Bedding Accessories Guide (2026): The Add-Ons That Actually Upgrade Your Bed

A great bed is more than a bedsheet. The right accessories protect your mattress and pillows, improve sleep and save you money by making everything last longer. Here is what each one does and whether it is worth buying.

The essentials

Protect the big-ticket items first

Your mattress is the costliest thing on the bed, so a waterproof mattress protector is the single highest-value accessory — it takes the spills, sweat and stains so the mattress does not. Our complete mattress protector guide covers types and sizing.

Then upgrade comfort

Once the mattress is protected, the next upgrade you feel every night is a good pillow. Match it to how you sleep, and add a pillow protector underneath to keep it fresh.
