Good quality and price!

the mattress is very good! It comes in a vertical box, so all you have to do is just cut the plastic and it will roll out. Naturally it takes a bit of time to fully expand, but not a long wait. very good for the price.

Great mattress- great humor!

Mattress is great. Everything turned out great. I have to give props to whoever wrote the directions on this thing! Not that I needed it- but it got a few chuckles from the family! Well done!

Excellent quality at a reasonable price

I was a little skeptical to order a boxed mattress and after doing some research, I decided on this Mainstays 8" Tight Top Innerspring Mattress. Wal Mart consistently delivers quality products under their Mainstays brand and that seemed to be a safer choice than going with an unknown off brand. The mattress arrived in a rectangular box and weighed just over 40 pounds. I opened the box and unwrapped a portion of the plastic that reveals a safe tool to open the remainder of the packaging. As the plastic is removed, the mattress begins to decompress and it is actually quite entertaining to watch. Within seconds, I had a full size mattress ready to install. I placed it in the bed frame and let it settle for a few days even though it felt great from the start. The mattress is solid! The quality is exceptional and the pillow top offers added comfort. I used this on a loft bed for my niece and she slept comfortably. I have since ordered a second mattress for my nephew and he loves it. The price is incredible for such a high quality mattress and delivery was so convenient. I highly recommend!
