• Wake up feeling refreshed and invigorated when you purchase this twin size 10" foam and pocket spring mattress and memory foam topper value bundle. This medium-firm twin mattress is filled with premium, high-density foam and is constructed with ultra-supportive material. The foam is CertiPUR-US Certified so it''s free from heavy metals, phthalates, BPDE, formaldehyde and has reduced VOCs so you can rest easy knowing your indoor air quality won''t be compromised. Featuring individually wrapped pocket spring coils, this comfortable mattress will fill gaps of your sleeping form, limit motion transfer and allow airflow through the mattress. This innerspring mattress is fantastic on its own but when you add the 2" thick cooling gel-infused memory foam topper that keeps you sweat free, inhibits allergens and provides whole body support, you have just hit the bedding lottery. Versatility is always a plus and this twin-size mattress is compatible with trundle beds, platform beds and adjustable bed frames. When using with a standard bed frame a box spring or other foundation is required. Safety is paramount and this premium mattress has a 16CFR 1632 fire rating while the cooling mattress topper is certified with both 16 CFR 1303 and 16 CFR 1632 fire ratings. Both pieces arrive compressed for easy movement. Simply remove the packaging, lay flat and allow to expand.
