While we are able to make the exact or nearly-exact same mattress models in our previous line today, certain kinds of foam are no longer available due to the advancing of mattress technology, and may need to be substituted for their same or higher quality equivalents. Rest assured, any substitutions neccessary are minor and will not affect the feel or firmness of the mattress. We have made these mattresses available by phone order only in order to give our returning customers special pricing on these models, as the cost of foams has risen significantly over the years, we are offering lower than normal prices on these mattress configurations in order to do right by our returning customers. Call (800) 667-1969 to get a quote on one of our previous Tempflow models.
