Good quality for the price.

Nice and comfy. I weigh 155 lb and it's just right for me. Easy setup bed in box for me but would be easier with some helper.

Hello scharlie! we're very sorry to hear about this accidental purchase and the difficulty you're having with moving the mattress. We completely understand your frustration. We've checked and found that this is a Walmart-fulfilled order, and we can see that the platform has already processed a refund for you. Since you are unable to move the heavy mattress, and Walmart handles the fulfillment and returns for this order, we kindly suggest contacting Walmart Customer Service directly. They may be able to arrange a pickup or provide guidance on how to handle the item without having to transport it yourself. We sincerely apologize for the inconvenience and appreciate your patience. Thank you. Warm regards, GREOO Support Team
