Questions & Answers

  • Q:

    "can you flip this mattress? and how many coils? and gauge number?"

    • A:

      Thank you for your question and I apologize for the delayed response. This mattress looks so comfortable! The queen size mattress has 532 coils, and 13.25 coil gauge. This is a one-sided mattress and does not need to be flipped.

  • Q:

    "I have a couple of questions. Based on the first question of the difference between euro and pillow top, I'm assuming a euro top is firmer than a pillow top? Next question, what is a split mattress as this one is described? Is it a split mattress, or split foundation? Thank you."

    • A:

      If we were to put the firmnesses on a scale, it would be as follows: Firm -> Plush -> EuroTop -> PillowTop. When a mattress says that it is a split mattress that means the foundation is split.

  • Q:

    "what is difference between eurotop and pillow top"

    • A:

      Euro top doesn''t include a pillow top on the mattress.
