Electric Air Bed Double Size & Sheets

This is a double-sized air mattress with a built-in electric pump.
A dedicated fitted sheet is also included.

Size: 201 x 152 x 40 (cm)
Weight: 7.4 kg
Load Capacity: 320 kg

Purchased around August of last year. It was opened once to test inflation but has not been used.
The fitted sheet has not even been removed from its bag.
The original box has been discarded, so it will be sent in its dedicated storage bag.

I believe the main unit and sheet cost around 13,000 yen.
I am selling it because it is no longer needed.

The instruction manual has been lost and is not included.
If necessary, I can try to contact the seller to inquire about it.
