Because we use premium materials and components, we do not have a strict weight limit for our mattresses. They are designed to support a lot of weight. However, as guidance we suggest that 350 lbs. per person or less is recommended for the best experience, or 700 lbs. in total. Obviously, heavier sleepers require better structural support, and are best served when their mattress is reinforced by a solid foundation or platform and sturdy frame.
Box springs are not recommended for heavy sleepers. If slats are used on a bed frame, the spacing should be greatly reduced and thicker slats used. With heavier sleepers, rotating the mattress from head-to-toe frequently will also encourage more uniform wear.
