- Firmer than some expected
Questions and answers
- Which is better for a child's first bed?
- The Novilla. It costs less at $73.99 and comes in Twin, so it fits a standard kid's bed frame. The 6-inch height keeps it low.
- Is the Kow worth the extra $16?
- Only if you want the Eurotop cover or plan to use an adjustable base. Otherwise the Novilla does the same job for less.
- Which lasts longer?
- The Novilla backs its mattress with a 10-year warranty; the Kow lists no warranty length. Both are 6-inch foam, so expect a shorter life than a thicker mattress.
- Which is better for a guest room?
- The Novilla, because the lower price and multiple sizes make it easy to fit a guest bed. Its medium-firm feel suits most sleepers.
- Do both work on an adjustable bed?
- The Kow is listed for adjustable bed use. The Novilla is not marketed for it, so check with the seller before bending it.
- Which is better for side sleepers?
- The Novilla states a medium-firm feel aimed at side, back, and stomach sleepers. The Kow does not state a firmness, so it is the riskier pick.
