great mattress 2 thumbs up

we were a little concerned about buying a mattress without trying it first but we saw all the good reviews about this one and decided we would give it a try knowing that we would have 30 day money back guarantee. The mattress is heavy, 131lbs and when we started cutting the bag it inflated so quickly like in 70 seconds thankfully we got it on the bed ok. Our first night's sleep was wonderful. Keeps Us cool, we live in Florida so that's a nice Factor. The softness of the bed is good but also has support for back. When I get into bed my husband on his side doesn't feel it so that's a plus too. We bought King and the 14 inch thickness, which makes it higher but we were surprised that our sheets still fit. love the mattress and highly recommend

Better than our Sleep Number

Love this mattress. We have purchased 3 of these, one for our fifth wheel RV, one for our smaller camper, and one for our guest room in our apartment. The mattress is in our RV (we lived in full time for 4 years) has held up perfectly. The firmness is “just right”. We recommended this to our son that was needed a new mattress. He purchased it and now our other sons have decided to go with this mattress when it's time to replace their current mattress.

No pain waking up

This mattress is surprisingly good. At first when I laid on it I felt like maybe it might be too firm. After sleeping on it all week, it is actually perfect. If a bed isn't good I will wake up with lower back pain and since I am a side sleeper I will have pain in my upper leg area. I can honestly say no pain. The price is good and I love not spending thousands on a mattress.
