Why medium firm for a guest room?

Medium firm suits most sleepers. It supports back and stomach sleepers. Side sleepers get enough cushioning. This versatility is key for guests. You do not know their preferred position.

What to look for in a guest mattress

Durability matters because guests come and go. Look for high-density foam or strong coils. A removable cover is a plus for cleaning. Consider a mattress that ships compressed. It is easier to move into a home office.

How to choose the right size

Measure your guest room first. A full or queen fits most spaces. A twin is fine for a single guest. Make sure the mattress fits the existing frame. Check the room's door width for delivery.

Maintenance and longevity

Rotate the mattress every few months. Use a waterproof protector to guard against spills. Vacuum the surface regularly. Follow the care instructions from the brand. This extends the mattress life.
