There is no “Best” bed size, only what’s best for you. Take into account how big your bedroom is, how much walking distance you need around the bed, furniture in the room, and how much space you need when you sleep (ie, do you sleep curled up like a baby, or like to stretch out!). Also keep in mind if you are single or share a bed with a partner and/or pet. While you need enough space, the most important consideration for your rest is sleeping on a comfortable and supportive mattress. Use our mattress dimensions guide to see which Nectar is right for you.
