We have been eyeing the one at Costco since last summer. We plan to buy it before our next trip this spring. We sleep on a memory foam mattress at home and I just can sleep on anything else anymore. Hopefully the topper woll be enough. My parents just got rid of their mattress in the Sabre completely and bought a memory foam one from Costco for 500 bucks. They loved it so much they bought one for home too.
We have tried a few. Our favorites came from Amazon and IKEA believe it or not.
Everyone's preference is different I suppose, but we also tried one from Kohls, Walmart, and TJ Maxx. We tried memory foam and filled versions. We liked the Ikea one because it was kind of like a hybrid between memory foam and filled.
We took one trip with the factory trip and I was in pain after first night. Went to Costco and bought a 17 inch pillow top deluxe mattress and a 2 inch memory foam topper. Figure if I'm to spend a lot time in bed have to be comfortable. Gave the factory mattress away to first person who would take it. Now its someone else's pain.
Have the exact same one as ependydad. Even the DW who didn't want memory foam for the house loves it. Just got another coupon from kohls and going to buy a couple for the kids beds now.
Don't! Go to Foam Factory (web site) and just order 3" pieces of their high quality foam. I got it just before our Christmas trip for the beds for my in-laws and they're really happy. It wasn't too expensive and I think cheaper than what toppers from Kohls would have been.
