The Explorer is an 8" high innerspring mattress by the Parklane RV Mattresses division of Parklane Mattresses (formerly Paramount Bedding) near Portland, Oregon. The other mattress in this set is The Traveler, a 7" high model.
Like The Traveler, The Explorer is supported by Bonnell coils. This mattress has a 390 coil count in Queen size, which Parklane indicates is higher than most other coil spring RV mattresses. The innerspring is flexible enough that Parklane RV Mattresses rolls it up (using a patented process) and boxes it for shipping.
Unlike The Traveler, The Explorer is a single-sided mattress. This allows it to be plusher, with a thicker Eurotop and thicker quilting (together ¼ of the mattress height), meaning more SuperSoft foam under the sleeper for more cushioning. Parklane says, "You won't believe this is an RV mattress. It feels like an expensive home mattress and will give a great night's sleep."
The Explorer is sold online by Parklane RV Mattresses, They also list it on Amazon, where it is the Parklane RIQ#### Quilted Mattress. The four numerals (####) are the width and length of the model in inches:
RIQ3474 - RV Twin
RIQ3874 - Residential Twin
RIQ4974 - RV Full
RIQ5374 - Residential Full
RIQ5379 - Full XL
RIQ6074 - RV (Short) Queen
