It looks good in terms of quality... the size is as advertised... we'll have to see if it will do the job of lifting the mattress on the head side to prevent sagging!!
Well... the pillow is good in terms of quality, however... the fake valve inside broke on the first pressure and stayed in my hand... then I brought a hand compressor and it inflated somehow... of course, it doesn't need much inflation, otherwise the mattress will rise too high... but the Chinese have done something with the plastic valves because even with the compressor, it was difficult to inflate... so if you want something to work right away, I don't see it happening
