I think the big 'pregnancy' pillows are a bit of a gimmick really. Agree if you want a long bulky pillow you could roll up a single duvet. I used 2 normal pillows: one under my bump and one between my knees and they worked just as well (and I had SPD so was in pain most nights - the pillows really helped)
Yes I have it, has really helped as I don't need to turn over as much (and therefore wake up to turn). I don't move the pillow, just pull the long bit between my knees from behind when facing the other way. Got mine at 30w. HTH
OK, this is my 4th pregnancy and at last I've found a pillow that is supercomfy -and as I have SPD that's a challenge. It's on the pricey side but worth EVERY penny. Also, I know it'll be great for breastfeeding and in the future for just sittung up comfortably in bed. It just moulds to your body. It's v. long and at night it is easy to turn over and just take the top part with you. I got it from Mamtoto and it was £39.95 - I would usu. baulk at spending that on a pillow but do. It's great and i regret not buying one in a prev. pg.
