A Purple Mattress is a great option for couples, because of its unique structure. The grid technology that makes up the mattress gives people the support and comfort they need. Air pockets are created under the sleeper so as to create a breathable setting.
Purple is temperature-neutral, so if your partner tends to run hot at night you can still both sleep peacefully. The mattress will provide protection against heat trapping, which is a huge selling point for couples. Thus the non-toxic materials used to make Purple mattresses are better than memory foam, because they do not hold heat.
It is also worth noting that a Purple Mattress does not leave a body indent, so if you are a restless sleeper you will be able to move around comfortable during the night without disturbing your partner. Ultimately, these features make Purple a great choice for couples.
