  • Size:

    When it comes to mattresses, one size definitely doesn’t fit all. The mattress should be longer than the tallest person sleeping on it. The bed width should allow enough space to fold your arms behind your head without going beyond the mattress edge or touching your partner’s elbows (for two adults, we recommend either a queen or a king).
