Compare 10-, 12-, and 14-inch mattress thicknesses
All three Steady mattresses share the same queen footprint and medium-firm feel. Choose your thickness based on the height of your bed frame, how high you want to sit at the edge, and the pocket depth of your fitted sheets.
Queen Memory Foam Mattress FAQs
What size are the queen mattresses?
Each mattress measures 60 inches wide by 80 inches long. The 10-, 12-, and 14-inch measurements refer to thickness. Check the pocket depth on your fitted sheet, especially if you use a mattress protector or topper.
Does a thicker mattress feel firmer?
Monvane describes all three Steady models as medium-firm. Thickness tells you how high the mattress will sit on your frame. For a practical fit check, add the mattress thickness to your bed base height.
Does the memory foam help reduce motion transfer?
The Steady mattress uses a six-layer construction designed to absorb movement and reduce how much you feel when someone shifts on the other side of the bed.
What kind of bed frame works with a Monvane mattress?
Use a queen base with firm, even support. A compatible platform, slatted frame, or foundation can work. Check the base maker’s guidance for foam mattresses, including any limits on slat spacing.
How long does the mattress take to expand?
Unpack and unroll the mattress on your bed base. It needs no assembly. Allow up to 72 hours for full expansion and follow the instructions included with your mattress.
Where does Monvane ship mattresses?
Monvane offers free standard shipping to the contiguous 48 states and Washington, D.C. See the shipping policy for current processing and delivery estimates.
Can I return a mattress after opening it?
Before cutting the factory seal, ask Monvane Support about eligibility and return shipping costs for your mattress. See the refund and return policy for how to start a return.
What if my mattress arrives damaged or expands unevenly?
Contact Monvane Support promptly if you see shipping damage or if the mattress remains uneven after 72 hours. Include your order number and photos of the mattress and packaging.
