The Perfect Mattress

I have purchased between 6-8 or more of these over the past 13 yrs for me, my youngest son, our spare room, my niece, my daughter and her hubby, and now my oldest son and his wife, plus replacements a couple of years ago for a few. It's a GREAT mattress. It always fully inflates nicely out of the box and feels great in the way of firmness and support. I can't say enough good things about this mattress. It keeps its shape over the years, doesn't sink in or even start to for several years and that is a very, very tiny bit so that it's not noticeable. I used to be well over 300 lbs and there wasn't a dip on my side. I'm 180 now and just feel sheer comfort and support with this mattress. It's like sleeping on a semi-firm cloud. Get them for your household. You won't regret it.

If I'm being honest it was an impulse purchase, I really needed a new mattress but I didn't have to look for very long because I found one very quickly and affordable on the Walmart app. It had a deal so I got $20 off, the mattress had great reviews and was even recommended to me by someone I know who also purchased this mattress at a Walmart store. So far since I've received the mattress I've loved every second of it. Definitely a much needed and affordable upgrade.

This is a repurchase!!! We bought one years ago and after a baby and breastfeeding to having a toddler spill things we decide to get a new bed and repurchased. We loveeeeeeee this bed!!! I recommend!! We had bought another prior to this and it was a nightmare!! Save yourself time and stress and go with this one. It’s such a good buy and you don’t have to worry.
