The Bottom LineBoth mattresses are quite similar in construction. Silk and Snow is a bit cooler than Novosbed and is an excellent choice for combination sleepers. Novosbed lets you choose the firmness of your choice and provides an additional foam layer for further fine tuning. If you are a heavier person, Novosbed is a better of the two. Both mattresses provide you a peaceful, pressure-relieving rest. Price and cost-based value of both products is also comparable.
