An air mattress is like a waterbed, relying on displacement rather than providing real support.
The Simmons Beautyrest mattresses use a pre-compressed, individually pocketed coil unit, which provides upward and contouring support, which maintains the natural alignment of your spine.
It’s this, that makes those hotel Beautyrest mattresses so comfortable.
Unfortunately, their coils are made of raw steel, not tempered steel.
Under your weight, they won’t hold up well nor last very long.
I have a mattress that is made with the same kind of coil system as the Simmons Beautyrest, having a higher coil count, and those coils made of double tempered steel.
Also, the upholstery is Natural Talalay Latex, which is far more resilient than the polyurethane foam used in a hotel grade Beautyrest...which is more resilient than the memory foam used in retail grade Beautyrests.
The Natura of Canada Greenspring is the mattress I’m recommending.
I have had a number of customers sporting your same weight, and this is what works, world well, and lasts a long time.
Specially, it’s their Firm model and a Pure Bliss 3” Plush Natural Talalay Latex Topper to go on it.
The topper will need replacing every few to several years, but not the mattress.
The only downside to this, is the wait time.
The factory is currently closed, due to the Covid-19 pandemic.
They are scheduled to reopen on May 4th.
It’ll take 3-4 weeks after that to receive the mattress.
The mattress comes with white glove delivery and there’s no sales tax.
The latex topper arrives via ups.
