Havnby SnugNest Extension Pad for Pickup Cabin Mattress — Adds 6'3" Diagonal, Foam Top & Inflatable Base

The Havnby SnugNest Extension Pad is a dedicated mattress extender that stretches your pickup cabin sleeping surface to accommodate taller users when paired with the Havnby Pickup Mattress.

If your truck bed or cabin mattress feels too short, the SnugNest Extension Pad gives you extra sleeping length by using the front passenger footwell. This companion pad combines a soft foam topper with an inflatable base to create a continuous, supportive surface that integrates with the Havnby Pickup Mattress. It’s intended strictly as an add-on and requires the Havnby Pickup Mattress to function as designed.

How does the extender increase sleeping length for tall people?

By filling the space created when the passenger seat is moved forward, the SnugNest adds diagonal length across the cabin. The result is a sleeping surface that reaches approximately 6'3" measured along the diagonal, helping sleepers over 6'2" find adequate legroom without altering the vehicle.

• Uses front passenger footwell to extend mattress reach
• Provides an added 6'3" diagonal sleeping length for taller users
• No vehicle modifications required—seat simply moves forward

What comfort and support features does the pad provide?

The top layer is a soft foam topper that bridges toward your center console, creating a smoother, more comfortable transition from mattress to pad. Underneath, an inflatable base supplies firm support and stability so the surface feels even across the entire sleeping area.

• Soft foam top for pressure relief and a seamless feel
• Inflatable base adds firm, stable support during sleep
• Designed to align flush with Havnby Pickup Mattress to avoid ridges or gaps

How easy is it to install, pack away, and maintain?

Setup is straightforward: move the passenger seat forward, inflate the base with your Truck SnugNest pump (pump not included), and position the foam topper. When you’re done, deflate, fold, and stow the pad compactly—ideal for frequent travelers who need convenient storage.

• Quick inflation/deflation for fast installation and removal
• Folds compactly for efficient storage in limited truck space
• Routine spot cleaning recommended to keep foam and cover fresh

Can I use the SnugNest Extension Pad by itself?

No — this product is engineered to work only as a companion to the Havnby Pickup Mattress. The dimensions and connection points depend on the Havnby mattress; buying the extender alone will not create a proper sleeping surface.

• Sold as an accessory, not a standalone mattress
• Requires Havnby Pickup Mattress for correct alignment and support
• Designed specifically to match Havnby footprint and contours

Who is this for: The Havnby SnugNest Extension Pad is built for tall campers, overlanders, and truck travelers who already own the Havnby Pickup Mattress and need extra legroom without modifying their vehicle. It’s especially useful for people taller than 6'2" seeking a smoother, longer sleep surface that packs away easily between trips.
