Grand Firm - Sale Price Luxury Mattress

Spring Air is considered by many to be an "S Brand" due to their popularity and level of quality but their prices say differently; theirs are very affordable luxury beds! 

I personally own a mattress that is very similar to the Grand Firm, that is also made by Spring Air. I can't express enough exactly how happy I am with my bed! 

This particular model is available in both custom/odd and standard sizes. It contains a low profile coil spring unit that's foam encased, high resiliency foam, high density foam, a back alignment pad and an organic cotton cover. There's not much that this model is missing and it's definitely a great solution for anyone looking for a firm that isn't a total brick - one that accompanies the natural curvature of your body.
