I hear you. I just bought a new mattress myself (old serta viscoe latex mem foam mattress has gotten too soft in my sleep spot, so it's time...) Bad sleep habits are tough to break for sure, but prone sleeping may be a big part of your issues.
Yeah, am male, and not subject to the same female age changes with the wild temperature swings, etc. you ladies have to deal with, but can certainly empathize that it makes everything with sleep harder... I have always slept pretty hot, but have lost a good amount of weight recently, and actually get cold a lot easier now ... But it's kinda extremes now for me... When I am hot, I'm hot and when cold , I'm cold... Seasons are part of it and I keep my house at 64 here in northern winter climate, so I've switched my bedding up for Winter (thick long staple cotton 600 thread count sheets plus down duvet and cover) and lighter weight 300 TC cotton sheets for summer (often just flat sheet and no blanket)... and light blanket with flat sheet in spring and fall. Seasonal bedding setups, in other words. For me, It's gotten to be bedding formula tweaks by season, 😂.
Any brands you recommend for/against? I had a Serta perfectsleeper plush pillow top for seven years and now it’s starting to sag, Sam’s Club is allowing me to change it, I was thinking of about getting the beauty rest regal sleep, plush pillow. I am a side sleeper and need a softer mattress
Serta Perfect Sleeper - Extra Firm. Had a 3” memory foam topper on the first 8 months or so until it was broken in and now it’s perfect.
Serta perfect sleeper signature FIRM. First time I’ve slept all night (10-6) for 20 years! I think I am going to write corporate Serta & thank them!
Can I just say. I think your best bet is probably Costco or Sam's. They have an excellent return policy so if you hate it, return it. That being said quite a few mattress companies will allow you to buy it and if you hate it return it. Sometimes they don't even want it back and will ask you to donate to a local shelter. I personally went with a hybrid by serta and medium. I actually love it . And you can always throw a topper on yours and make minor changes to the comfort level. This can all be done if you piece out your bed. Their are motorized bed frames that can really benefit you . You could get a split mattress so you can get a 0g bed and on the cheap.
In short. Your old one is a better quality mattress than your new one. More coils for support, better for quality for there foam. Serta Perfect Sleeper is a better quality mattress at 10 years old vs a brand new Sleepys basic.
For comparison you didn’t just get a Perfect Sleeper, you got a higher end perfect Sleeper that retails for $1300 vs a $500 no brand. Perfect sleeper you had, has over 1700 coils/innersprings. The Sleepy’s Hybrid has 440 coils/inner slings so it has a 1/4 of the support as your previous. So that’s what you’re feeling in terms of quantity. Also I’ll send the foam specs for both too, and it all comes down to quality https://preview.redd.it/e5bf4mhvelpf1.jpeg?width=1179&format=pjpg&auto=webp&s=3774b2a28c255cde9a0d2eac94a77b06040abbc3
But Serta is still higher quality than the Sleepys Basic Hybrid. Especially depending on which level of Serta, perfect sleep collection vs iSeries. Serta makes good products, not top of the line by any means, but I wouldn’t consider them low end. Just about every major brand has a ‘low’ end section to be competitive in price, but that’s just part of the overall picture.
If it’s not in your budget to buy a more expensive mattress with better cooling technology, consider a topper with cooling benefits. Coil for coil you probably had more in the Serta, which is why it may feel more supportive, as the Sleepys basic hybrid is a more basic coil structure/count.
