Mainstays 6 in Twin Innerspring Mattress vs Linenspa 6 Inch Gel Memory Foam Mattress

Buy the Mainstays if you need a firm, low-profile twin for a bunk, trundle or guest bed and want springy support. Buy the Linenspa if you want memory foam that contours and relieves pressure, and you can accept a softer, slower-reacting feel. The Mainstays has a large owner base and a 4.2 rating, with complaints centered on thin padding over the coils. The Linenspa is the better pick for side sleepers and adults; the Mainstays suits kids and lightweight sleepers.

• Choose the Mainstays if you need a firm 6-inch twin that fits a bunk or trundle and you prefer the bounce of springs over foam.
• Choose the Linenspa if you want gel memory foam that cradles pressure points and you sleep on your side or move around less.
