very high quality.. best of both worls traditional coil and foam\ cooling gel for you night sweaters
As with anything you must do the research and know what youre buying before you buy it.my wife and I spent several months researching mattresses. we went from store to store and and felt like we were buying a car. after reading many reviews and what would be best for us we decided to buy the Serta Icomfort hybrid observer super pillow top queen. we are both NOT large people so I'm not sure how this mattress would be for 2 very large people as stated in one of the other reviews. We went to Raymour Flanagan in Quakertown Pa (our first time there) and found they have an HUGE amazing selection of Serta mattreses.from memory foam to Hybrids etc. not to mention many other brands. we decided to go with the basic reverie adjustable base.we are completely happy with out mattress and adj base.the serta icomfort hybrid is really amazing to sleep on its firm and a lot of support but feels like super soft cool jellow.it really is amazing. the main reason we went with the hybrid is you get both of the best worlds. you get traditional coil with memory foam ontop. my wife is going though night sweats due to menopause and the little crystals in the memory foam really do keep her cooler at night. I suffer from siadic lower back pain that shoots down my leg from driving a lot.the reverie adj base has whats called 0 gravity position and is truly amazing with this matress.the feet come up as well as the back (alittle) to where you have 0 pressure on the lower back which is amazing. I suggest you go lay on these beds try them out and spend a couple hours laying on youre side how you will sleep. I hope this review helps I really wanted to share my opinion and Iam in no way affiliated with serta or the furniture store.
