What Is a Sex Blanket?
A sex blanket is a multi-layer sheet with a waterproof barrier layer laminated between an absorbent top layer and a non-slip or soft backing. It protects the mattress and bedding beneath while being washable after each use. Sex blanket vs. regular towel compares the two most common approaches.
How Sex Blankets Work
The construction is typically three layers: a soft, absorbent top (microfiber, bamboo, or flannel), a waterproof membrane (TPU or polyurethane), and a backing layer. The top absorbs fluids; the membrane blocks penetration to the mattress; the backing keeps the blanket in place. Full sex blanket review covers our hands-on testing of top options.

Frequently Asked Questions
Are sex blankets actually waterproof?
Quality sex blankets with a TPU membrane are genuinely waterproof at their rated absorbency. At very high fluid volumes they can saturate and allow seepage; oversizing or doubling up prevents this for heavy-use sessions.
Can you put a sex blanket in the washing machine?
Yes. Most sex blankets are machine washable on a gentle or normal cycle in cold or warm water. Avoid hot water, fabric softener, and bleach, which degrade the waterproof membrane over time.
What size sex blanket do I need?
For most couples, a 60x80 inch blanket covers the active area without needing to reposition it during a session. Larger sizes (80x90 or full queen/king) cover the entire bed surface for those who prefer total protection.
