we own a crib mattress, a twin box spring and two queen sized latex mattresses all from vivitique. superb mattresses... comfortable to the extreme, durable (over two home moves), kids and dog/cats, and attractive. we could not be more pleased...

crib mattres was about 350
twin was about 600
queens were 400 and 1400 (one was a factory second we got as a bonus because they made it too soft to our specifications... so they sold it to us for below cost instead of tossing it away.)

in addition to the fresh and clean feel of the mattress and the fact tht they are the most comfortable mattresses we have ever owned, the simple fact that we put our heads down on them with the confidence that we (and our young kids) are not inhaling brominated flame retardants, formaldehydes etc... allows us to sleep that much more soundly.
