Q: What is the shipping investment for oversized items?

At Madevast, we believe in transparent pricing. We offer a flat-rate shipping fee of $6.99 USD for all domestic orders across the United States, including our heaviest mattresses and ergonomic chairs.

Q: What is the expected delivery window?

Our typical delivery cycle is 3 to 10 business days. This includes a 1–3 day precision quality check and 2–7 days of secure transit via our specialized freight network.

Q: Do you deliver to P.O. Boxes?

Because our products are high-volume, precision-engineered furniture, we require a physical residential or commercial address. We cannot fulfill orders to P.O. Box locations.

Q: How do your mattresses arrive in a streamlined box?

We use industrial-grade vacuum-compression. This allows our premium mattresses to be delivered in a manageable footprint without compromising the structural integrity of the high-density foams.

Q: Will I need to assemble my ergonomic seating?

Minimal assembly is required to protect the chair’s moving parts during transit. Each unit includes a professional-grade tool kit and a step-by-step guide for a seamless setup.

Q: Is there an adjustment period for new support systems?

Yes. Your body requires a “break-in” period of approximately 21–30 nights to adapt to a high-performance support system. We recommend consistent use for at least 3 weeks.

Q: What is the 60-Day Comfort Guarantee?

If you aren’t completely satisfied, you may return your product within 60 days. We provide a full refund and, unlike other retailers, we cover 100% of the return shipping costs.

Q: How do I return a mattress that has been unboxed?

Simply contact support@madevast.com. Since the mattress cannot be re-compressed, we will arrange for a free removal service or coordinate a donation to a local charity in your area.
