Frequently Asked Questions
Is the Recharge | Extra-Firm good for back and stomach sleepers?
Yes. Its firm foams and lumbar zoning make it ideal for sleepers who prefer extra support without sinking into the mattress.
What is a tri-zone coil system and how does it help?
A tri-zone system is an advanced innerspring design that divides the mattress into three support sections. In the Recharge mattress, the center third—where your hips and lower back rest—uses a firmer, heavy-gauge steel coil for targeted lumbar support. The top and bottom thirds use a slightly more forgiving coil. This design provides powerful, reinforced support right where you need it most, promoting better posture and helping to alleviate back pain.
Who is an extra-firm mattress best for?
An extra-firm mattress is ideal for stomach sleepers, as it prevents their hips from sinking and keeps the spine properly aligned. It's also often preferred by back sleepers and some heavier individuals who require maximum support. If you love the feeling of sleeping "on top" of your mattress rather than sinking into it and want a solid, durable feel, the Recharge Extra-Firm is an excellent choice.
Do you offer delivery and old mattress haul-away services?
Yes, at Mattress King, we provide convenient delivery services across Oklahoma. We pride ourselves on offering fast, one-day delivery options.
