My mattress sucks. It gives no support whatsoever and I wake up with back pain on a weekly basis. FI sleeps on it and has no problem whatsoever. He was out of town this weekend to visit family, so I took my Mom to see The Expendables 2 (entertaining by the way!) and we stopped at JCPenney's. I caved and ordered a fantastic Serta mattress with a plush top for FI and plenty of support for me. I got the box spring for free, including shipping and delivery, and they'll take away my crappy mattress as well. It comes on Saturday so now I know the sore muscles and back pain will soon be gone!
