Do mattresses lose support faster with heavier people

I'm about 280 lbs and have gone through two mattresses in three years. The first was a cheap memory foam that developed a huge crater. The second was a hybrid that started sagging around month 18. Is this just my life now, or are there mattresses that actually hold up for heavier folks? I'm tired of waking up in a ditch.

Dude, same. I'm 250 and my last foam mattress lasted barely two years before it felt likw a hammock. I think weight definitely accelerates wear. But I also think some brands use cheaper foam that breaks down no matter what.

Its not just weight, it's also how you use it. If you're heavy and sit on the edge of the bed every day, that's going to kill the edge support faster. But yeah, higher density foams are key. What did you have?

At 280 you're probably outside the warranty for most mattresses anyway. They usually have a weight limit around 250 per person. So good luck getting a claim honored.

I'm 230 and my latex mattress has held up great for 5 years. No sagging. Maybe look into latex? It's denser and more resilient.

Latex is expensive though. And heavy. But if it lasts, maybe worth it.

All mattresses lose support over time. Heavier people just speed up the process. It's physics. You can't fight physics. But you can buy a firmer mattress and rotate it regularly. That helps a bit.

Rotating is key. I rotate mine every 3 months. Also, a mattress topper can extend the life if you catch the sagging early. But once it's cratered, it's done.

Have you considered sleeping on the floor? Zero sag. Just saying.

Floor is too hard for side sleepers. My hip would be screaming.

Wait, I'm the OP but I can still reply? Anyway, I didn't mention but I'm a side sleeper. So I need something that doesn't bottom out. I tried a firm mattress once and it was like sleeping on a board. But soft ones sag. Catch-22.

Look for a hybrid with coils and a high-density foam comfort layer. The coils give support, the foam gives cushion. But make sure the foam is at least 4 lb density. That's the sweet spot.

Also check the warranty terms.Some brands void warranty if you don't use a proper foundation. And they might prorate. So read the fine print.

SkepticalSally

Honestly, at 280, you might want to look at beds designed for heavier people. There are brands like Big Fig or Titan that specifically cater to higher weights. They cost more but might last longer.

Or just lose weight? Kidding. Kind of.
