I bought the bed and mattress on the 20 January, i have had some great nights sleep. I can not see how the buttons can stick in your side. I always have a mattress protector on mine and then a fitted sheet. Right from the first night, I knew I had chose right. Over a month later it has as got better. I would suggest a mattress protector for any and all mattresses, it is a shame the others did not try this, the instruction advise you to use one to enable an exchange. Look forward to going to bed.
