I have to admit that for the price $139 I was a little leary of the quality of the Sultan Havberg spring mattress. But Oh my Lord, This bed is fantastic!!! I have slept through the nights with no tossing and turning. I ABSOLUTELY LOVE IT!!! This was a HUGE bargain and big bang for my buck!! I would highly recommend this mattress to anyone who likes firm and comfortable. You will not find a better bargain.
I am a college student who can barely afford food, bought this mattress for 90 dollars at ikea, at first i thought it was good but after a week I started having sever aches on my back elbows and neck. I cant afford another mattress so whenever there is no one at home I sleep on my roommate's bed "he will kill me if he finds out" or in the living room.
