When I purchased mine I used the recommended weight chart which said I needed 20 pounds and I got one in 20lb 60x80 and 20 lb 48x78 in length to switch out. I also wanted the blanket to be really heavy. I thought the heavier the blanket, the better it would feel. I like to use mine on the couch too. Like a dope the first blanket I got was 20 lb 60"x80" and that size was too big for the couch and hung down to the floor. The smaller twin sized one was a much better size for the couch.

Turns out I am a side sleeper and noticed that mid way through my sleep, my back, tips of my toes/feet and side was hurting really badly and became sore. Then I would flip to the other side and had the same pain issues as the night progressed. I would wake up limping from the pain and soreness. I am not a back sleeper at all and found I would wake up from my sleep on my back. I must have been in so much pain during my sleep that I moved to sleep on my back to relive the pressure from too much weight from the 20 lb blanket.

I decided just for shits and giggles to get a smaller 15 pound 48x72 weighted blanket. The lighter one made a huge difference!! This time I chose one with smaller diamond shaped pockets (4"x4") instead of the usual rectangular/square 6"x6" sized pockets. The smaller sized diamond shaped pockets ended up holding the glass beads closer to each other which distributed the weight more evenly over me. Turns out even though I am 220+ pounds, the shorter, 15 pound blanket feels so much better and is easier on my hips, back and feet and the pain has no gone away. I sleep way more soundly now that the pain is gone.

Since you are taller why not give a 15 pound or a a 20 pound 48"x78" length blanket a try? The 25 pound blanket might just be too heavy for your body and causing this pain. Sometimes the weight is too much and puts too much pressure on our joints, muscles, back and hips and ends up hurting us in the long run.

My favorite one, the 15 pound, 48"x72" length might be a tad bit too short for you, but may work for you if you don't like covering yourself up to your neck like I do. I'm short (5' 5") so the length is perfect for me.

There are few Amazon sellers that sell the longer 48"x78" length ones, and I found a few on Amazon for under $50 that come in 15 pounds and 20 pounds. As a matter of fact my favorite one (15 pounds 48"x72") was only $25.99 on sale with the smaller diamond pockets filled with glass beads, and I see some other sellers having sales for them around $30-$45 on Amazon from time to time.

The bigger 20 LB 60x80 queen sized one I got hurts me the most and the smaller/shorter 15 pound blanket feels way better for me. Your blanket is probably way too heavy for you.
