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.

Very Comfortable and therapeutic
The lift recliner has saved me from pain with the message feature and the heat feature so many restless nights after my back surgery now fewer sleepless nights the product I would recommend to anyone but to those who are healing from surgery. Money well spent.
