This is a single item. I purchased this about 2-3 years ago and used it a few times. It's in relatively good condition, but as it's an outdoor item, there may be minor scratches and dirt. Please purchase only if you understand this. THERM-A-REST This is a 3-season closed-cell mattress that folds up like an accordion for storage. The Z Lite Sol has an aluminized surface. Compared to models without aluminization, the insulation is improved by 20%. (The Z Lite does not have aluminization.) The folding design allows for quick unfolding and storage, so you can easily take it out and use it without stress, even for short breaks. Size: R Specs Size: 51 x 183 cm Storage size: 51 x 13 x 14 cm
