Currently my hasband and I are sleeping on an air mattress because I just cannot decide which (kind of) bed is the best to buy. We tossed out our previous conventional mattress; because it was like sleeping on a bed of nails! The mattress springs felt as though they were pushing back at me - it was awful. I am curious what kind of bed, if any, you all would suggest. A sleep number bed? The tempurpedic memory foam mattresses?? Either/or ... they are both pricey - but when you need a bed that won't hurt your back, you pay the price. I would really appreciated anyones/ everyones opinion and suggestions, please!! Thank you, Thank you! Slenderthread
