What's the best mattress for a 300 lb back sleeper

I'm 6'2" and about 305 lbs. I've been sleeping on a cheap innerspring that's sagging badly in the middle. As a back sleeper, I wake up with lower back pain every morning. I need something that won't break down quickly and provides solid support. Budget is around $1500 for a queen. Any real-world suggestions?

At your weight, you'll want a hybrid with thick coils and high-density foam. Avoid all-foam beds unless they're specifically rated for higher weights. Look at the Titan from Brooklyn Bedding—it's built for bigger folks and has a good coil system for back support.

I'm 280 and back sleeper. I got the Saatva Classic in firm. It's been two years and no sagging. The coil-on-coil design feels supportive without being rock hard. Customer service was decent too.

How long did your last mattress last? If it was only a few years, you might need to rotate it regularly. Also, a firm larex hybrid could be a good bet—latex is dense and doesn't sag like memory foam.

Latex might be too bouncy for some, but it's durable. Check out Sleep on Latex—their firm model is very supportive and has a 9-inch profile. I'm 250 and it's been Solid for me.

Don't overlook the foundation. A weak box spring or slats can make any mattress sag. Make sure your bed frame can handle 300+ lbs.

I tried the Titan and it was too firm for me, but I'm a side sleeper. For back sleeping, firm is usually better. They have a sleep trial, so worth a shot.

What's your current mattress? If it's a pillow top, those tend to sag faster. A tight-top design might last longeir.

Current is a Serta perfect sleeper, about 5 years old. Started sagging around year 3. I'll check out the Titan and Saatva. Foundation is a solid platform bed, so that should be fine.

Five years is about average for a cheap innerspring at your weight. The Titan should last longer with its denser foams. Also, consider the WinkBed Plus—it's designed for heavier sleepers and has a firmer feel.

One more thing: if you go with Saatva, ask about their high-density foam option. It costs extra but might be worth it for durability.

Also, check the warranty. Some brands void coverage if you don't use a specific foundation. Read the fine print.

I've heard good things about the Avocado mattress for heavier folks, but it's pricier. Maybe look for sales.

Have you considered a mattress topper? A firm latex topper could extend the life of your current bed temporarily, but with sagging, it's probably best to replace.
