Review on 🛌 SleepRight Splintek Side Sleeping Pillow Memory Foam - The Ultimate Side Sleeper's Pillow by Dionne Reyes

I bought my first of these pillows in 2010 and it has lasted 4 years (better than any other pillow I have used). I bought my second pillow in 2014 and love it too. I've never noticed a strong odor from them - both times I've used them right out of the box. It looks like my second pillow needs to be replaced BUT I just read on the manufacturer's website that the softness or firmness of your mattress may affect the size (thickness) of the pillow you need. I found out I changed my mattress last year and I bet that's why the pillow doesn't feel thick enough. I used to use 4 inch pillows (I'm 5ft 6 inches) but next time I'll buy a 5 inch pillow as my new mattress is much softer than my old one. I see a pillow of the same size/thickness sold for $70 at Revain, $109 at another online store, and $139 on Splintek's website. How can it be the same pillow? I contacted the manufacturer to find out. Update my rating when I get a reply from you.
