Don't Waste Your Money
Bought this 2 year protection plan and come to find out it doesn't even cover simple stuff like our mattress losing it's shape and stability. A mattress should last longer than 1 1/2 years before it starts caving in and the foam and springs start to give. So disappointed. Asurion Protection is a waste of money.

love my new chairs
best darn chairs for big people (450lbs)..iv ever purchased.the fabric is way thicker then the cheaper chairs thats out there.....only thing i have a slight concern about is the connectors ((made of plastic)) which hold the frameing in place....that could lead to a problem....thats what usually fails on most chairs iv purchased in the past...so i bought a 2 year protection plan just for that reason.but if i was to give it a rateing i would give it a 9 out of 10...one more thing if your a tall person its alot easerier to get up out of the chair because it sits higher then cheaper versions.
