Yes. Manchot Endurance is a 14-inch hybrid mattress built for heavier sleepers and for couples who put more combined weight on the bed. It uses higher-density foam and a heavier outer-zone wire gauge than Essential and Signature.

We don't publish one. In our experience, Endurance suits sleepers from about 180 to 300 lb best, per person. That range comes from fitting people to mattresses, not from a load test, so we don't list a maximum. If you're under it, Essential or Signature will probably feel better, since Endurance is firmer. If you're over it, contact us before ordering and we'll talk it through. More on reading weight figures: Do mattresses have a weight limit?

No. The warranty terms don't set a body-weight limit. Warranty covers sagging greater than ¾" and material defects under normal use. Full warranty terms available at checkout. More detail: Does body weight affect a mattress warranty?

A platform bed with a solid surface, an adjustable base, a slatted frame with slats no more than 3 inches apart, a box spring in good structural condition, or a flat, solid floor. Wider slat gaps or a sagging or unstable frame can affect warranty coverage. At 14 inches, it also needs fitted sheets with a deep enough pocket.

The perimeter uses three rows of 2.3 mm coils. There is no separate perimeter edge wire.

It uses a higher-density foam specification and a heavier outer-zone wire gauge than Essential and Signature, while keeping the center-zone gauge at 2.3 mm.

No. Two sleepers put more combined load on the mattress than one sleeper does. If that is what you're thinking about, Endurance is built for it. If not, Essential or Signature will likely suit you. Endurance also feels firmer, around 7 to 7.5 out of 10, and a lighter partner will notice that more.

Choose Endurance if your bed carries more weight than usual, from a heavier body, two sleepers, or both. If it doesn't, Essential or Signature will likely suit you as well, for less. Endurance also feels one step firmer. If you'd rather have a softer surface, start with Essential or Signature.

Sleep on it for at least 30 nights, then decide any time within 100 nights. If it isn't right, one email starts the return: we arrange pickup from your home and refund what you paid. Original packaging isn't required.

Long-term durability is not predicted by coil count, thickness, price, or warranty alone; a more useful question is how the complete build handles repeated load, including whether the load-bearing middle is deliberately reinforced and verified as part of the whole system. Endurance's coil unit went through a 100,000-cycle fatigue test alongside the coil units of Essential™ and Signature™, at a third-party ISO/IEC 17025-accredited laboratory under QB/T 1952.2-2023. It's a test of the coil unit, not of the finished mattress. It isn't a weight-capacity test, and it doesn't predict how many years a mattress will last. We don't publish a lifespan in years.

For Manchot, lumbar support means reinforced structural support through the center third of the mattress. In Endurance, the center third uses 2.3 mm tempered-steel pocket coils, the same center gauge as Essential™ and Signature™, and the outer zones use a heavier 2.1 mm wire gauge, so the center wire is about 10% thicker.

We use “lumbar support” to describe the design and structure of the mattress, not a medical outcome.
