## Questions & Answers

**Q: How does the cushion come boxed? (The box packaging) It's for a gift. Does someone have an image they can share, please?**
A: It comes in a brown cardboard box.  The pillow is squished into a plastic bag.  You must wrestle the pillow from the bag and allow to sit and fluff up.  My advice- buy something else.  This was gifted to me on Monday.  Under 140 pounds, sat on it for 5 minutes.  The pillow was flat and I could feel my tailbone touching the seat through the hole in the cushion.  They do not provide an invoice, packing slip, info on how to return or who this was a gift from.  I emailed twice- no reply.  Rcvd a c/b a few minutes ago but they can’t find any info for my pillow.  I sure how to return.  This item is way too expensive for what it is and it doesn’t do what it says.  I am so appreciative to be thought of and that someone is willing to spend this much on a special pillow to help me but this pillow is a fail.  I was sent the seat cushion and lumbar pillow.  The lumbar pillow hasn’t really been tested much (I’m not over the moon about it).

**Q: How is the seat cushion for bigger people, 6'6" around 380 lbs? Will it hold?**
A: I am in a similar category - 6'5'  ~ 350 lbs -- I did not like it -- it is too small -- it hits my legs in the wrong place -- and ( for my liking ) is NOT wide enough ....it requires constant adjustment to remain comfortable

**Q: The photo says 16x16x3, the description says 15.5 x 18 x 4 inches. Which one is correct?**
A: I found the dimensions for standard and large sizes per the manufacturer:

Standard: 18 W x 15.5 L x 4 H inches 
Large: 21 W x 18 L x 5 H inches

**Q: Has anyone tried it on a couch? i’m in my 70s and finding i have lower back pain after i’ve been sitting on the couch. hard chairs are fine**
A: I have 5 lumbar (& 5 cervical) vertebrae which are messed up in multiple ways.  I’ve found a good lumbar support cushion helps more than a seat cushion support. That said, it doesn’t matter how many different types of lumbar supports (with or without a seat support—I have tried many), that I try or use, if the chair or couch I am sitting in has lost its firmness/support, or was just too soft and not well-supporting to begin with, I will still have pain—even with the addition of constant heating pad use.  I had a very nice Lay-Z-Boy recliner (though I never use the “recline” feature—it is more comfortable for me to have a rocking recliner and use an ottoman so I can keep my knees bent, and provide more relief of my lower back at the correct angle for me).  When my back pain got considerably worse, my recliner was about 6 years old.  I paid several hundred dollars for a Laz-y-Boy repair man to reinforce/replace the springs in it and replace the foam cushions.  That, plus a lumbar support pillow and heating pad, kept the recliner usable for me for about another 4 years.  Then, I decided to just buy a new one.  I bought another Lay-Z-Boy, but still use a lumbar support pillow (one that goes as high up on my back as I could find: 17 inches), & of course, a heating pad about 80% of the time.  I found trying to use a seat support on my new chair caused me to sit too high in it, and all the support it provided was hitting me wrong.

I guess my point is: these types of supports can definitely help (depending on how severe your spinal problems are), or enable you to extend the life of a chair you like, but at some point, you may need to upgrade whatever you’re sitting in, and shop with back support as your top priority.  Also, just like with mattresses: stay away from “all memory foam” construction.  It breaks down over time and becomes a spongy mess.   Look for good old fashioned firm spring support, though it is usually more expensive.  You can always buy a memory  foam topper for it—and when it becomes flat, just replace that!
