Query: very comfortable

Pros:--Smooths out a rough sofabed perfectly.--Nice materials and construction all around.--Sylvane's price of $788 is $hundreds cheaper than just about everywhere else.--Cover is not satiny smooth, so it won't slip around.Cons:--Heavy to handle, if it has to be stowed every day, like mine does. On the other hand, the weight is a plus as regards sturdiness and protection.--Expensive. Maybe it's worth it, since it so much better than anything else I've seen. I don't need the hypoallergenic features.Although this relates to the vendor rather than the product, Sylvane did a nice, fast job getting it here.
