Available details list portable tri-fold single mattresses in 3-inch and 4-inch thicknesses.
Listings show two common fills: memory-foam-filled tri-fold mattresses (listed as 100% foam) and hard-side waterbed mattresses constructed with 100% vinyl.
Most listings describe the mattresses as 'Medium Firm,' while some hard-side waterbeds are labeled 'Medium Plush,' indicating a range from medium-firm to medium-plush.
Waveless waterbeds are described as providing approximately 80%–90% motion reduction with three to four layers of wave-reducing fiber. Semi-waveless models are described as providing about 60% motion reduction with one to two layers.
Portable tri-fold single mattresses are described for multi-functional indoor and outdoor use, including camping, guest beds, toddler use, travel, yoga, and parent–child activities.
