You are looking at what, the "Sleep Innovations" mattress, I believe.
First, I have one, second my son liked ours so well he bought one for his off-campus apartment.
Third, my daughter also likes ours so well, she wants to buy one for her apartment, but is waiting to "save up the $$$."
My wife thinks it is a bit firm for her, but definitely O.K.
I, the one who decided to buy it, am the only one who HAS NOT slept on it, so I can't give a personal opinion.
Know that they gave away a fair number of these, based on getting people to post reviews....so that may skew reviews a bit.
However, last September, wife said we need new mattress for guest room. I am the wheeler/dealer in the family and I set out on the quest.
I had no intention of buying a foam mattress and told several mattress sales people so. But, in doing research, actually decided to give one a try -- it's the guest room after all.
Glad I did. Price is cheap. Deliveried to door for free and everyone who has slept on it likes it -- well -- wife so/so -- but she is sort of like that Mikey character in the cereal commericals. So, a "so/so" from her is pretty good.
I picked it based on reviews and also based on Sleep innovations pillows wife, I and my son have had for more than a year and love.
SO: Have not had it through a summer. We got ours in September, when temperatures are in the 60s here. Son got his in January. I have read some people who say they can be hot to sleep on.
Ours does not get regular use, and we have had it less than a year, so no clue on durability (for your use, though, it should be fine).
I got the thickest one they offer -- in hindsight, I would probably get the next thickness down (too tough to wrestle with linens). Son got the Eight-inch, I think and loves it.
You can also buy the same mattress through
Walmart....it was a wash when I compared the prices.
To sum it up, I would go for it for your use.
