I'm about 290 lbs and have killed two mattresses in three years. Both were around $600 queen hybrids from big-box stores. The sagging starts around month eight and by year two there's a visible dip. I'm willing to spend more but I don't know where the point of diminishing returns is. Is $1500 enough to get something that lasts five years? Or do I need to go higher? I'm not looking for luxury, just something that won't turn into a hammock.

How much should I spend on a mattress that won't sag
Honestly, at your weight, $1500 is probably the minimum for a decent hybrid with a strong coil unit. The cheap ones use thinner gauge coils and low-density foam. Look for something with a coil count over 1000 and foam density at least 1.8 lb/ft³ in the comfort layers. That's usually where the price jumps.
I'm 260 and went through the same thing. I spent $1800 on a latex hybrid three years ago and it's still flat. No sagging at all. It was painful to swipe the card but I've already saved money compared to replacing a $700 mattress every two years.
Tessellate, what brand was that? And did you buy online or in a store? I'm nervous about buying without lying on it first.
Buying online is fine if they have a good trial period. Just check the return policy carefully. Some charge a fee or require you to donate the mattress. Also, give it a full 30 days before deciding. New mattresses feel different after they break in.
You could also consider a firm innerspring with a latex topper. Cheaper than a full latex mattress and you can can replace the topper when it wears out instead of the whole bed.
It was Sleep on Latex. I got the medium firmness. Their customer service was helpful when I called to ask about weight limits. I think they rate their mattresses for up to 350 lbs per side.
The industry standard Warranty usually covers sagging over 1.5 inches. But at 290 lbs you might sink deeper than that even on a good mattress. Make sure you understand what the warranty actually covers before you buy.
Also check the foundation. A lot of sagging complaints come from using a box spring that's not supportive enough or a slatted frame with gaps that are too wide. That can void the warranty too.
That's a good point about the foundation. I'm usign a cheap metal frame with slats from my old bed. Maybe that's part of the problem. The slats are about 4 inches apart.
4 inches is pretty wide. Most manufacturers recommend no more than 3 inches, and some want 2. You might be getting uneven support. A solid platform or a bunkie board coould help.
Sleep on Latex actually has a foundation guide on their site. I'd check that before blaming the mattress entirely.
If you're handy, you can add a sheet of plywood over the slats to firm up the base. Cheap fix. Just make sure it's ventilated or you might get mold tbh.
Thanks, everyone. I'll start by fixing the foundation and then look at the $1500-$1800 range. That feels more reasonable now.
