Jamdok Cot Mattress Topper for Camp Cots & RV Bunks 75x30x3 in Polyester Fiber — Roll-Up, Machine Washable

A compact, roll-up 75" x 30" x 3" mattress topper by Jamdok designed to add cushioned support to camp cots, RV bunks, and narrow twin beds.

This Jamdok cot mattress topper converts thin, narrow sleeping platforms into a noticeably softer, more comfortable surface while staying easy to store and transport. Sized at 75" x 30" with a 3" loft and filled with resilient polyester fiber, it layers over cots, foam mattresses, and bunks to reduce pressure points and improve sleep comfort on the road or at home. The topper is machine washable, comes with corner ties to secure it to a frame, and rolls into a compact cylinder for travel.

Will this fit my camp cot or RV bunk?

The Jamdok topper measures 75 inches long and 30 inches wide, matching most standard cots, narrow twin platforms, and many RV bunks. Its 3-inch thickness provides a noticeable cushioning effect without raising you too high in compact sleeping spaces.

• Exact dimensions: 75" x 30" x 3"
• Best for camp cots, narrow twin beds, RV and camper bunks
• May be used over thin foam mattresses for added softness

How portable and packable is the topper?

The topper is built for travel: it rolls tightly and secures with an attached storage strap so you can stash it in a trunk or camper. When rolled, it occupies only a fraction of its expanded volume, making it practical for road trips, camping, and limited storage spaces.

• Includes sewn-in tape to roll into a compact cylinder
• Light enough to carry and store in small compartments
• Quick to roll and fasten for on-the-go use

How comfortable and supportive is the 3" polyester fill?

The polyester fiber fill strikes a balance between soft cushioning and lightweight support, improving sleep comfort over thin surfaces. It creates a plush top layer that complements firm cots or adds extra softness atop a memory foam mattress without significantly changing firmness.

• Provides moderate cushioning—adds softness without excessive sink
• Recommended to use on a cot or mattress; floor use may reveal the base
• Pairs well with memory foam for enhanced comfort

How do I care for the topper and keep it in shape?

The topper is machine washable for convenient cleaning after outdoor use or travel. For best results, allow the pad to fully expand in a ventilated area for 48–72 hours before first use and follow washing care to preserve loft and shape.

• Machine washable—follow gentle cycle and drying recommendations
• Air out 48–72 hours after unpacking for full expansion
• Corner tie ropes help prevent slipping while sleeping

Who this is for: The Jamdok Cot Mattress Topper is ideal for campers, RV travelers, and anyone using narrow twin or cot-style beds who wants a simple, lightweight way to improve sleep comfort without bulk. It's a practical choice for weekend adventurers, road-trippers, seasonal guests, or anyone needing a stowable pad that adds cushioning to portable or space-limited sleeping setups.
