By one for yourself, buy one for your mom... I think you'll like it.
This pad is great. It's so much nicer than my old Thermarest- no more pressure pains in the middle of the night! It's so plush and comfortable that it's responsible for convincing my non-camping mother to go camping.
The foot pump works well, although adds bulk in terms of packed size. I also, cannot for the life of me, fit this back into the sack it came in. I paid close attention when unrolling it, but just can't get it to fit. Kind of a bummer, but getting/making a stuff sack to accommodate it isn't too big of a deal.
4 stars because of the stuff sack issue and not having used it for long yet- I can't attest to durability just yet.
