Linenspa Explorer 6" Innerspring Mattress review

The Linenspa Explorer is a 6-inch innerspring sold on Walmart.com and aimed at children: the listing says the profile is ideal for bunk beds, trundle beds and toddler beds and calls its innerspring support perfect for growing bodies. A plush layer of comfort foam sits on top of the springs, and the foam carries cool gel infusions. The twin was $89.98, down from $108.00, when we checked. The listing is a little inconsistent: the title calls the mattress firm while the feature list says medium-firm, so expect a firm-leaning feel. The features also do not name foam or fabric certifications, which Zinus and Mainstays list for their similar coil models. Like the other Walmart picks it arrives compressed in a box and falls under Walmart's free 90-day returns. It costs $21 more than the Zinus Core Comfort and adds a comfort foam layer over the coils.
