Do not buy this protection plan!
Warning! The details of this Warranty are misleading and make you feel like they will pretty much replace anything. I am trying to have stained discolored cushions replaced on lounge chairs, less than six months old. Talking to a customer service representative is out of the question. They ask a few multiple-choice questions and base your claim on that. My claim was denied and that is the end of it. I have spent $80.99 on two different asurion protection plans need and now I feel like I have wasted $162.00. I'm not happy and will never buy this protection plan again. Now I have to find and purchase new cushions for replacement.

Great chair
You sit on it more than in it. It's a bit firmer than my old one, but hopefully it will soften up as the years pass. Otherwise, great chair, easy to put together. The theater lights are a very cool touch at night.

Paid for Protection, Got Rejection — Asurion Makes Claims Unnecessarily Difficult
I purchased the 2-year Asurion protection plan along with my Mcombo recliner, expecting peace of mind in case something went wrong. Unfortunately, when I actually needed to use the plan, the experience was frustrating and disappointing from start to finish.
I submitted a claim and uploaded every document available to me—order confirmation, invoice details, and proof of the protection plan purchased through Amazon. Despite this, I received a generic rejection email stating that “documents are missing,” without any explanation of what exactly was lacking.
Trying to resolve the issue was even more frustrating. Finding a working customer service number was unnecessarily difficult. When I finally managed to speak with a representative, the interaction was unhelpful and dismissive. The agent requested a document that does not exist in my purchase records and offered no guidance on how to obtain it. There was no attempt to clarify, assist, or move the process forward—only a rigid insistence on requirements that were not properly explained.
At no point did I feel that Asurion was trying to help resolve the claim. Instead, the process felt designed to discourage follow-through.
A protection plan should simplify problems, not create new ones. Based on this experience, the coverage feels like wasted money rather than a safety net.
I would strongly recommend reconsidering before purchasing an Asurion protection plan.
