Mattress causes back pain
"Bought this bed to replace king bed we had for 21 years. Research said it was good choice for extra tall person. Delivery was fine, set up easy. Mattress caves in sitting or sleeping near the sides to the point it is useless as other reviews have stated. Havent had it 30 days yet but every night I get low back pajn for how much sag is jn the mattress and wake up with pain. I have yet to be able to sleep through the night with it. For the price of the mattress and the foundation( which has no way to attach a headboard to it), it is very disappointing."
