturers use foam with densities of 1.4 or even worse, 1.2 (this will make a futon have a shortened lifespan, and even worse…damage the image of a futon). DON'T BE FOOLED BY THICKNESS…MAKE SURE YOU PURCHASE A GOOD QUALITY MATTRESS, AFTERALL, IT IS THE MOST IMPORTANT AND MOST USED PART OF THE FUTON SOFA SLEEPER! FUTON COVERS Standard futon covers were made to fit futons that are 6 inches thick. Standard covers fit our 6-inch thick futons ONLY! Some futon mattresses made with cotton, or cotton and foam, or even innersprings that claim to be 8 or 9" inches thick will still fit inside these standard covers due to the above reasons, but not ours! Our true 8"thick futon mattresses need a true 8" thick cover. If you try to squeeze our futons into a smaller cover it will alter the feel of the futon and make it even harder to bend into the frame. We recommend an 8" box cornered cover! |
