i have chronic illness and am partially bedbound right now. but i like to have functional time and sit/recline while getting things done on a lapdesk and that sort of thing. i've made my own bolsters, i've piled up pillows and tried all kinds of things but this wedge saved the day. first of all it covers the gap between bed and wall where all pillows go missing. even my custom bolsters eventually ended up down in the chasm. this wedge is perfect - it's firm but very comfortable. plus it keeps me from being straight up against the wall (i don't have a headboard) which can be painful on my neck, i need some room to maneuver and get comfortable. if i need to adjust things i'll just add on another pillow to make the right shape but instead of having 9 pillows on my bed trying to make myself comfortable, it's the bolster plus one. i don't bother taking it off at night, i just use it as a headboard (and then my arm doesn't fall into the chasm either, yay!). it does take up some inches on the top of the mattress but the way i sleep it works out fine. or you can just remove it @ bedtime. i was hesitant because it's not an inexpensive purchase but now that i have it i am SO glad and it's totally worth the investment. seems quite reasonable actually as it's a very large bolster/wedge. i would buy it again and recommend it to ANYone who spends any time hanging out in bed - it really saves your back and neck!
