Hi plop,
Welcome to the mattress underground.
To specifically address where you can buy a traditional innerspring mattress, there are a couple of choices within a half hour from Manhattan.
Shovlin Mattress
Orange Mattress in New Jersey
While these folks make superior quality mattresses, not all will cost the kings ransom.
The Clean Bedroom in NYC
The Clean Bedroom has a nice innerspring, but it is over your budget even with TMU discounts
It’s advisable to steer clear of chain stores when shopping for mattresses in your price range, as many of the options they offer tend to be subpar in quality.
Mattresses from reputable manufacturers like Trusted Members of TMU are more likely to endure for five years or even longer. From personal experience, my mother-in-law purchased a BeautyRest mattress from Raymour and within a year, it developed a sizable indentation under her hip—quite a disappointing outcome for an $1800 investment. Considering this, it’s concerning to think what they might offer for $700.
Independent retailers such as Beloit Mattress and Gardner Mattress (that offer traditional innerspring mattresses, albeit, no in your local vicinity) prioritize product quality regardless of price point because they directly interact with customers and face scrutiny if their products fall short of expectations. In contrast, larger chain stores and marketing-focused mattress companies handle such issues differently—they typically levy a restocking fee to offset costs and swiftly move on as it becomes a volume play for them.
Companies like @EngineeredSleep offer a classic mattress which is a hybrid but acts like a traditional mattress.
@DLX Has their essential mattress which is a bit firmer, which is perfect for stomach and back sleepers and when on promotion falls right in your budget. Also a hybrid, the two sided acts more like a traditional mattress.
Both of these “classic” mattresses offer generous trial periods, and if you reach out to them, they’ll gladly discuss the assurance of purchasing based on specifications and expected comfort.
Living here in NJ there are several options in the southern part of the state, but the ones mentioned above are within a half hour from NYC so it is an easy trip. Probably easier than getting around the city.
We can address guidance on the mattress specifics and matching one to your specific profile, but the folks at all of the independents mentioned are seasoned professionals to place you on the right track.
Best of luck,
Maverick
